COACHES are not so self-interested they don't consider the wider interests of the game, North Melbourne coach Brad Scott says.

Scott told AFL.com.au coaches were football lovers at heart who had a vested interest in the game's future despite their focus on their individual teams.

The Kangaroos coach was speaking in the wake of controversy surrounding the trial of an interchange cap of 80 rotations in this year's NAB Cup.

Scott was among a number of coaches who raised concerns about the impending rule change, saying last week the cap could lead to clubs putting large numbers of players behind the ball if fatigue led to more open play.

Laws of the Game Committee member Kevin Bartlett hit back at the coaches' comments on SEN radio on Monday, saying they did not have "one single thought when they are coaching about what is good for the game".

Carlton coach Mick Malthouse meet with the committee on Wednesday to discuss his concerns over the interchange cap.

Scott said coaches could look beyond their teams' performances to give well-informed feedback on how proposed rule changes would affect the League.

"I think coaches are extremely well placed to respond to questioning about 'If we change this rule what would your response be as a coach?'

Coaches have a pretty vital role to play there," Scott said.

"Kevin [Bartlett] was once a coach himself and I'm sure he cared about the game then too, just as he does now. He's a passionate lover of our game, but no more so than other fans out there.

"And all coaches, you just wouldn't be involved in the game if you didn't love the game and want to see the game thrive and prosper."   

Scott said he had raised concerns about the proposed interchange cap despite knowing it could work in North's favour when it is introduced in the 2014 home and away season. The Roos were ranked 17th in average rotations (118) last season - an average 36 behind competition leader Adelaide - and, as such, would face an easier adjustment than most teams to any new cap.

"If you look at the stats and you look at where we finished last year in interchanges in the competition, do you think 80 would be better for us or worse?" Scott asked.

"It's probably better."

Scott stressed he agreed with Bartlett that it was not the coaches' place to make the rules, but said their feedback on what effect proposed rules would have was worth considering.

"All I've heard coaches say is that if there are changes to the game they will force a response," Scott said.

"If the Laws of the Game Committee and the AFL Commission change rules, they will force coaches to respond and all I'm saying is, that's dangerous when there's a natural evolution of the game anyway and if you force coaches to respond I'm worried that the Laws of the Game Committee will then respond again.

"Then you just go back and forth with responses and you end up chasing your tail."

AFL CEO Andrew Demetriou confirmed on Tuesday the AFL commission was already committed to introducing an interchange cap in 2014, but had yet to determine the appropriate number of rotations to allow.
