I think Keating's tackle was ABSOLUTELY NOTHING.
At worst it was a 'careless chicken wing' - but without intent it is simply an accident.
He's just grappling with an enormous man, slips off the tackle but retains hold of his arm, and as other tacklers come to get involved, slips into an awkward position.
Nothing in it.
Irritates me that they give a penalty when they see that on replay, but don't give a penalty when Andrew Ryan clearly makes first contact with Gulavaos head.
Personally I think there was no intent in either, play on - but looking at the replay, the Ryan 'offence' is something that has been consistently penalised all season AND in the semis (Ben Smith got penalised for hitting ball first and sliding up...)
