COLLINGWOOD coach Mick Malthouse, one of the biggest users of the interchange bench, says suggestions to cap the number of rotations per match would not benefit the game.

Malthouse's club has helped set the trend for increasing rotations in recent years and he is yet to see any evidence supporting the view that higher numbers are proving detrimental.

Last year, Dane Swan was the most benched player in the AFL, finishing the season with the most disposals in the competition and winning Collingwood's best and fairest award.

West Coast coach John Worsfold raised his concerns earlier this week at the growing number of interchanges being made each game and proposed capping the maximum allowed per club per quarter to 20.

Round one saw numbers reach record highs with the interchange bench used, on average, 113 times by each club. That was a 25 per cent rise on 2009.

"[There's] no need for a cap," Malthouse said on Friday morning.

"There's not one indicator yet that's been put forward that states that the game is deteriorating, that players are more injured or the game is not a good spectacle because [of higher interchange numbers].

"I go and watch other games and quite frankly at the end of the game I don't say, 'Oh, there are 200 interchanges between both sides'.

"All I say is, 'I know who was out there' and interchanges are done in such a manner to suit the side.

"Generally by suiting the side, you are suiting the individual to perform at his best for as long a period of time at the football club as you possibly can.

"So all our indicators are [that] the correlation between high interchange [is] less injuries."

Malthouse also weighed into one of the other issues of the week: Good Friday football.

Collingwood trained on Friday morning as part of its normal weekly routine but Malthouse said playing a match on Good Friday would do away with past traditions - something he was wary of upholding.

"It's a dilemma," Malthouse said.

"I suppose the more and more you eat into them (traditions), there's no going back.

"So I'm half suspecting that if there is ever a game, [then] how do you recall it? How do you say, 'We're not going to have one there and why are we doing it?'

"I'm not convinced one way or the other but I'm certainly not worried that there's no game today."
