COACH Dean Bailey says interchange rotations should not be capped or introduced into the game.

The topic has generated debate among the football community in recent times and the AFL is investigating whether limiting the number of interchange rotations per match should apply.

But Bailey said he was in favour of interchange rotations evolving, rather than placing restrictions on it.

“I’ve always had the opinion to just allow the market to determine what it is,” he said from Gosch’s Paddock during his weekly media conference on Thursday.

“I don’t think capping it or putting in restrictions is a great way to go, but I’m sure the research that they’re doing will come up with some definition at the end of it.

“The number [of how many interchange rotations] then becomes the issue and then how pre-season’s trained and how you train players will be affected by that.”

Richmond coach Damien Hardwick recently said the introduction of restricted interchange rotations could determine the future of some older players, for example Tiger star Ben Cousins.

But Bailey didn’t believe any such caps would alter the way Melbourne would recruit or retain players.

“If you want to mine really deep, you’ll find something, but I don’t think so,” he said.

“Their pre-seasons, the amount of GPS and the amount of information we know about players - the training regime reflects how you want to play the game. In my view, I don’t think that’d affect someone, if we had a Ben Cousins-type on our list.

“It’s more if they’re (the AFL) going to make a decision [on interchange rotations], when is the research going to be finished and when the research is going to be done - then you’ve got to define what’s been said. So we’ll evaluate that first.”
