You just have to shake your head with the MRO and the tribunal really.
Last year, Broady picks up that Adelaide fella, swings him round (relatively slowly), but ends up planting his head into the turf - 4 weeks
Cameron does the same action, picks up Fists of Fury, swings him round and slams him to the ground (much quicker than Broad) but flukes it that his head doesn't hit the ground - 1 week down to zero because he's a good guy
Marlion - Gets a week for "potential to cause injury" because the AFL have determined he's not a good guy
Vlastuin - Barely a free kick on Butler, Butlers arms free, head doesn't hit the ground - here take a fine
Yeo - Tackles Vlastuin, neither hands free, slams him to the ground but doesn't hit the head - Christian - "what? was I supposed to be watching that, do I get to fine Vlastuin again?"
If 1 of these players gets seriously injured again but this time from a tackle, its going to be a free for all from all the lawyers wanting to prosecute, its going to be so easy to win the case, based on the AFL being so inconsistent in its approach that its doing nothing to protect for dangerous impacts to the head from tackles.
