NORTH MELBOURNE

Ryan Bastinac: Coming off a disappointing 2014 when he struggled to adjust to a more outside role. Blessed with elite endurance and has had one of his best pre-seasons in recent years. Is confident that he can produce for the Roos, whether he is required at stoppages to cover Levi Greenwood's departure or on a wing or half-forward flank.

Ben Cunnington: Now one of the Roos' prime movers, Cunnington took his game to a new level in 2014, winning his first club best and fairest award. Has improved his fitness this pre-season and enters 2015 well placed to become one of the game's elite inside midfielders.

Daniel Currie: A capable AFL ruckman but has struggled for senior opportunities. Was trialled last year in a forward/ruck role but is a natural ruckman, so if Todd Goldstein stays fit he is likely to spend much of 2015 in the VFL.

Nick Dal Santo: The former Saint barely put a foot wrong in his first season at Arden Street last year and at 31 has enjoyed another strong pre-season. Likely to spend most of his time in the midfield again in 2015, but his poise and precise ball use should be called upon at half-back at times.

Trent Dumont: The inside midfielder is one of the players who could help cover Levi Greenwood's departure to Collingwood. Enjoyed an excellent first season with North Ballarat last year and has worked hard to improve his fitness. Played in the Roos' opening NAB Challenge game against Adelaide and seems well placed to make his AFL debut this year.

Will Fordham: The first-year rookie has been eased into his first AFL pre-season, with the Roos keen to build his core body strength before exposing him to an AFL training load. The running midfielder is likely to spend 2015 developing in the VFL.

Sam Gibson: Has dominated North's time trials again this pre-season and is well placed to resume his role as the club's hardest-running on-baller this year. Although his kicking can let him down at times, Gibson runs harder than any other Roo in both directions.

Todd Goldstein: North's No.1 ruckman is over the calf niggles that troubled him earlier this pre-season, making his return against Hawthorn last Sunday. Shapes as one of the Roos' most important players this season when he will be called on again to shoulder the club's rucking duties largely on his own. 

Brad McKenzie: Played North's opening two NAB Challenge games but struggled to have an impact. An elite kick but needs to impose himself on matches more. Out of contract at the end of this season, the 21-year-old faces a make-or-break year.

Braydon Preuss: The rookie has made a strong impression in his first pre-season at Arden Street. The 206cm ruckman moves well for his size and has reasonable endurance. Grew up playing rugby league in Townsville and has work to do on his game sense. Likely to spend 2015 developing in the VFL.

Andrew Swallow: The Roos skipper started his pre-season early, joining the small party that ventured to Utah for a high-altitude training camp in November. Back to full fitness after the Achilles tendon injury that sidelined him for the first seven games last year and should return to his best in 2015.

Ed Vickers-Willis: The first-year utility has only recently started full training after needing time to build strength through his core and hips. Given his delayed start to the pre-season, Vickers-Willis is likely to need an extended stint in the VFL before he can push for an AFL debut. Has played his best football in defence in the past two years, but can also play as a tall midfielder.

Daniel Wells: After his injury-disrupted 2014 season, Wells was one of the senior Roos who made an early start to their pre-seasons on November's Utah training camp. North fans did not get to see the outside skills of Wells and Nick Dal Santo in partnership as often as they would have liked last season, but the duo should form a damaging partnership this season. Well placed to return to his best after a solid summer on the track.

Jack Ziebell: Ziebell had post-season shoulder surgery that has limited his contact training, but he has completed a full summer of running that included November's Utah camp. Played both of North's opening two NAB Challenge games and was impressive against the Hawks last Sunday. The big-bodied on-baller will be one of the Roos' main men at stoppages again this season, but will spend time in attack after pinch-hitting successfully there late in 2014. - Nick Bowen

ADELAIDE

Rory Atkins: Talented left-footer who performed consistently well in the SANFL last year and nearly broke through for an AFL debut. Was having a stellar pre-season until he injured his knee, which will mean a delayed start to the season.

Brad Crouch: A quickly emerging superstar, Crouch rebounded amazingly last year from an Achilles injury and then a broken leg. He is tough on the inside, polished on the outer and hasn't put a foot wrong all pre-season.

Matt Crouch: Although more as an inside midfielder at West Lakes, the younger of the Crouch brothers has no trouble getting his hands on the ball. Ankle surgery in January was a setback but he is back into full training.

Patrick Dangerfield: One of the game's brightest stars, Dangerfield's power is almost unmatched in the AFL. He's a game-winner who has recovered from a knee injury but will endure constant speculation about his future until he decides whether to stay or leave at season's end.

Richard Douglas: The 2010 winner of the Malcolm Blight Medal as the club's best and fairest, Douglas finished last year relatively strongly and has not missed a beat this pre-season. A crucial player when firing.

Cam Ellis-Yolmen: It has taken Ellis-Yolmen a number of seasons to develop but he is beginning to find the consistency required at the top level. He's a quick but big-bodied midfielder and was one of the club's best on Thursday night against Geelong with 23 disposals.

Mitch Grigg: A classy left-footer who usually makes good decisions when in passion, Grigg is entering his fourth year at West Lakes and needs to take the next step and play regular senior football.

Sam Jacobs: He benefited greatly last year from losing weight and was able to accumulate more possessions around the ground. A minor knee injury was a slight setback earlier this year but his fitness has improved and he will be ready to go for round one.

Sam Kerridge: Probably the fittest player at West Lakes and it allows him to play a variety of roles. He is good up forward, can run with players and holds his own in the midfield. A flawless pre-season has him placed to demand more senior games in 2015.

Riley Knight: A quality wingman/half-forward whose debut season in the SANFL last year almost pushed him into the senior side. Unfortunately an ankle injury has set him back and he will face a late start to the season.

Luke Lowden: After finally making his debut for Hawthorn last year the ruckman was traded to Adelaide where he needs to pressure Sam Jacobs for a place in the side. He can play up front in attack, which helps his cause.

Jarryd Lyons: Turned down offers to join a Victorian side last year to stay and his pre-season form has suggested he will throw everything at season 2015. In both NAB Challenge games he has been in the top five for Crows' possessions.

David Mackay: Has a firm grasp on the title of Adelaide's premier wingman. Is fast and has great skills on the outside. He's recovered from a minor hamstring strain, which recently robbed him of a few weeks' training.

Reilly O'Brien: The draftee ruckman impressed everyone in Adelaide's first NAB Challenge game against North Melbourne with 14 hit-outs, as well as some strong marks around the ground. Likely to spend the year in the SANFL.

Rory Sloane: A champion player who thrives on contests and lifts when the going gets tough. He is one of the club's most important players and has enjoyed a great pre-season, but is yet to re-sign with the club.

Scott Thompson: The veteran has had an interrupted pre-season because of hip surgery and more recently a hamstring injury. But his experience will help him recover quickly and as he showed last year, has got plenty left to offer.

Nathan van Berlo: Missed last year with a ruptured Achilles but has returned in the NAB Challenge this year and has his sights set on round one. He has trained fully since day one of pre-season. His on-field leadership and experience will prove hugely important in Adelaide's midfield.

Anthony Wilson: Rated the fastest player outside the AFL before the Crows drafted him, Wilson can play up on a wing or deeper in attack. He will have to develop his game before commanding regular game time in the AFL, but has taken well to a full-time football environment.

Matthew Wright: A natural footballer who has played several different roles over the years, from small forward to midfielder to tagger. Great pre-season will hold him in good stead to try to cement his place in the side. - Harry Thring

BRISBANE LIONS

James Aish: Stellar first season for the South Australian who played 21 games and averaged 18 disposals. Came with a reputation for being a quality outside ball user, but worked hard on his inside game to the point where he often started in the centre square. Polished midfielder who is out of contract at the end of 2015.

Dayne Beams: Huge off-season signing for the Lions, landing the Collingwood premiership player and Copeland Trophy winner. Beams has the perfect mix of inside ball-winning and the ability to go forward and kick goals. Will be his new team's primary midfielder and likely to get tagged most weeks, something he rarely dealt with at the Magpies.

Rohan Bewick: Started his career as a half-forward, but mixed his time between the wing and the occasional run-with role in the back half of 2014. Again will look to utilise his exceptional running power on a wing this season and build on the final 12 games of last year when he averaged 20 touches.

Billy Evans: The 187cm Evans was taken as a rookie after playing for Victoria Country last year. Is capable of kicking goals, but prides himself on winning the inside ball and will develop his game in the NEAFL this season.

Cian Hanley: Younger brother of Pearce, the 19-year-old will sit out the season after rupturing his ACL while captaining County Mayo in an All Ireland semi-final last August. When fit Hanley, an international rookie, is elusive and has good endurance. He has been undertaking his rehabilitation in Brisbane since November.

Pearce Hanley: The brilliant Irishman finished 2014 in stunning form, averaging 30 disposals over the final nine rounds. He will be sidelined until midway through this year, though, after requiring pre-season surgery on a hip. Hanley is agile, creative, quick, skillful, and arguably the Lions' most damaging player.

Matthew Leuenberger: The towering ruckman has had a strong pre-season after a meniscus injury restricted him to five games last year. At his best Leuenberger is one of the premier rucks in the AFL, with his first-class tap-work and athleticism around the ground. If he can remain healthy and forge a strong partnership with Stefan Martin, it will go a long way towards a successful season for the Lions.

Stefan Martin: One of the good news stories of 2014, Martin rejuvenated his career after he looked on the scrapheap midway through the year. He overcame three hamstring injuries in six months to play the final 12 rounds, average 22 disposals and become arguably the form ruckman of the competition. Competes well in the air, but once the ball hits the ground Martin is almost like another onballer.

Sam Mayes: Struggled a bit in his second season as Justin Leppitsch threw him all over the ground to continue his education. Mayes is a clever footballer with an exquisite kick and plays his best as an outside midfielder who can run to half-forward and kick goals.

Zac O'Brien: The hard-running O'Brien was rewarded for his strong NEAFL form with five senior games last year. Small in stature but big on work-rate, the 24-year-old had his moments too, kicking a late go-ahead goal in a win over Carlton and racking up 30 disposals against Geelong. Likely to spend most of his year in the reserves, but can do a more-than-handy job if called up.

Jack Redden: After 112 successive games to start his career Redden was sidelined for the final eight games in 2014 after ankle surgery. Has not missed a beat in the pre-season though and again looms as a central cog to the midfield with his relentless attack around the ball. Redden is always in the top-five tacklers in the AFL and averages 21 disposals a game over his career.

Nick Robertson: The young West Australian got some chances in his debut season and showed there is plenty to work with. Got caught out by the speed of the game on occasions and will go back to the NEAFL to work on that in 2015. Robertson is fearless and an aerobic beast, but needs to tidy up his skills to become a regular in the top team.

Tom Rockliff: The new Lions captain, Rockliff had a memorable 2014, earning his first All-Australian selection and winning his second best and fairest award. Entering the prime of his career, the 25-year-old is a ball magnet who works relentlessly across four quarters. Finds holes in opposition defensive setups and is an ideal player to link defence and attack. Rockliff is the heart and soul of the Lions.

Archie Smith: A project ruckman entering his second season, Smith continues to improve at a rapid rate. He has added considerable bulk to his athletic 201cm frame and looks comfortable mixing it with senior bodies. The former basketballer is likely to spend the season in the NEAFL, which will do him no harm at all.

Trent West: Was doing a fine one-out job early last year in the absence of injured Leuenberger and Martin before being struck down by his own ruptured ACL. West is due back by round six and he will be an understudy to the leading duo.

Dayne Zorko: Hard to believe Zorko is entering only his fourth season such is the impact he has had. The 26-year-old is in the Lions leadership group and moved from primarily a half-forward role into the midfield. He is a terrier around the stoppages and has explosive pace to burst clear. Capable of going forward and kicking goals. - Michael Whiting

CARLTON

Tom Bell: Took some major strides in 2014, playing 13 matches including the Blues' final eight games. At 187cm and 98kg, Bell is one of the big-bodied midfielders who have come into vogue in recent seasons. Was one of the Blues' best players in their NAB Challenge loss to West Coast and could help shoulder more of Carlton's inside midfield load in 2015.

Blaine Boekhorst: The Blues' first pick in last year's national draft has impressed in his first pre-season at Ikon Park. The 21-year-old is a classy outside on-baller but has work to do on his fitness and strength. Played in the Blues' opening NAB Challenge game against the Eagles and should play senior football in 2015.

Andrew Carrazzo: Has endured a tough run with injury in recent seasons, but looks set to put that behind him after completing his first pre-season in five years. At 31 he remains a vital player for the Blues with his ability to shut down opposition stars and is set to return for his first game of 2015 against Collingwood in Bendigo on Sunday.

Patrick Cripps: One of the Blues' brightest young prospects, Cripps has enjoyed a strong pre-season save for a minor ankle injury he suffered at the club's January training camp at Mt Buller. The Blues' first pick in the 2013 national draft was hit hard by injury last year, but is well placed to play plenty of senior football this year. At 190cm he is a powerful midfielder who excels at stoppages.

Ed Curnow: One of Carlton's best performers in the NAB Challenge loss to West Coast, the run-with midfielder is an elite runner and hard at the ball. Although his skills can sometimes let him down, the 25-year-old is a consistent performer who is likely to be a regular part of the Blues' midfield rotations in 2015.

Matthew Dick: The former Sydney Swan reads the play well, has good endurance and has particularly impressed Carlton's coaching staff this pre-season with his hunger to improve. The 20-year-old is well built and can play in the midfield or across half-back.

Andrejs Everitt: Fully recovered from the knee injury that prematurely ended his impressive debut season at Ikon Park, Everitt is likely to be assigned the run-with roles he excelled in last season. Highly rated by the Blues for his leadership qualities.

Bryce Gibbs: After his career-best 2014 season Gibbs will share the Blues' vice-captaincy with Michael Jamison this year. Unlucky not to make last year's All-Australian team, the South Australian appears ready to join the game's elite players in 2015. A hard-nosed ball-winner at stoppages and lethal with his foot skills in open space, he is the complete midfielder.

Billy Gowers: The first-year rookie is athletic and skilled on both sides of his body. The son of former Hawk and Brisbane Lion Andrew Gowers, at this early stage of his career he is an outside player best suited to a wing or half-back. His first season is likely to be a development year in the VFL.

Nick Graham: The third-year midfielder has enjoyed an uninterrupted preparation for 2015 after being troubled by leg problems in previous pre-seasons. Has improved his running this summer, particularly his efforts at intensity, and is one of the candidates to fill the hole left by Brock McLean's departure.

Nick Holman: Made his debut in the Blues' big loss to Port Adelaide in round 22 last year and will be eyeing more senior opportunities in 2015. The 19-year-old is a role player with a strong competitive streak and can play as a run-with midfielder or at half-back. Had minor knee surgery this pre-season but has returned to the training track.

Chris Judd: Was close to hanging his boots up at the end of last season, but decided to play on after rediscovering his love of football. The two-time Brownlow medallist remains one of the competition's best contested ball-winners, but is likely to spend time in attack this season. Finished last season strongly and will enter 2015 in far better physical shape. Named to play his first game this year in the Blues' clash with Collingwood on Sunday.

Marc Murphy: Had enjoyed an excellent pre-season until he suffered a minor calf strain in the Blues' intra-club game late last month. The Blues hope their skipper will be available for their final NAB Challenge game against Geelong next weekend, but insist he is no doubt for their round one blockbuster against Richmond. One of the game's most courageous inside ball-winners.

Fraser Russell: The category-B rookie has returned to football after a four-year absence when he pursued an elite athletics career as a 200m and 400m runner. The 22-year-old was a strong junior player and his speed will be a weapon, but he has to adjust to the lateral movement required in football. Will spend this season developing in the VFL.

Kade Simpson: The 30-year-old remains one of the Blues' most consistent performers and is likely to divide his time between the midfield and defence this season, depending on where he is needed most. Suffered a minor ankle injury in late January but played in the NAB Challenge loss to West Coast.

Dale Thomas: The former Magpie is primed for a big season after completing his first full pre-season in recent years. Finally free of the ankle pain that had dogged him since 2012, the Blues are confident Thomas can return to the 2010-11 form that made him one of the best players in the competition.

Brad Walsh: The rookie is hardened for a first-year player after playing senior WAFL football with Peel Thunder last year. He has adjusted well to AFL training and has impressed the Blues with his professionalism. An inside midfielder who captained Western Australia at last year's NAB AFL Under-18 Championships.

Robert Warnock: Has completed his best pre-season in recent years and is well poised to reclaim the Blues' No.1 ruck mantle after being dropped late last season. Impressed in Carlton's intra-club game last month and the club is confident the 28-year-old has his best football in front of him. Named to play his first NAB Challenge game against Collingwood in Bendigo on Sunday.

Mark Whiley: The former Giant made a solid start to his first pre-season at Ikon Park before being sidelined with an Achilles tendon injury. The 22-year-old is still two weeks away from returning, but the 188cm on-baller should enjoy senior opportunities this year.

Cameron Wood: The former Brisbane Lion and Magpie finished last season in fine style, coming off the rookie list to lead Carlton's ruck division over the final six rounds of the year. Wood will start this season on the rookie list again, but played as the Blues' sole ruckman in the NAB Challenge loss to West Coast. - Nick Bowen

COLLINGWOOD

Taylor Adams: Collingwood sees Adams as the man most likely to step up and assume more midfield responsibility following the departures of Luke Ball and Dayne Beams. The 21-year-old is expected to go to the next level this season.

Mason Cox: Recruited from Oklahoma State University, the former college basketballer joins Fremantle's Aaron Sandilands as the tallest player in the League (211cm). Cox is likely to hone his craft in the VFL this season, but has already impressed the Pies with his improvement.

Jack Crisp: Recruited from the Brisbane Lions, as part of the Dayne Beams trade, Crisp is expected to add more depth to the Magpies' midfield. Renowned for his toughness inside the contest.

Jordan De Goey: Firming for a round one debut after an impressive first pre-season at the club. Relishes the contest and refuses to take a backward step against more experienced opponents.

Sam Dwyer: Knee and groin injuries played havoc with the midfielder's 2014 campaign, limiting him to 13 games. The 28-year-old hopes he can re-establish himself in Collingwood's best 22 and recapture the form he showed in 2013.

Nathan Freeman: Freeman was one of the strongest performers on the training track throughout the pre-season, keen to make up for some lost time. The speedy youngster had his 2014 season ruined by a serious hamstring injury.

Matthew Goodyear: The Calder Cannons product is renowned for his athleticism and decision-making under pressure. Has impressed the Magpies with his desire to do the hard work this pre-season.

Levi Greenwood: Signed with Collingwood after seeking more midfield time, despite finishing third in North Melbourne's best and fairest count last season. Has shaken off a foot problem and the Pies hope he can be a solid contributor through the engine room this season.

Brodie Grundy: A down year of sorts for the young big man in 2014, but Collingwood sees it as part of his development. The Magpies view Grundy as their ruckman of the future and he will be given every opportunity to turn himself into a genuine front-liner.

Brent Macaffer: Macaffer is well on track in his recovery from a second knee reconstruction and the Pies hope he may return at the midway point of this season. The midfielder turned himself into one of the best run-with players in the League in 2014.

Scott Pendlebury: The skipper is set to take on even more responsibility this season, following the departures of premiership players Dayne Beams, Luke Ball, Nick Maxwell and Heritier Lumumba. Remains one of the best players in the AFL.

Steele Sidebottom: Sidebottom is coming off a career-best year, in which he averaged 26.7 disposals a game. More midfield time meant a lift in the star utility's consistency and the Magpies hope he can go to another level to cover the loss of Beams this season.

Dane Swan: With a self-described "putrid" season behind him, the Magpies are confident Swan can return to his All-Australian levels from past years. The ball magnet was slowed by off-season hip surgery, but has fought back and is raring to go in 2015.

Josh Thomas: Likely to assume an expanded role through the midfield this season following Beams' departure. Has had to fight back from a skin infection in his hand as a result of fending off a would-be mugger while on holiday in Los Angeles in the off-season.

Jarrod Witts: Set to play his first game of the season in the VFL on Saturday after recovering from off-season shoulder surgery. Witts' ruck partnership with Grundy shapes as crucial to the Magpies' finals hopes.

Clinton Young: Young's raking left boot and ability to carry the lines are an important part of Collingwood's game style. Has had an interrupted preparation this pre-season and is still up to two weeks away with a hamstring complaint. - Ben Guthrie

Big things are expected of ex-Giant Taylor Adams in 2015. Picture: AFL Media



ESSENDON

Kurt Aylett: The former Giant was delisted by the Dons at the end of last season but then re-drafted as a rookie. He played two games for the Bombers last year and can be used in a range of spots, mainly through half-back or a midfield role where his hard running comes to the fore.

Tom Bellchambers: Bellchambers' horror 2014 season is behind him and he is ready to shoulder the ruck load this year after the departure of Patrick Ryder. A pre-season ankle reconstruction ruined the big man's campaign last year and although he returned for eight games, he never reached his peak. At his best he is a smart tap ruckman and dangerous tall forward option.

Alex Browne: The Bombers' medical team treated Browne's knee reconstruction conservatively, particularly in the latter stages. It meant he took a little longer than hoped to get back into full training, but now there, the midfielder is going well. His injury struck at a bad time – he appeared likely to fit into the first-choice Essendon line-up last year – but will be aiming to make up for lost time in 2015.

Adam Cooney: The former Western Bulldog has had a healthy pre-season, even showing some of his trademark dash at training sessions. Brought to the club to provide some experience, speed and goalkicking prowess through the midfield, Cooney should add spark to the Bombers' line-up.

Jonathan Giles: With three goals against St Kilda last weekend, Giles showed why the Bombers were keen to sign him during last year's trade period. The former GWS ruckman was squeezed out of the Giants' regular side last year but should get plenty of opportunities this year at Essendon with Ryder gone.

Brendon Goddard: Goddard is due to play his 250th game in round three and enters a 13th AFL season in excellent shape after trimming down slightly and noticing the difference. Likely to swing between the midfield and half-forward again, where he has been able to contribute 35 goals in his two seasons with the Bombers. His recruitment as a free agent at the end of 2012 couldn't have been better for the club.

Will Hams: Injured an ankle during a training session in February but the Bombers were relieved that it was not as bad as first thought. Hams' tenacity and hard-at-it attitude has many admirers at the club, and they will be hoping he can have more luck with his body after hip problems curtailed his 2014 season.

Dyson Heppell: There was a scare at Bomberland when Heppell went down with a knee injury two weeks ago, but it was only minor and the star midfielder should be soon back training after surgery. They cannot afford to be without him for long, given Heppell's importance to the Bombers' midfield. He signed a five-year contract recently tying him to the club until the end of 2020, and he looms as the club's next captain.

Heath Hocking: The club had hoped Hocking's groin surgery in December would only sideline him until the end of January, but it has not recovered to that timeline and he's in doubt for the start of the season. He played with the groin problem last season, when he spent another year as the club's go-to stopper.

Ben Howlett: Gives the Bombers some tackling presence and a hard edge around the stoppages. Showed some flair last year when he surprised by booting five goals against Richmond, but is generally a no-fuss player who gives his all.

Elliott Kavanagh: A big year looms for Kavanagh, who put himself on the trade table last year but ended up staying at the Bombers. He has had a good summer but needs to put consistent performances together to earn his senior spot and then hold it. He is composed when in possession and has good foot skills, and Essendon will be hoping the top-20 pick can find his niche.

Jake Melksham: After a really strong season in 2013, being used as a run-with midfielder, Melksham didn't manage to find the same level of consistency last year. With confidence, Melksham is a damaging and dangerous player for the club. He can use the ball, kick goals, and isn't afraid of going hard at the ball.

Zach Merrett: Essendon's first pick at the 2013 NAB AFL Draft, Merrett burst onto the scene last year as a creative and crafty half-forward. He'll still play there a bit this year, but after spending summer with the midfield group, Essendon can expect to get more out of the smart left-footer around the ground. Has great work ethic and an appetite for learning, making him an exciting player of the future.

David Myers: A series of niggling injuries over the pre-season has been annoying for Myers and the Bombers, but shouldn't impact the start of his season too much. The 25-year-old is an important player for the club, with his booming left-foot and power at the contest making him a unique midfield option for coach James Hird. Few at Essendon get the distance with their kicking like Myers so they need him in full flight.

Brent Stanton: A veteran of Essendon's midfield, Stanton continues to be a strong pre-season performer. The 28-year-old remains near the front of the group in time trials, and is a hard trainer. He played every game last year and enjoyed another solid season.

Jobe Watson: After missing 10 weeks with his hip injury last season, the Brownlow medallist will be hoping for an uninterrupted run in 2015. He will captain the club for the sixth straight season and is a highly respected leader. The Bombers have built their midfield around Watson in recent seasons, and although less reliance falls his way, he remains the club's best and most important player.

David Zaharakis: Zaharakis sent a shiver down the spine of Essendon officials when he hurt his knee at a training session weeks ago, but the medial ligament damage was minimal and he's on track for being fit for round one. After a relatively quiet start to last season, the speedy and skillful midfielder had a purple patch in the middle of the year and showed his class. A vital member of Essendon's on-ball brigade due to his goalkicking nous. - Callum Twomey

FREMANTLE

Jacob Ballard: Powerfully built midfielder who spent last year racking up possessions in the WAFL for Peel. Has the frame to walk into AFL football but remains on the rookie list for now. Has had some lower leg issues this pre-season and is still doing conditioning work away from the main group.

Michael Barlow: Consistent reliable midfielder and key component of the Dockers side. Was having a good pre-season until he hurt his right ankle in the first NAB Challenge game against Melbourne. The severity is unknown but he missed training on Wednesday.

Connor Blakely: Impressive youngster who has been likened to David Mundy in size and languid movements. Has shown incredible development during the pre-season and has mature body. Played only half a quarter in the first NAB Challenge game but he dominated a WAFL practice match last weekend.

Zac Clarke: The ruckman started the pre-season with a knee issue but has worked his way through it and looks in fine shape. Has had a much better preparation this year than last season and there is a hope he can return to the form and athleticism he displayed in 2013.

Ryan Crowley: The veteran tagger has had an interrupted pre-season and continues to be managed. He did not play in the club's first NAB Challenge match and has not been named for the second. He ran laps at Wednesday's main session. Should be available for the start of the season but it is not guaranteed.

Matt de Boer: Endured a frustrating 2014 with a knee injury and poor form causing him to drift to the outer after being a fixture in the side. Signed a one-year deal and has put in an enormous pre-season to try to regain his place as a run-with midfielder who can also play a defensive forward role.

Nat Fyfe: The AFLPA MVP and two-time best and fairest winner has added a couple of kilograms to his legs to become more explosive in midfield stoppage situations. Continues to work on his goalkicking and is determined to improve again. Suffered a slight hamstring strain and missed the first NAB Challenge match but is raring to go now.

Brady Grey: Young Tasmanian who has come late to football after playing elite soccer throughout his youth. Tenacious runner who impressed in the WAFL last year and was an emergency on three occasions before stress fractures in his back flared late in the season. Likely to get a chance this season but needs to work on his disposal.

Jonathon Griffin: Fought his way back from a knee reconstruction in 2013 but played just one AFL match and played the rest of the year in the WAFL. Has had a good pre-season and is putting pressure on Zac Clarke for the second ruck role.

Jack Hannath: Continuing his development behind Sandilands, Clarke and Griffin. Has been working on his forward play and running patterns during the pre-season. Will be a back-up option while the senior players are fit but is likely to play at some stage throughout the year.

Ed Langdon: Younger brother of Tom who is at Collingwood. Has been managed during his first pre-season at AFL level after hardly playing last year before he was drafted because of injury. Will spend the early part of the year developing in the WAFL.

Craig Moller: In his third year on the rookie list, the young ruckman played one game in 2013 but played more WAFL reserves games than WAFL league games last year. Will remain at Peel barring a spate of injuries to the ruck stocks.

Anthony Morabito: Was the feel-good story of 2014 when he returned to play three matches after three years on the sidelines. Had a huge knee scare in September and has not been able to get any continuity during the pre-season because of ongoing soreness. Has been trying to up his running loads recently. It is unknown when he will return to main training group.

David Mundy: Classy midfielder who is among the competition's elite players. May begin to spend more time across half-back this year where he started his career to ease his workload. Remains an important clearance player and will be at the coalface in big games.

Tendai Mzungu: Signed a contract extension during the summer. He is the club's best runner, consistently winning the 3km time-trial. Versatile utility who also spends a bit of time at half-back and can drift forward and kick a goal when needed. Important member of the side.

Lachie Neale: Took his game to another level in 2014, becoming a consistent ball-winner in the midfielder. Adds another element with his elusiveness and smarts around the contest and is used a lot as a linkman in transition. Has become a fixture in the Dockers' midfield rotation.

Clancee Pearce: Did not play much last year after a limited pre-season because of Achilles surgery. He has had a fantastic summer and was busy in the Dockers' first NAB Challenge clash against Melbourne. Can play a variety of roles through the midfield or in defence. Will be pushing for a permanent place in the first-choice 22.

Danyle Pearce: Has had a limited pre-season because of a couple of leg issues. Hasn't clocked up many kilometres but he has started run freely in the past couple of weeks. Still hasn't played yet and wasn't named to face the Sydney Swans. Will be touch and go for the last NAB Challenge clash, but should be OK for the season proper.

Aaron Sandilands: Has been managed through the pre-season but looks fit, strong and set for another good year following a fourth All-Australian selection in 2014. The coach is spruiking that he could play beyond this year and possibly next.

Tommy Sheridan: Fremantle's first-round draft pick in 2011 and is out of contract this year. Played just eight matches last year and none after round 13. Has had a strong pre-season to date. Gathered 11 touches in the first NAB Challenge game and gets his chance to press his case further this week.

Nick Suban: Started brightly in the first NAB Challenge match last week and the coach was impressed with his work. Hard-running midfielder with pace and an ability to kick goals. Hoping to go to the next level this season.

Colin Sylvia: Has not returned to Fremantle training since he was sent to Peel Thunder for failing to meet minimum standards. Only in the second season of a three-year deal. Will need a dramatic improvement in attitude and performance at training and in games with Peel before being welcomed back to Fremantle.

Lachie Weller: Talented youngster who has impressed during his first pre-season. Was a dominant force in Peel's first practice match last weekend and has been named in the Dockers' 29-man squad to face the Swans. Has worked closely with the senior midfield group all summer and could play senior football this year.  - Alex Malcolm

GEELONG

Jimmy Bartel: After stints at half-forward and half-back in recent seasons, Bartel is set to return to the midfield to add some hardness around the contest. The 2007 Brownlow medallist still reads the game better than most and his marking is a clear strength.

Josh Caddy: Set to use an impressive finals campaign as a springboard into this season. Now in his third year at Geelong, Caddy will be given every opportunity to cement himself as a consistent AFL midfielder. Aggressive at the contest and steps up in big moments.

Nakia Cockatoo: There is a fair buzz about Cockatoo down at the Cattery and for good reason. The club's first-round draft choice (No.10 overall) has electric speed and a great sidestep. A genuine chance to make his debut in round one against Hawthorn.

Jordan Cunico: The young draftee possesses excellent endurance and is a powerful kick. Has been training in defence and is likely to play off half-back in the early part of his career.

Mitch Duncan: Duncan is a running machine and importantly works both ways. He is a devastating finisher in front of goal and his link-up work through the middle of the ground is first-rate. An integral member of Geelong's side and a potential future captain.

Dean Gore: Along with Cockatoo, Gore was the most impressive draftee on the training track during the pre-season. He is solid over the football and has the body built to play early in his career. Look for him to play some senior games as early as this season.

Cameron Guthrie: Set to enter the next phase in his development, with Geelong intent on freeing him up to win more of the footy this season. Spent last year as a run-with midfielder after a couple of years learning his craft in defence. Regarded as a future club leader.

Brad Hartman: Has been given indefinite leave from the club to work through some personal issues. Hartman has played five games in his two seasons at Geelong.

George Horlin-Smith: Horlin-Smith was limited by a nagging quad complaint through the pre-season, but is fit again and ready to build on an impressive 2014. The 22-year-old thrives inside the contest, but he is also clever around goals.

Jarrad Jansen: At 19 Jansen is as solid as they come and has the frame to mix it with some of the game's bigger midfielders. Jansen's strength in the contest is often telling and 2015 could be his year to break into the senior team.

Steve Johnson: The star Cat continues to dazzle, and frustrate (at the same time), football watchers with his unique style. Johnson's match-winning ability is unquestioned and at 31 is still racking up plenty of the footy. A key to Geelong's finals hopes.

James Kelly: Spent last season as a small defender, but is preparing to move back into the midfield this season to improve the club's contested ball-winning ability. Kelly has shown his toughness and uncompromising nature throughout his career.

Padraig Lucey: The Irishman got a small taste of what playing in the AFL was like when he was part of the Cats' NAB Challenge team that took on Gold Coast in Townsville. Lucey is still developing, but the Cats see plenty of upside in the 203cm ruckman.

Hamish McIntosh: Missed last year's semi-final against North Melbourne with a knee complaint and has battled through the pre-season after surgery. Slowly working his way back, with the Cats to face a tough test in determining their preferred ruck set-up.

Tom Read: The former South Australian has been training with the ruck group, where the Cats see his mix of athleticism and aggressiveness fitting best. Has already established himself as a popular teammate at the Cattery.

Joel Selwood: A proven match-winner, a star ball-winner and one of the best captains in the AFL. Selwood does not have much more to add to his resume, although there is no doubt he will do his best. As competitive as they come and one of the best players in the League.

Dawson Simpson: Simpson has taken some small steps in his recovery from back surgery late last season, managing to turn out in the Cats' two NAB Challenge games. Simpson's height offers something for Geelong, but the club is likely to take a horses-for-courses approach to its big-man stocks this season.

Mathew Stokes: Stokes had a tremendous start to last season until an ankle injury slowed him up midway through the season. The 30-year-old has a habit of finding unmanned space out on the ground and continues to find the ball with ease. – Ben Guthrie

Nakia Cockatoo has already made a big impression at the Cats. Picture: AFL Media



GOLD COAST

Gary Ablett: He's now 30, but there is little doubt Ablett is still the best player in the game. The dual Brownlow medallist has taken a cautious approach to his rehab from the dislocated shoulder that ruled him out of the final seven weeks last season, but he will be right come round one. Has used his recovery time to be in the best shape of his career, clocking personal bests over 2km at training.

Harley Bennell: A minor pre-season calf injury has not slowed Bennell down. The silky-skilled West Australian missed a few weeks of training, but is back in full flight. Previously seen as an outside ball specialist with sublime finishing skills, Bennell stepped up big time in Ablett's absence last year and showed he could mix it with anyone around the contested ball.

Daniel Gorringe: Big year for the athletic ruckman who has failed to cement a regular spot in his four seasons. Gorringe asked for a trade in the off-season but has ended up back at the Suns, where new coach Rodney Eade has trialled him on a wing and in defence during the pre-season.

Mitch Hallahan: Stuck behind a plethora of superstars at Hawthorn, Hallahan has headed north after just six games in four seasons. He is a strong-bodied inside midfielder, and although not blessed with great speed, knows how to find the ball. Hallahan is expected to do a lot of the inside grunt work to ease the burden on Ablett, Swallow, Prestia and O'Meara.

Jesse Lonergan: The energetic Tasmanian has struggled for a slice of luck in his first two seasons, suffering two broken hands and two torn hamstrings. He rolled an ankle in the pre-season, but has bounced back and is on the fringe of senior selection.

Jack Martin: An uninterrupted pre-season has the prodigiously talented West Australian in ideal shape for his second year. He is stronger and fitter, which is a scary thought for opposition players and coaches. Martin is still lightly framed but is strong over the ball, spring-heeled and has exquisite skills on both sides of his body. Watch for him to mix time between half-forward and the midfield.

Tom Nicholls: A PCL injury interrupted a promising 2014 for Nicholls and now he is in a dogfight with Zac Smith for the No.1 ruck role. Extremely talented around stoppages, Nicholls is also good once the ball hits the ground.

Jaeger O'Meara: O'Meara had surgery to both knees late last year, disrupting his pre-season. However, the 21-year-old is as diligent as any player on the Suns list. Is expected to play the final pre-season match and be available for round one.

Dion Prestia: After an outstanding past two seasons, Prestia can be relied upon for the same output most weeks. Like many of his teammates, had a slightly interrupted pre-season with back and hamstring niggles, but will be right to go against Melbourne in the first game. Mixes pace and outside dash with a hunger for the inside ball.

Andrew Raines: Given a lifeline after being delisted by the Lions, the professional Raines has been recruited as a mature rookie to help add depth to the inexperienced midfield. A PCL injury has derailed his pre-season, and while Raines is primarily expected to add guidance at NEAFL level, he can also step in and do a job for the seniors should he be required.

Michael Rischitelli: Finally over his injuries, Rischitelli revived his flagging career in 2014. He played 21 games, averaged 19 disposals and was a beacon of consistency. Still a valuable contributor with his ability to absorb punishment around the contest, win the contested ball and use it well off both sides of his body.

Luke Russell: Seemingly fell out of favour last season, but Russell has overcome a hip injury and will be in consideration for the starting 22 again. Might have slipped down a few notches in the pecking order, but has good speed and a thumping kick. At his best is another quality outside runner for the Suns mix.

Alex Sexton: Had an excellent pre-season and thrown his name right into the mix. Looks composed in traffic and has good speed and agility, so don't be surprised to see Sexton get some chances early in the year.

Matt Shaw: Another who had a patchy 2014, Shaw struggled to string good games together. He is on the fringe of senior selection, but runs hard both ways and is best used on the wing where he can utilise his excellent endurance.

Zac Smith: If his first NAB Challenge outing against Geelong is any indication Smith looks a new man. Dogged by injury over recent seasons, the athletic ruckman appears to have found the long sought-after aggression the coaching staff and supporters have been waiting to see. If Smith can produce that physicality on a weekly basis, it will help his push to be the No.1 ruckman and his team's push to the finals.

David Swallow: The former No.1 draft pick won his first best and fairest last year after a magnificent season. Swallow has always been a courageous inside player, but in 2014 began to get more on the outside, where he could use his blistering acceleration and improving skills. An uninterrupted pre-season leaves him in good shape for a repeat performance this year. - Michael Whiting

GREATER WESTERN SYDNEY

Jake Barrett: An outstanding runner who is eyeing off a senior debut after an uninterrupted pre-season. Impressed at NEAFL level last year, averaging 25 disposals. Is developing as a defensive midfielder.

Tomas Bugg: Boasts outstanding endurance, enabling him to be deployed in negating roles as well as other roles in defence. Finished third and fourth in GWS' pre-season time trials and will be looking to step up after his fourth pre-season.

Stephen Coniglio: Has had an extended pre-season after a broken thumb sidelined him for the final six rounds. Injury has dogged his career to date, but the out-of-contract West Australian's ability is obvious. Tagged Ryan Griffen with impressive results during an intra-club.

Tim Golds: The athletic 191cm midfielder wore the green substitute's vest in his three games and played mostly on a wing last season. Showed encouraging signs in the NEAFL and will be pushing for more game time this year after re-signing in December.

Toby Greene: Ball magnet who bounced back from off-field issues in phenomenal style late last year. The workhorse re-committed to the Giants until 2018 and looms as a key player in GWS' emerging on-ball division.

Ryan Griffen: Dispelled summer rumours of more back issues with a scintillating display in the NAB Challenge opener. Griffen has said he is refreshed after falling out of love with the game and his presence is sure to take the heat off his younger teammates.

Rory Lobb: Developing ruckman who played two matches last season and showed promise before a knee injury sidelined him for five weeks, which delayed his start to pre-season. Vying for second ruck spot, has filled out over summer and can take a mark up forward.

Shane Mumford: Winning the club champion award, the Kevin Sheedy Medal, in his first season showed the big ruckman's importance to the young Giants. Mumford's physical presence makes the midfielders around him walk taller. Crucial to Leon Cameron's plans and is feeling the best he has in five years.

Andrew Phillips: Has endured a frustrating two seasons with injury but has impressed over pre-season. Led the ruck in the Giants' NAB Challenge opener and is looking to return to his 2012 form.

Tom Scully: Came back post-Christmas and blitzed the time trial, but has been hampered by an ankle injury since February. The running machine is listed as two weeks away from returning. Should benefit with some pressure lifted from his shoulders after Ryan Griffen's arrival.

Dylan Shiel: Blessed with an exciting mix of speed and endurance, Shiel has taken his running ability to another level over summer. Looms as a key figure in a dangerous midfield.

Jacob Townsend: Is on crutches with bone bruising in his foot, which he suffered in the opening NAB Challenge match. The defensive midfielder's slight setback will sideline him for about a month.

Adam Treloar: A standout over pre-season, the rising star has continued his brilliant form from 2014. Has been tearing up the track alongside Dylan Shiel and Devon Smith.

Callan Ward: Led the young Giants superbly last season and was named in the All-Australian 40-man squad for the first time. His load should be lightened considerably with his old Western Bulldogs teammate Ryan Griffen taking more of the opposition's attention. Could go to another level.

Lachie Whitfield: Smooth-moving on-baller who had a delayed start to pre-season after foot and shoulder surgery. Is fighting fit and looking forward to a big year. Highly rated within the club.

Sam Schulz: Battled minor niggling injuries over summer. The rookie had a broken rib towards the end of last season and is yet to have a clear run at establishing himself. – Travis King

HAWTHORN

Jed Anderson: Ready to explode after a year ruined by a shoulder injury. The silky on-baller has had a tough run of luck in the past 18 months but has completed a huge summer program and should push for a round one berth. A leading light among the next generation of Hawks mids.

Jonathon Ceglar: Was desperately unlucky to miss out on last year's premiership but that heartbreak should drive him throughout 2015. Is an excellent tap ruckman and appears ready to assume the No.1 mantle with David Hale and Ben McEvoy spending more time in attack. 

David Hale: Veteran ruckman whose accurate kicking and strong marking up forward makes him a valuable member of Alastair Clarkson's flexible outfit. Likely to be managed this year in partnership with McEvoy and Ceglar, but he's a proven big-game performer and should be right in the mix come September. 

Jared Hardisty: The West Australian rookie has impressed with his attack on the ball, clean skills and big engine. Can play forward but will be hard pressed to earn a senior debut this year in a midfield stacked for options. Shows plenty of promise. 

Billy Hartung: Blessed with a rare mix of pace and endurance, Hartung impressed in seven games during his debut season before suffering a serious elbow injury. Has been one of the standout performers on the track this pre-season and is one of the fringe Hawks who will be knocking on the door of the best 22. 

Bradley Hill: A budding star of the competition. Hill took his game to another level last year, particularly in an outstanding finals series where he averaged 24 touches and nearly five inside 50s. Forms part of a devastating running combination with fellow wingman Isaac Smith.

Luke Hodge: Entering his 14th season, the inspirational skipper remains at the top of his game. Has been fighting fit over summer after playing 22 games last season across half-back, through the middle and at times in attack. If he's not Hawthorn's most important player, then he's in the top two with Jarryd Roughead. 

Will Langford: The former defender developed from fringe tagger to attacking weapon in a stunning transformation last year. The premiership hero's breakout year paved the way for the younger Hawks seeking to establish themselves in the best 22. Has added goalkicking prowess to his ferocious attack on the ball.

Jordan Lewis: Looms as possibly the next Hawthorn captain after a career-best season yielded the Peter Crimmins Medal in a premiership year. Has built his engine significantly to spend most of his time in midfield, although he can still be used at both ends if needed. 

Ben McEvoy: Rode the bumps of injury and form struggles to become a premiership player in his first season after crossing from St Kilda. Blessed with an enormous engine for a big man, he is seeking to improve his forward play and hit the scoreboard more often next season.

Sam Mitchell: The midfield generalbounced back from a hamstring tendon injury mid-season to be at his absolute best during finals. Was a standout at the Hawks' pre-season camp on the Sunshine Coast and is showing no signs of slowing down on-ball or across half-back. 

Jonathan O'Rourke: Made the bold move to Hawthorn from GWS knowing he will have a fight on his hands to nail down a midfield spot next season. His longer-term prospects look good as the Hawks deal with generational change in midfield. Can play a variety of roles, including on a wing or across half-forward.

Marc Pittonet: One of only two ruckmen picked up in last year's NAB AFL Draft. Is a confident and competitive footballer who, like all big men, will need plenty of time to develop in the VFL this season.

Liam Shiels: Tough-as-nails competitor who earned his second premiership medallion after playing with a broken nose in the Grand Final. Captained the club when a host of senior players sat out the NAB Challenge opener. Set to continue developing as a leader and in a more attacking role after excelling as a run-with player. 

Jonathan Simpkin: Played 18 games and was unlucky to miss out on a second flag last year. Showed a knack for influencing matches as the sub coming on in the third or fourth quarters with his zip and willingness to get his hands dirty. Will face hotter competition for spots as younger players continue to develop. 

Isaac Smith: Line-breaking wingman retained his crown, just, from Billy Hartung in the 2km time trial over pre-season. A crucial link-up man from defence to attack, Smith is among the absolute elite runners in the competition but is also developing his inside game.

Brendan Whitecross: Almost ready to resume for the first time since the 2013 preliminary final. Whitecross experienced slight soreness in his reconstructed knee pre-Christmas, but has looked in tremendous shape over pre-season and is closing in on an emotional return. 

Alex Woodward: Enjoyed a dominant season in the VFL in 2014 and was duly rewarded with the Liston Trophy as the competition's best player. Woodward, who also broke through for two senior games last year, has done his developing at Box Hill and is ready to go when the chance comes. - Travis King

MELBOURNE

Angus Brayshaw: The talented junior will need time to adjust to the rigours of AFL football. He started the pre-season well but has battled since a recent bout of gastro. Brayshaw has shown class on the track but he is likely to be introduced gradually.

Daniel Cross: Cross exceeded expectations after crossing as a delisted free agent. He was crucial to the team's competitiveness in 2014 before fracturing his leg against North Melbourne. The warhorse inspires teammates with his ability to push through pain, He has also proved a great teacher of young players. Injury-free, he will be a solid contributor once again.

James Harmes: The rookie-listed midfielder is good at the stoppages and capable of winning the contested ball. Had two good games at VFL level but remains a fair way off senior selection. Faces a big year. 

Max Gawn: Gawn has developed at a reasonable rate particularly given he has overcome two knee reconstructions in his career already. If he continues to progress he should emerge this season as a dangerous ruck/forward. He is mobile, a good mark and dominates the VFL. Just needs a consistent run free of injury to become a permanent senior player.

Matt Jones: To have managed 42 games in his first two seasons since being pick No.52 in the 2012 NAB AFL Draft is a credit to both Jones and the Demons recruiting. As the club finds more depth in its midfield, Jones will find it harder to get a game but he has not put a foot wrong yet. He has good pace, a great work ethic and runs to support but his kicking needs work.

Nathan Jones: Three consecutive best and fairest awards indicates how good Jones has been in the past three years. With more support now, his job will be as much developing the next era as continuing his form in the same vein. Ideally Jones will keep tracking at the same rate while being challenged for supremacy as the club's No.1 midfielder in the next couple of seasons.

Mark Jamar: If Melbourne could get Jamar to produce what he showed at times in 2014 on a more consistent basis then its midfield would improve immeasurably. At his best, he competes at stoppages and pushes forward to kick goals. However he needs to influence the game more to maintain his standing as the club's No.1 ruckman.

Max King: Has talent but needs to lift his intensity. Played a NAB Challenge game in 2014 but injuries derailed his development. He remains a project player.

Jordie McKenzie: Great clubman but has dropped off the pace under Paul Roos after an injury-interrupted season. He is a stopper but has battled with the need to move the ball quickly as his disposal has always been an issue. This season is crucial for the 24-year-old.

Viv Michie: Could play as a defensive midfielder or across half-back depending on where he is required. Michie wins the ball and uses it well. He won the confidence of teammates and coaches towards the end of last season and should build on that effort.

Alex Neal-Bullen: The inside midfielder has been in rehab since hurting his hamstring at the club's training camp on the Sunshine Coast. Has senior experience with Glenelg but will need to build his fitness before making a claim for a senior spot.

Ben Newton: Good left-foot kick and an industrious player, he battled injury than struggled for opportunity with Port Adelaide. He has class, a strong work ethic and if he can stay injury-free will receive enough opportunities to prove his worth in the midfield.

Christian Petracca: Ruled out for the season after a knee reconstruction following an ACL injury at training. He was making good progress so it was disappointing but the club has already laid plans to ensure he is ready to go this time next season.

Aidan Riley: Riley is a strong bodied in-and-under player who impressed upon his return from a nasty broken leg. He can explode from stoppages and holds his form. Remains in a battle for a midfield spot with three or four mid-range teammates.

Jake Spencer: Carries a huge heart into every game and contest. He is not blessed with skills but he competes with an intensity that midfielders love, creating room for them to win the ball and having opponents aware he is around. He has not given up hope of becoming the permanent ruckman and nor should he as he is predictable and doesn't let anyone down.

Billy Stretch: A surprise packet, Stretch doesn't appear far away from senior selection having trained well and bulked up over summer. Stretch is agile, has good pace and carries a bigger frame than his father, Steven, did when he played for Melbourne.

Jimmy Toumpas: Has disappointed in his first two seasons but showed positive signs in the first NAB Challenge game. He was at least busy and although things didn't go his way, he persisted. It's important he keeps a positive frame of mind this season as it will be two steps forward one step back as he regains confidence.

Jack Trengove: Another operation to repair his troublesome navicular injury has put the season in jeopardy however he will work hard to return. A popular figure at the club, he has moved out of the moonboot and his most recent scan was positive. Of course, a question mark remains over his long-term future but his talent (even though we haven't seen his best since 2011) and application is not in doubt.

Dom Tyson: An outstanding player, he emerged in 2014 as one of the game's most promising midfielders. Brilliant at finding the ball in tight he seems to find time to make good decisions. His kicking lets him down occasionally but it's a minor quibble. He kicked 16 goals to be second in the club's goalkicking and was a shining light. At 21, he shapes as a 200-game player for the Demons.

Jack Viney: The bull-at-a-gate style is Viney's strength and he has no intention of tempering it, however, he is working hard with senior assistant Simon Goodwin to find ways to win more uncontested possessions. Hard to believe he is entering just his third season but his relative anonymity now is an indication that Melbourne is improving.

Aaron vandenberg: Impressed in the opening NAB Challenge game when he came on the ground in the third quarter. Solid, aggressive and competitive, he looks ready to make an early impact.

Bernie Vince: A shoulder injury followed by a hamstring strain means Vince will go into the season slightly underdone. His experience means he can pick up the pace quickly after performing well last year but it also lowers expectations on what he might deliver early. A good player, he gives the midfield cheek and provides strength at stoppages. - Peter Ryan

PORT ADELAIDE

Brendon Ah Chee: A big midfielder who has taken a long time to develop and has been held back by injury. He has been fit this pre-season and knows he has to perform. Needs to find consistency in 2015.

Karl Amon: His stellar pre-season has drawn big praise from coaches and teammates and he would be odds-on to make his AFL debut this year. Fast, hard-working and with nice skills off a wing or half-forward.

Travis Boak: The skipper has enjoyed another great preparation for the season. He is the complete package and has won back-to-back All-Australian honours. One of the League's top players.

Sam Colquhoun: Will return from a knee reconstruction soon and hopes to pick off from his promising start. He is a natural – he knows how and where to find possession and uses the ball well.

Kane Cornes: The veteran's form seems to be defying nature – he ran a personal-best 3km time early in the year and was one of the best against West Coast last Sunday. He will play an important role in 2015.

Brad Ebert: One of the competition's premier hard-ball winners, Ebert's close-in work often sets the Power up and he is the hardest running player at the club. Had shoulder surgery last year but has trained fully all summer.

Billy Frampton: The draftee ruckman got a taste of the training load expected of AFL players before being struck down with injury. He had surgery on his shins and faces a delayed start to the SANFL season.

Hamish Hartlett: Has found the consistency in his fitness missing early in his career and his form in the past two years has flourished. A great pre-season endured a slight hiccup last Sunday when he injured his groin but he will be back for round one.

Matthew Lobbe: Coming off a tremendous 2014 campaign, Lobbe's pre-season has him perfectly positioned to push his claim as one of the AFL's best this year. He will spend more time in attack and rotate with Patrick Ryder.

Kane Mitchell: A much-loved character at the club whose work-rate and speed make him a highly valuable midfielder. Another player who has not put a foot wrong this pre-season and would hope to build on his 10 games in 2014.

Andrew Moore: When Moore is fit and has worked his way into form he picks himself. His combination of inside power and outside finesse is hard to find. He played well against West Coast and is on track to secure a place in the team.

Jared Polec: To his credit Polec has turned his career around since joining the Power from the Brisbane Lions. His run and carry, as well as his ability to kick long goals with his left foot, is a huge asset.

Jarrad Redden: Will make his return to the senior team on Saturday for the first time in 651 days. The ruckman has worked harder than anyone on Port's list to overcome a horrific run with injury that began in 2013.

Patrick Ryder: The high-profile recruit has looked in ominous touch at training since joining the Power. Won't feature in the NAB Challenge but if he is available come round one he will make Port tough to beat.

Johann Wagner: Won his way on to Port's list through a reality television program but his work ethic and training has shown he deserves his place. Runs hard and uses the ball well.

Matt White: Enjoyed a brilliant first year with the Power last season and his good work has continued through the pre-season, although he had a quiet game against the Eagles at Norwood Oval last Sunday. His speed and outside skill makes him an important cog.

Ollie Wines: He trimmed down in the off-season break and has worked tirelessly over the pre-season to be in the best shape of his life. The 20-year-old is on track to become one of the League's dominant midfielders in 2015.

Aaron Young: He has genuine ability and has proved so on multiple occasions but is yet to lock his place in the starting team. His terrific game against the Eagles reflected his training over summer. - Harry Thring

RICHMOND

Matt Arnot: The Tigers have been impressed with how the 21-year-old has responded to being moved on to the rookie list, noting a change in his training intensity this summer. Booted two goals in the opening NAB Challenge match. 

Daniel Butler: Drafted as a midfielder and a forward, Butler will be used primarily in attack in his first season. Played half a game against the Western Bulldogs and impressed with his speed and tackling intensity.  

Reece Conca: Conca was the standout performer on the track before he had a knee operation in January. He could manage two pre-season games, with the Tigers keen to rotate him through midfield, half-back and half-forward roles.  

Trent Cotchin: Yet to feature in the first two rounds of the NAB Challenge, Cotchin is being carefully managed with hamstring soreness. The Tigers are not concerned about his availability for the season proper, however, and he could squeeze in one pre-season game.

Brett Deledio: Has been held back this pre-season for an ongoing Achilles tendon problem. However, the vice-captain was unveiled in the second round of the NAB Challenge and will take up a regular role across half-forward. 

Nathan Drummond: Recruited as a midfielder, Drummond is likely to settle in the backline in his first season after spending most of the summer with Ben Rutten's group. Suffered some pre-season niggles but was ready for the Tigers' first pre-season game, winning nine possessions.  

Brandon Ellis: Has completed more pre-season work than any midfielder, leading the club's time trials and setting the bar in all aspects of training. Continues to work on becoming a duel inside-outside threat. 

Corey Ellis: The No.12 draft pick arrived at Punt Road with a foot issue and had surgery late last year. Returned to full training in March and is unlikely to be rushed into AFL action.   

Nathan Foley: Hasn't been able to get any consistency in his training, having a knee cleanout before a recent foot injury that sidelined him for up to nine weeks.

Shaun Grigg: Earmarked to help the Tigers' inside midfielders in an expanded ball-winning role. Has the size and toughness to play a contested game and has recovered from a plantar fascia injury earlier in the pre-season. 

Shaun Hampson: After a full pre-season, Hampson was one of the Tigers' best in their opening NAB Challenge match with 38 hit-outs. Has been challenged to win more possessions and has enjoyed an even battle in training against Ivan Maric. 

Taylor Hunt: The former Geelong tagger was one of Richmond's best in its opening NAB Challenge match, winning 18 possessions. The Tigers don't want him to be a tagger and are hopeful he can thrive on a wing after running second in time trials all summer to Brandon Ellis.

Kane Lambert: Showed his ball-winning ability in the opening NAB Challenge match, making a strong case for elevation off the rookie list. A star in the VFL, he has adjusted quickly to AFL demands and has been the surprise packet of the summer.

Ivan Maric: The No.1 ruckman started pre-season early alongside the Tigers' young players after avoiding off-season surgery. He has enjoyed an injury-free run, benefiting from a more tailored training program. 

Dustin Martin: After a more consistent 2014 season, Martin has focused on building his engine to increase his time in the midfield. A weapon when forward, he has also been challenged to win more contested ball in the midfield and run smarter.

Matt McDonough: Earned his seven senior games last year as a running defender but starred in the VFL later in the year as a half-forward. Going into his third season, the Tigers are looking to settle him in the midfield based on his solid clearance and contested possession numbers when used there. 

Connor Menadue: The Tigers will be patient with the No.33 draft pick, whose priority will be to fill out after joining the club weighing 69kg. An elite endurance athlete, he has spent more time on the track than any of the club's first-year players.  

Anthony Miles: A revelation in the second half of 2014, the former rookie has not lost any momentum going into this season, starring on the track. He shapes as a key player for the Tigers in 2015, starting the new campaign with 23 possessions and five clearances in the Tigers' opening NAB Challenge match. 

Ricky Petterd: Has settled in the midfield group, spending an entire pre-season with one line for the first time at Punt Road. Had 15 possessions in the opening round of the NAB Challenge, with the Tigers excited about the toughness he can add to the midfield.  

Ivan Soldo: The former basketballer is still learning the game in his first pre-season at Punt Road. A non-registered category-B rookie, the ruckman will spend most of the season in the TAC Cup.

Matt Thomas: Had a knee operation at the end of last year and is just returning to full training. Has the best skinfolds at the club and kept himself in top condition through his rehab, so could feature in the final NAB Challenge match. - Nathan Schmook

ST KILDA

Blake Acres: Has been tried on the wing and across half-back over summer. Entering his second season having worked hard over the summer and looks to have overcome the muscle injuries that plagued him last season behind him. With a decent pre-season, will push for more games this year.

David Armitage: One of the senior midfielders with the retirement of Lenny Hayes. Has had a flawless pre-season, is well and truly over the infected left knee that cut into his 2014 and has led the way over summer with the way he has trained. Will be important this year on-field and in a leadership perspective as the midfield evolves again.

Jack Billings: Had been having a strong pre-season until hamstring soreness in the warm-up before the Brisbane Lions' NAB Challenge game turned into a tear in the first quarter. Will miss another three weeks but the Saints are optimistic he w'll play round one. Expected to push through the midfield more this year with his improved endurance.

Luke Dunstan: Had a slow start to the pre-season after a shoulder reconstruction in August last year. Had been fully training since the middle of January before a rolled ankle disrupted him again. Played in the Saints' second NAB Challenge game and is likely to get more midfield responsibility with Sebastian Ross and Farren Ray out for a while,

Tom Hickey: Had right knee tendinitis operated on in London in August and has recovered well, having done plenty of work on his running and general fitness. Looked OK against the Bombers and is expected to play against Hawthorn. Is the most versatile of the big men, given he can push forward or back when needed.

Jason Holmes: Despite little experience with the game, has improved to the point where he could be considered for rookie elevation ahead of his second season. The US-born college basketballer has shown a good understanding of ruck work and continues to develop his skills in kicking and handball.

Billy Longer: Has improved over the pre-season and shown strong ability in the ruck but still needs to work on how he plays around the ground. Still young at 21, will keep working on his fitness as he competes with Hickey for the No.1 spot.

Daniel McKenzie: Young midfielder who can play on the wing or across half-back. Has shown good speed and kicking skills, and has picked up the game plan well since arriving in November. Missed a week with migraine issues but is back training now. Could play later in the season.

Leigh Montagna: Continues to be durable over summer and has put in a strong pre-season uninterrupted by injuries. Will lead the midfield as the oldest player in there (and is in the leadership group again), and will continue to mentor younger players this season.

Brodie Murdoch: The left-footed utility is struggling with a lower back injury that has cut into his pre-season and there has been no timeframe set on his return to the field. Won't be rushed, given his age and with the injury affecting his hamstrings at times, and the Saints are continuing to explore ways to get him fit.

Jack Newnes: Will look to play an inside midfield role and on the wing this year but also has the versatility to move from half-back to half-forward. Is extremely fit and looks to have improved again after playing all 22 games last season.

Lewis Pierce: Missed a lot of last season with stress fractures in his back but has had a decent pre-season off the back of a run of games in the second half of last year. Is considered a project player and is expected to continue to develop around the ground this year.

Farren Ray: Will miss nearly three months with a hamstring tendon injury that needed surgery after the Lions' NAB Challenge game. Was working on being more of an inside player this season and will get his chance to do that when he comes back. Will mentor young players as he gets himself fit.

Sebastian Ross: Rated as the Saints' biggest improver over the pre-season, will have to wait to strut his stuff after suffering a hamstring injury against Essendon. Had surgery and will miss 12 weeks. Has improved his strength, which will help him as an inside midfielder when he comes back.

Jack Sinclair: Has been impressive since arriving as a rookie and could push for promotion before round one. Is a year older than the draftees and is physically developed, and could give himself the chance to play after impressing against the Bombers.

Jack Steven: Has spent the summer working on how to cope with being tagged, as well as developing his leadership. Will look for a more consistent year after he struggled early last season following a February foot fracture. A key member of the Saints' engine, he will want to get back to his best form after finishing the season well last year.  

Eli Templeton: Has had a full pre-season after overcoming the broken arm he suffered in round six last year. Has been training with the midfielders in a bid to spend more time on the wing than at half-forward but will maintain the scope to play both roles.

Maverick Weller: His strong first season as a Saint led to his promotion to the senior list and appointment to the leadership group this year. Will play a similar tagging role this season but has worked on his offensive side and could cause an additional headache for his opponent. - Jennifer Phelan

SYDNEY SWANS

Craig Bird: Restricted pre-Christmas because of end-of-season knee surgery, Bird enjoyed a strong block of training in January and February. Has already been used in the NAB Challenge and will remain focused on playing a variety of positions this year.

Tom Derickx: The former Richmond ruckman played 12 games in 2014 and should feature again after a strong pre-season. The Swans have kept a focus on his ruck work this pre-season, reserving 20 per cent of his training for forward development. 

Jordan Foote: The Swans Academy selection was injured early in the pre-season with a stress reaction in his foot. Back in full training now, he is a couple of weeks away from playing games. Could yet end up being a defender.

Dan Hannebery: Presented in excellent condition after the off-season and came within two seconds of his personal best 3km time. Despite being best known for his elite running ability, Hannebery is a natural inside midfielder and worked more on that aspect of his game over the summer. 

Isaac Heeney: The Swans Academy selection has been managed in his first pre-season for knee tendinitis. Up and running now, the Swans hope he will show his class through the NAB Challenge and push for round one selection.

George Hewett: After suffering a knee injury in his first pre-season, the midfielder is getting solid hours on the training track this year. Good in traffic and a solid decision-maker, Hewett has also impressed with his ball use in training.

Kieren Jack: A steady pre-season for the co-captain, who has impressed the Swans with his ability to drive the club's younger players. With no injury issues all summer, he could potentially play all three pre-season games.

Josh Kennedy: After years building a revered fitness base, Kennedy was able to spend more time in game-specific training this summer. The Swans have hinted he could spend more time forward this year to add another dimension to his game.

Jake Lloyd: A revelation in 2014, coming off the rookie list to play 21 games, Lloyd is well poised to further cement himself in the Swans' best team. Has barely missed a session and is valued at the club for his neat ball use.

Harry Marsh: Heading into his third year, the midfielder has been challenged to break into the senior team this season and add depth. Drafted as an inside midfielder, he has enjoyed being used across half-back in match simulation training.

Ben McGlynn: After increasing his midfield time last year, the Swans are aiming for closer to a 50-50 split between McGlynn's forward and onball roles. A proven goalkicker, he battled a short calf niggle over the summer but has already played in the NAB Challenge.  

Jarrad McVeigh: The veteran has done most of his training with the midfielders and forwards, but the Swans are reserving the right to use him across half-back if needed. A minor calf injury held him out of the opening NAB Challenge match but he will play ahead of round one.

Tom Mitchell: The highly rated midfielder is primed for a breakout year after his first full pre-season. Has been a standout in training and is playing good minutes in the NAB Challenge, with the Swans also encouraged by his form when used forward in training.   

Sam Naismith: The rookie ruckman battled glandular fever at the start of pre-season but he is pushing close to full training now. A mobile big man, he can push forward and adds depth in the ruck if he performs in the NEAFL.

Toby Nankervis: A talented and hard-working ruckman, Nankervis has added a physical edge to pre-season training, regularly challenging his senior teammates. With a strong body and solid first season under his belt, he is ready to fight for senior selection.

Luke Parker: The 2014 club champion has barely missed a session this pre-season, which is extraordinary given the intensity at which he trains. Now seen as a weapon when forward, the talented midfielder will be encouraged to push forward where he can float across packs and take marks.

Lloyd Perris: The Swans academy recruit will be sidelined for the next two months as he recovers from another round of surgery on his troublesome left knee. Perris damaged meniscus cartilage on the knee he had LARS surgery on halfway through last year.  

Mike Pyke:  The Swans' No.1 ruckman is tracking well and will play long minutes through the NAB Challenge. Still showing improvement at 31, the Canadian is primed for a big year, according to the Swans. - Nathan Schmook

WEST COAST

Damien Cavka: The recruit made an impact when he broke Chris Masten's club 2km time-trial record this summer. Has extraordinary running power and wants to prove a point after being taken with pick No.66 in last year's NAB AFL Draft. Hasn't played in any of the club's pre-season matches yet and is likely to start in the WAFL with East Perth.

Brant Colledge: After impressing last pre-season he was on the radar to play some senior footy but ended up only playing two games. Had some ankle trouble late in the season. Played against Port Adelaide last week but had only seven touches. One of the players Adam Simpson wants to step up this year.

Liam Duggan: There is plenty of excitement around the Eagles' first-round draft pick but he has been carefully managed through the pre-season. Had a slight ankle issue that has kept him out of the first three pre-season games. Might be capable of playing senior football this year but may need to start well in the WAFL.

Andrew Gaff: Spent the past couple of years trying to learn how to cope with tags and started to gain some consistency. Has racked the possessions up in the first two NAB Challenge clashes. Could become damaging if he can kick some more goals from the midfield. 

Mark Hutchings: Has had a pre-season disrupted by a groin issue after fighting hard to gain a spot in the side last year and performing well when given a chance. Has the capacity to be a good run-with midfielder. The injury will mean a slow start to the year. 
Kane Lucas: Recruited as a mature-age rookie to add depth to the midfield stocks. Has played all three pre-season games to date and has shown glimpses in all of them. Could be elevated to the senior list as the Eagles have room given the retirement of Beau Waters and the injury to Eric Mackenzie.

Scott Lycett: Will shoulder a lot of the responsibility in the ruck this year along with Nic Naitanui. Took a step forward last year and was rewarded with a four-year deal. Can drift forward and kick goals and did that against Port Adelaide, bagging a couple of goals.  

Will Maginness: The young rookie has been dealing with stress problems in his lower legs all summer after the issues popped up late last year. The injury was untimely as he was performing well at WAFL level. Will be a slow year for him as he tries to recover.

Chris Masten: Given a leadership role this year and was the acting captain against the Indigenous All Stars. Remains one of the club's best runners and continues to work exceptionally hard on improving his kicking skills. The Eagles need him to have a big year.

Nic Naitanui: Enjoyed the best pre-season since 2012, only for back tightness to force him out of the first three pre-season games. The Eagles hope it is not serious and he has got the workload under his belt. Hoping to play against Fremantle in the last NAB Challenge.

Murray Newman: The Eagles stuck with him after he served his six-month prison term for grievous bodily harm last year. Trained all through the off-season break, only to suffer a couple of unfortunate knee and ankle problems after Christmas. Will have to work his way back via the WAFL.

Matt Priddis: The injury to Eric Mackenzie only places a greater burden on Priddis. He is the most important player at the club due to his ball winning exploits and he carries the midfield on his shoulders. Has dominated the two NAB Challenge games he's played. One of the competition's best inside midfielders.

Matt Rosa: The veteran signed a contract extension last year and has enjoyed an injury-free pre-season after tearing his pectoral muscle last season. Looks in great shape and may spend a bit more time across half-back than on the wing, but remains an important player when fit.

Scott Selwood: Had further ankle surgery in December that impeded his pre-season significantly but he has trained magnificently to get himself back and looks set to play round one. Might even play against Fremantle in the last NAB Challenge match. His leadership and toughness around the ball is invaluable.

Dom Sheed: Played 10 games in his first year and could be set to play all 22 matches this year. Had added some size to his frame over summer. Gathered 16 touches against Port Adelaide in the NAB Challenge and is capable of more. Can also push forward and kick a goal. 

Luke Shuey: Arguably the Eagles' most damaging midfielder and opposition teams know it. His speed and kicking can slice sides open, so he gets a lot of attention. Needs to work through that to support Matt Priddis. Will be important to the Eagles' prospects.  

Callum Sinclair: Has had an unlucky pre-season, with two nasty injuries to a finger and thumb sidelining him. Looked great against the Indigenous All Stars before breaking his thumb against Carlton. Will get back and push for the second ruck spot in the side. Should play plenty of senior football this year. 

Alec Waterman: Father-son recruit has had a good pre-season. Has shown a great running capacity as an inside midfielder despite being managed at a couple of points. Nearly played the last NAB Challenge match. Likely to start in the WAFL but strong performances will give him every chance of promotion.

Sharrod Wellingham: Has had a good pre-season and appears to be on track for a great year. He is in the final year of his contract. It is less about what he does with the football than what he does without it. Could play forward as well. The Eagles need him to stand tall.

Elliot Yeo: Has recovered from the broken hand that ruined his season last year. Will push more into the midfield after initially being recruited from the Brisbane Lions as a half-back. Showed some ability in clearance situations last year and can use his pace and kicking as weapons. - Alex Malcolm

WESTERN BULLDOGS

Marcus Bontempelli: Last year's NAB AFL Rising Star runner-up will be looking to build on his eye-catching debut season. Will be one of many young Dogs expected to step up in the midfield following the season-ending injury to Tom Liberatore

Matthew Boyd: There was talk that 2014 might have been Boyd's swansong, but the former skipper's knowledge this season will be invaluable for a club light on experience. New coach Luke Beveridge has indicated he will use the 32-year-old across half- back this season.

Tom Campbell: The developing ruckman played only seven games last season, but impressed with his ability to play in the ruck and up forward. Should challenge Will Minson as the team's No.1 ruckman in 2015.

Ayce Cordy: It looms as a make-or-break season for the fifth year father/son recruit. The once injury-plagued ruckman has played only 20 senior games, but former club captain Luke Darcy believes the 24-year-old has the ability to carve out a successful AFL career.

Luke Dahlhaus: With Ryan Griffen and Adam Cooney gone, the 22-year-old will get plenty of midfield time in 2015. Good in close and on the spread, Dahlhaus should revel in Luke Beveridge's attacking game plan.

Mitch Honeychurch: The fiercely competitive midfielder impressed in three AFL appearances in 2014, playing mainly as a high half-forward. But with the injury to Tom Liberatore and several veterans moving on, the 20-year-old should get plenty of midfield opportunities.

Nathan Hrovat: The diminutive playmaker is becoming an important part of this young Dogs side with his sure foot skills and sound decision-making. His preparation was interrupted by a rib injury in the opening week of the NAB Challenge.

Lin Jong: After impressing in three seasons on the rookie list the 21-year-old looks a likely starter in round one. Has a dangerous mix of power and speed but needs to work on his kicking and decision-making.

Tom Liberatore: The 22-year-old budding superstar will miss the 2015 season after injuring his knee in round one of the NAB Challenge. Teammates will have to lift to cover his loss.

Josh Prudden: The 20-year-old will be looking for a debut and some luck in 2015 after injuries ruined his first two seasons at the club. The creative inside midfielder could help fill the big hole left by Liberatore's injury.

Jack Macrae: The classy ball magnet averaged an impressive 26 possessions a game in 2014 to finish second in the Bulldogs' best and fairest count and poll the most votes for the Bulldogs in the Brownlow Medal (10). The 20-year-old looks destined to be a 200-game player.

Will Minson: The 2013 All-Australian will be desperate to atone for a disappointing 2014 campaign. The aggressive ruckman will need to get back to his best, with understudy Tom Campbell ready for more opportunities at senior level.

Clay Smith: The tough-as-teak on-baller is recovering from his second knee reconstruction in two years. The 21-year-old is ahead of schedule in his recovery, but the club is taking a cautious approach.

Roarke Smith: The long-haired rookie is likely to spend most of 2015 in the VFL with Footscray. The Dogs like the wingman's run and carry and penetrating left foot.

Koby Stevens: The solidly built inside midfielder needs to work on his awareness and decision-making, but is a threat pushing forward with his strong overhead marking and sound kicking.

Mitch Wallis: The Bulldogs will be hoping Wallis finds the consistency that has eluded him so far in four seasons at Whitten Oval. The 22-year-old should get plenty of opportunities due to his great mate Tom Liberatore's season-ending knee injury. - Ryan Davidson
