I'm as high on this kid as anyone, but people need to understand that the comparisons being dropped here are mostly in regards to playing style. From a pure style standpoint, I mentioned at beginning of the last thread Gretzky's name. In no way do I think JG is gonna put up 150+ pt seasons, nor do I think he's the next Crosby. I think MacKinnon is the best current young player/prospect in the game, Gaudreau may be around 5-7. I do believe that he's capable of being a PPG player if everything goes right for him, and if it does, Kane may be the best example in today's game from a style/production standpoint.
I do not feel he has much of a bust factor in the NHL in the sense that he he won't become a regular. I think it's entirely possible that he develops into 50-60pt player, but I personally feel that once he figures out the NHL game, he will become a dominant player.
Either way, this is fun discussion. He's the kind of player you get excited about (hence his 3rd thread). Can't wait to see him play next season.
