I can't really speak about Petersson, having never seen him play (or even bothered to look into the guy), but in general I'm very wary of anybody with dubious skating. That's not to say his skating (if indeed it is a problem) can't improve. But when I look at the teams doing well in the playoffs right now the thing I notice most is speed. Pittsburgh, Nashville, St. Louis, Edmonton, Ottawa, New York, and even Anaheim are all REALLY fast and play with incredible pace. Going forward, in today's game, I'd be really worried about taking someone who doensn't skate well. This is especially true for defensemen (which I realize Petersson is not). Look at what a game changer Nashville's defense is. They're insane. I just don't think there's any future for slower, grinding, type teams. Even if they're HUGE, I think you live and die in transition these days.
