I heard via the rumour mill that Aaron was demanding to be played more. And that his agent and father were also harassing MG. I have no evidence of this but Gillis hasn't denied it either so it must be true.
He didn't want to be here. No one liked him. He was a prima dona and had to go. His replacement Pinizzotto, even though he's only played like 16 games in the last two years and makes Salo look like Iron Man, will be waaaaaaaaay better at the same role. We don't need no whiners.
