Id have to say the hit was dirty. Regardless of what VanRyn did to "fool" TK (even if he decided to go around the net, would TK have just continued full throttle into the boards then? Doubt it.) It such a common play (chasing the puck in to the boards) that those types of hits would happen 5 times a game, every game, if the attacking forwards didnt know to stop themselves, or at least let-up a bit. Honestly, Id say the same thing if the roles were reversed.
