I agree strongly with your last point. Kadri has been rocked quite a few times, some of them dubious as well.
At some point, you start to wonder (this has been said so many many times) when does the player who gets hit with his head down bear some of the responsibility. It's true his head bounced off the glass, but, that is only because Kadri hit him in the shoulder and he was standing beside the boards. If he's at centre ice his head doesn't hit the glass and he doesn't get his bell rung. I didn't see charging, didn't see Kadri jump up, didn't see him go for the head, didn't see his elbows come up, just saw a player finish a check!
