I liked what I saw from him-
He's hungry to succeed (which is more then I can say for the majority of the team), he was elite on faceoffs tonight, he showed he has some vision out there and he clicked well with JVR and Kessel
When Bozak and Kadri get back where he fits is up to him, if he plays like he did tonight then he makes a strong case to stay on the top line, if he falters (and he could) then I think he slides down to the 3rd line. The better question is what happens when Bozak/Kadri/Bolland are healthy and back in the lineup then what happens to him? I can't see him going to minors, espically after giving up a prospect and 2 picks, he's here to stay I think, I heard somewhere he can also play wing I think that he'll switch over once all 3 of our centres are back and healthy.
The one downside is he doesn't appear to be a physical or defensive oriented player though.
