Well, it's been pointed out before that he could still be adjusting to the NHL schedule and pace. He's being asked to play a lot more games now than he has in the past few season at Boston College. He's had a couple real dominant games, and a handful of pretty solid ones as well. It seems like when he isn't even on his game, he's still picking up points, though that probably has to do with the offensive role Hartley has him in. I think it'll just take him a while to fully acclimate himself in the NHL, he is still a rookie after all. He's hardly had a chance to play against any of the teams/players he's been matching up against this season, and it'll take him a while to learn how to adjust his game in different game situations.
I'm confident he'll figure it out though. That's one of the things I love about this kid, he's so smart that he consistently finds a way to get things done, and I think it's a big reason for why he's been able to step right into the NHL and be effective without having to spend time in the minors working out the kinks in his game. We've seen flashes of what he can do, and even when he's not dangerous offensively, he still pulls his own weight defensively and is far from a liability on the ice. It'll be interesting to see how he adjusts as he starts getting matched up against stronger players. Hartley has somewhat sheltered him so far. Not a lot, but a bit. He's still finding his groove in the NHL.
