I’d actually give a tick to quite a few of them.
1 Centre bounce positions. Cross. Not needed.
2 kick-ins, no kick to self. Big cross. Stupid idea
3 No player within 10 metres of goal square at kick-in. Big cross. Another stupid and unnecessary idea.
4 Defender marks in goal square; man on mark brought out to 10 metres. Tick. It’s what happens already.
5 & 6 Runners and water carriers. Big tick. They’ve been a blight on the game for years. Collingwood’s runner-inflicted own goal in the GF was poetic justice.
7 Umpire contact. Cross. Unnecessary.
8 50 metre penalties a) defender not allowed to impede player with the ball - tick. Sensible. B) play on before new mark has been set - big cross. Chaotic.
9 Kicking for goal after the siren. Tick. What matters is where he kicks, not where he starts his run up.
10 Hands in the back. Tick. Hands in the back should never have been a rule anyway. Pushing in the back has always been a free kick.
11 Ruck contests - taking possession. Tick. Reverses a previous stupid rule change. Designated ruckman — big cross. The whole designated ruckman thing is ridiculous and this will make it more ridiculous.
Just btw, there are more like 13 rule changes, not 9. I wish someone would take Garry Hocking outside and shoot him. Every year these people come up with ideas that are poor solutions to non-problems. Of the ones I’ve given ticks, only the runners and water carriers rules are really new. Hands in the back and ruckman taking possession are simply reversing previous stupid changes, and the others either reflect the status quo or restate the current rule.
