I don't really watch him enough, but I've seen him a few times in junior and in the WJC... my general feeling is that he has the skills required, and so you can't count out guys who have that skillset when they are still young, but... I'm not sure if he has the mindset? He seems to play more of an individual one-way game at a glance... and once he loses that additional fraction of time and space, not sure he can find a way to fight through?
It is just a quick impression from very limited viewing, though. As a Habs fan, I'd be thrilled if people who watched him more could come here and say that, yes, he has a good chance to make the NHL!
