Just from the little I've seen of him, so its not an opinion I feel incredibly strong about, but the doubts about his mental speed are still there.
Watching some of the WJC and his WHL clips I think he looks at his best carrying the puck, using his size and strength to beat defenders but that he doesnt always know where to go with it or make the right decision fast enough. For me at least, the WJC games kind of highlight this because of the relative skill level in the game. I just remember thinking there were a number of plays that died on his stick compared to his teammates.
So I kind of stand by my draft opinion that I dont think he'll bust or anything but not sure if he'll be a great 2C.
Lethbridge Hurricanes Lethbridge is posting game videos so I'll have to watch more and see if I feel differently.
