Honestly how hard was it for the campaigner to simply say to north hey you don’t have any interchanges left you can’t have X player come off. Not hard and doesn’t ruin the game.I think the reason is obvious.. the guy who's job it is to count the interchanges on behalf of the AFL would've been creaming himself and waiting for them to exceed it, yearning for relevance. It's like a parking inspector standing by a meter with 6 mins left on it.
