Are you insane? After 121 years since 1897 you want a non contact sport and call it Australian Rules? You should be banned for life from even using the words Australian Rules Football. What is wrong with you? Overhaul what ? Any attempt at that BS and the AFL might find themselves overhauled...
They change rules, players adjust, change more rules players adjust, change more rules players adjust......and on and on. From year to year the game doesn't look much different but then you go back and watch a replay from 30 years ago and the game is completely different.
They won't specifically state in the rules that players must keep their feet but the subtle rule changes and umpire interpretations will make it so that players must keep their feet, if that's what the AFL want. The changes in the game from year to year are such that there will never be a fan revolt.
Anyway, that's my view on it.
