I think Dimma has a lot to do with it but once the players cross that white line they have to know what the stuff to do.
They are responsible on field, they should all step up and be leaders they can't let Dimma take all the heat.
Having said that, what ever speech or preparation Dimma and assistant coaches put into the team before the game is rubbish because they always come out in the first quarter like they've been asleep for decades and don't know wtf to do..
