Final 8: More exclusive (more than half of the teams making the finals would be outrageous) and the system in place at the moment is pretty fair.
24 rounds: Play every team once and 7 teams twice just like now. Not too fussed on this, however. Wouldn't like to go to 17 as it's too short IMO and highly doubt the AFL would agree to it with the less televised matches. Don't mind the idea of a season where you can play everyone twice but it's simply too long for a sport like Aussie Rules.
Abolutely no Supergoals: Tinkers with the scoring too much, the game is already confusing enough, if people want higher scoring games you can just change goals to 10 points and points to 3.
