The Blades receive future considerations for giving up a guy with a knack for getting under the opposing teams skin. According to Hockey Fights, McJ is second only to Benn Olson in number of fights. He has been injured for some time. But, I don't see the point of this trade. Unless the Grizzlies have another player like Shea Guthrie playing, this is a dumb move. No other player on the team is as good at agitating opposing players, and not many guys are as willing as he is to drop the gloves.
His fights, this season and last, have led to many changes in momentum. It is so heartbreaking to see such an important piece of the team be traded away for virtually nothing. Hopefully the Grizzlies, and their fans, realize what they're getting.
