I think he was top 3 2010-2011. Not sure he would be that good even without concussions.
What I think he's missing from being where he was in 2010-11 is that truly dynamic skating and ice vision. He's definitely good enough in both areas to play in the NHL though.
I feel like his goal scoring is elite, maybe good enough to score 30 goals in the NHL. He has the tools to be an elite defensive center as well. People point to his height, but he's built like a brick, no problem in that sense.
Maybe its because he's now a Canes prospect, but I think I've finally figured out a good comparison. He kind of reminds of Jeff Skinner with maybe a notch less goal scoring ability, but defensive ability to stay at center and be very good defensively. I wish this wasn't the case, but the concussion history is also very similar for the two players.
