Unsportsmanlike for a play that had nothing to do with the game and no place in the game that could have potentially ended one of his players careers(there has been a lot less concussions that have ended peoples careers).
In my mind, this was a play to the point that you don't forgive the other player or the other team. it was completely unnecessary and uncalled for, especially in an exhibition game. Completely spineless by cormier and I agree with the Swedish coach, sends a message that people don't accept that, period, in the game of hockey. personally I am proud of the Swedish coach(and a lot of people will disagree with me) because he went against what most people would say is sportsmanlike, but Cormier crossed that line first. Also, in my mind what the Swedish coach crossed that line less than Cormier(potentially destroying a players career versus I didn't get a handshake, come on).
