And wht is this so called negative impact?
What is wrong with having a large number of interchanges????
LEAVE THE GAME ALONE,
I voted for the 2+2 cap on interchanges because whilst I think the injury reason is a furphy, fresher players are enabling teams to employ rolling zones and clog up space more efficiently, to the point where players run and bounce the ball only half as often as they did four years ago, while there has been a corresponding increase in tackles and congestion.

2009 182 29 124
2010 232 21 135
I'm not strongly in favour of the change because I don't know for certain that it will have a positive effect, but for all the perceived evils of the AFL I reckon cross-pollination with other sports has done a lot more damage.
