ADELAIDE coach Neil Craig has warned the jump in the number of interchange rotations seen in round one could contribute to more high-impact injuries, but says a cap is not necessarily the answer.

Last weekend five clubs set new records for rotations, including North Melbourne which made 139 substitutions to eclipse the previous mark set by Collingwood (131) in round 20 last season.

On Wednesday, West Coast coach John Worsfold stated he was in favour of capping the number of rotations a club could make during a match because the current trend was not in the best interests of the game.

Craig disagreed with Worsfold's view and said the number of rotations would eventually level out.

"It'll become physically impossible to get more people off the ground, otherwise players will only be on for 10 seconds," Craig said on Thursday.

"You have to understand that the time it takes to get someone off the ground is downtime in the play. There's going to be a tipping point where it's not worth doing anymore.

"More rotations mean guys are getting a greater rest period so the speed of the game goes up, which I think is exciting for the game. The players love playing in it because it's speed and it's action, but when you've got 90kg aggressive, six-foot-two people running around and the speed stays up, I think the concern for the AFL would be high-impact injuries.

"I'm not the keeper of the game, so it's not for me to make that call but purely from a coaching perspective and hearing players talk and football fans watching, they love it."

Adelaide had 34 fewer rotations than its opponent Fremantle last weekend, using the bench just 91 times.

Craig said there would have been more changes if not for injuries to Scott Stevens (concussion) and Rory Sloane (ankle).

"We probably would have made 100 to 105 rotations and that's up for us. We're following the same trend and each year we've gone up.

"We've tended to be in the bottom eight teams in terms of the number of rotations, but we're still going up."
