There's a lot of talk about his skating, some people say it's good and others say it's bad. To me, his top end speed is above average but his first 3 steps can definitely be improved. He gets away with it because as a center, he can get away with gliding more.
That said, because his offensive effectiveness relies heavily on the offensive cycle, which involves lots of stops and starts, he will need to reach improve his first 3 steps to be an effective offensive center at the next level. If he does, odds are he'll have lots of success in the NHL.
