Not sure about the incident with GRimes, didn't see it. But the Bennell one has been spoken about. He is just keeping his spot as it is. Batram showed him how to on the back flank yesterday. He doesn't play tight enough to be in the back line.
The main issue though is every week he gets off the train and it's horrible to watch. I've seen it at Casey and for Melbourne, opposition sides will have seen it and know if they go hard at him he will be looking around all game.
