He's the worst skater on the roster along with Goodrow. That's not good company to be in. He has little-to-no motor either.
His stride doesn't look terrible to my eye, but he has no explosiveness and a below-average top-end speed. Agility and "bend" look ok. He needed to be focusing on this years ago, but now it's just frustrating to watch him try to move around the ice.
I'm rooting for the kid. I really am. But he needs to work on his lower-body explosiveness in a big way. I do like that he's gotten a bit nastier with his physical play, though. Instead of just letting defenders mercilessly beat up on him and just absorbing it, it looks like he's fighting back quite a bit to my eye.
