As a Canes fan, I can say I haven't been impressed. Although I thought he played the best he has all tournament the 2nd half of the game against Sweden (the 1st half, I thought he was brutal). After that one play where he crept in and got a nice shot of, he seemed to gain confidence. Later in the game, he also had a nice hip check against the board, won a couple of puck battles (which he hasn't done all tournament), didn't make any glaring mistakes and skated with a little more confidence.
All that said, on the whole, he's looked pretty suspect to me. Weak on the puck I can kinda understand as he's a lightweight and needs to bulk up, but he's been indecisive and timid, even when he wasn't under pressure. You can see skill, but he's a LONG way from being an NHL player. That's ok though, because with Slavin (22), Hanifin (19), and Fleury (20), the Canes won't need to rush him and "hopefully" he can put on some weight and develop.
