No doubt. If it were to be reduced to 12, the league structure would be something similar.pre Adelaide Oval thought Port Adelaide was in real trouble but since the move to AO Port is a lock
this thread is all hypothetical but if the league reduced to 12 teams there would 2 teams in Adelaide , 2 in Perth and 6 in Melbourne / Geelong with the Hawks playing some games in Tasmania plus Swans and Lions
But it never will reduce back to 12. Not one club would want to leave the cocoon of the AFL, even if it were for the health & benefit of the whole league. The media deal allows for 9 games per week. So that's that.
Given we have 18, as I've said, its silly to not have3 in WA & 1 in Tas. If that is only able to be done with a move to a 20 team league, then so be it.
