If it was clearly intentional I would be pissed, but I think that it was just meant to be a good play taking the player out of the play. Hishion started to duck and McNabb nailed him. Had he not ducked it would have been a great shoulder hit Yes he deserved the penalty and misconduct because it was a hit to the head but no way do I think he did it intentionally to get him injured or out of the tournament.
Everyone is entitled to their own opinions but the ruling was made a long time ago now and its time to move on. Thats hockey and it happens to every team at some point of the year.
