Collingwood has warded off a challenge from the Western Bulldogs to secure father-son prospect Darcy Moore with pick No. 8 in this year's NAB AFL Draft.

The Bulldogs, keen to bolster their tall stocks, bid for Moore with their first-round pick – pick No. 5 – at Monday's father-son bidding meeting, but the Magpies matched it.

This means the youngster will immediately join the Pies' list after the draft.

Moore, the son of premiership Pie and two-time Brownlow medallist Peter, is a 199cm key position player who has shown an ability to play at either end of the ground.

He played TAC Cup with the Oakleigh Chargers.

Moore was one of 12 players to make it to their nominated clubs at the father-son and academy bidding meeting at Etihad Stadium.

The Demons placed a bid for highly-touted Sydney Swans Academy member Isaac Heeney with pick No. 2 in the draft, but the Swans immediately matched it.

Some football watchers believe Heeney would have rivalled Christian Petracca as the top-rated midfielder in this year's draft had he been available in the regular pool.

North Melbourne also placed a bid on Canberra product Jack Steele (a GWS academy member) at its pick 15, but Greater Western Sydney trumped them by taking him at No. 23.

After missing out on Heeney, the Demons had some success when they acquired father-son selection Billy Stretch with their third-round pick (No. 39) after Adelaide bid with its 29th selection.

Stretch, whose father Steven played 164 games for the Demons, is a promising wingman who was named in the midfield in this year's NAB Under-18 All Australian side.

The Brisbane Lions locked away two club academy players, adding Liam Dawson and Harris Andrews to the club's 2014 squad.

Dawson and Andrews received bids from Richmond and North Melbourne respectively, but the pair will remain in their home state after the Lions matched the bids.

Western Bulldogs father-son prospect Zaine Cordy, the younger brother of Ayce, slipped to the club's fourth-round selection.

It was expected Cordy, the son of 174-game Bulldog Brian, may have attracted a bid inside the first 30 picks in the draft.

Joining Heeney at the Swans next season will be fellow academy members Jack Hiscox and Abe Davis.

Hiscox, who recorded a beep test result of 16.1 at last week's NAB AFL Combine, attracted a second-round bid from Fremantle but the Swans responded and will take the endurance machine with pick No. 37.

Geelong placed a bid with its pick No. 70 on Davis but he will also join the Swans after the club committed to taking him with selection 73.

The three remaining players – Josh Clayton (Brisbane Lions), Alec Waterman (West Coast) and Jeremy Finlayson (Greater Western Sydney) – will join those clubs with their last selection in the draft.

Note: Compensation picks are not taken into account in draft order

The son of Gold Coast list manager and former Fitzroy player Scott Clayton has been nominated by the Brisbane Lions, who would be attracted to his versatility and ability to read the game. An athletic 190cm prospect, he was used all over the ground with TAC Cup side Sandringham and Vic Metro this season and appears best suited as a lead-up forward who can move into the midfield.

The Geelong Falcons product is the younger brother of Western Bulldogs ruckman Ayce and the son of former player Brian, who played 124 matches for the club. A tall defender who excels one-on-one, Cordy stands 192cm and has good combination of natural speed and endurance. Uses the ball well and should attract a bid inside the first 30 picks.

Darcy Moore (Collingwood)
The son of Collingwood great and two-time Brownlow medallist Peter Moore is keen to join the Magpies, where he could be developed at either end of the ground having excelled as a tall forward and key defender this year. Boasting excellent closing speed, a natural leap, strong marking ability over his head and smarts around goal, the Magpies may have to use a first-round pick to secure the 199cm prospect as a father-son selection.

Billy Stretch (Melbourne)
The promising wingman has been nominated as a father-son selection by Melbourne, where he trained for a week in January and his father Steven played 164 games, winning a best and fairest. The South Australian, who can also add zip across half-forward, was named as a midfielder in this year's Under-18 All Australian team and he finished the season strongly with SANFL club Glenelg.

The son of dual premiership Eagle Chris Waterman has established himself as a versatile midfielder with a raking left-foot kick and leadership potential. Specialises as an inside midfielder and stood out against Vic Metro at the NAB AFL Under-18 Championships, winning 35 possessions (17 contested) and 10 clearances in a standout performance.

The tall forward/defender has played predominantly in attack this year after showing promising signs as a defender in last year's NAB AFL Under-18 Championships. Is a strong mark and good competitor who also comes with a degree of versatility. From the Sydney Swans Academy.

Nominated by Greater Western Sydney as an Academy selection, the 18-year-old midfielder will become the first Canberra player to be drafted since Jason Tutt in 2009. A strong onballer who can also play forward, he has excellent poise and balance and is an effective lead-up player, winning All-Australian honours as NSW/ACT's MVP in the NAB AFL Under-18 Championships.
