Forget holding the ball changing week to week, it changes game to game. I'll watch any game of footy and the difference between a Saturday arvo and Sunday arvo is astounding. That's the biggest problem. There shouldn't be an open interpretation of what a rule is. It should be clear cut. Go back 2-3 years. If you have prior, you're gone. Being swung 360 degrees is prior. Free kick. If you get sat on by 389587345 players, blow the ■■■■■■ whistle after a few seconds and ball it up. Don't wait 5-10 seconds and slow the play down.
On the Monfries one, well I can't blame the umpire really. I was fuming at the time but in that sort of game you're damned it you do and damned if don't and it goes back to what I said. With no clear cut interpretation, there's going to be errors and in that situation. On the same note, if it was paid and Mitchell was running into an open goal and it got called back, all hell would break lose the opposite side. You can't win.
