I think that's a little pessimistic, but you could be right. I agree that we shouldn't ignore his weaknesses, he's got a lot to work on but with the raw skill that's already there, if he can work his tail off over the next 2 years, and then work with Berube (hoping he sticks around for awhile), he's going to be something special. The stuff he does to get the puck to the middle of the ice... you can't teach that. I think his shot is pretty good, it could certainly use some work but it's not as bad as you're making it out to be I don't think.
His highlight reel is very impressive, and it shows that his main weakness is along the boards. He's sneaky elusive in front of the net and on the cycle, which is huge. A lot of the stuff he does here he won't be able to pull off in the NHL, but of course he's going to have to evolve to be a 1C anyways, that's the expectation here. One more disclaimer, this is obviously a highlight reel, so it doesn't show his mistakes and flubs. Watch for #25:
