So the trade(the reason why he was included) was more for just freeing up contract for CAR?
Not really. It was a one-for-one contract swap with Westgarth going the other way. Carolina wanted added toughness, and the Kings wanted draft picks for Westgarth. They took Stewart so Carolina could clear a little cap space.
How bad is he?
Can he play 4th line effectively?
Red Wings need some size on bottom 6.
Maybe something like Tootoo - Abderkader - Stewart?
77 games played, averaged just over 8 minutes per game, and had 9 goals 20 points, and 30 PIM's. Seems like Carolina put him in almost every game last year on the hope that he might do something in that game, but when he wasn't bringing it, he was put at the end of the bench. Yet they continued to have him suit up every game. It's an odd stat line.
