I wasn't a huge fan of Kadri's decision; it was impulsive and selfish, and certainly isn't the first time he has put his desire for revenge ahead of the best interests of the team. As others have stated, there were other ways to deal with that, primarily, dropping the gloves. At least with that route, it wouldn't have put us out of a game we were still very much in, and he'd be around to help the team for the remainder of the series. Not to mention, this kind of behaviour is playing in to exactly what Boston wants. I wouldn't be surprised to see him get 5 games, as he is a repeat offender. Being one of only a handful of players on the team willing to throw the body around, he will be sorely missed.
As for the notion that the leafs organization should publicly shame the league officiating, I think that would not help their case at all, and ultimately, would hurt far more than it helps. I imagine that concerns will be voiced through private channels, as they should be.
