I think West Coast will have to go fairly deep into September if Gaff is going to play again this year. If you look at the precedent set by the Jeremy Cameron suspension for his hit on Harriss Andrews - the MRO and tribunal tend to put a lot of weight on the outcome of an incident rather than the intent. Given Brayshaw's season is done after that hit, Gaff is in real strife.
Having said that, it was pretty poor on Gaff's part - a behind the play hit 100m off the ball. He deserves whatever he gets really. If it happened in suburban or country footy, we'd be talking about whether or not he should be charged with assault.
