No one has avery's history, except maybe Ron Artest. but still, the tone of the comments, personally directed at individuals by name. That would never pass in the NFL either. KG and pierce decided to take the high road and just refuse to comment.
I think if there had been ANY doubt (which was very little to begin with) about how he wasn't the "victim", he just exposed himself to going up to KG with an agenda. Coaches have gotten fined for far less about officiating. This takes it outside the game and made personal comments.
