You don't have to buy it but that doesn't change the fact that he is doing exactly that.
Either way, he is going to be a Hab so you may as well jump on board. I have watched him for a very long time, starting with his GTHL days with Don Mills. The kid has always been a winner, I am not worried about him. He is just perhaps a little to eager to prove that he is defensively responsible and is too eager to accept the F3. He will adjust as the IQ is so bloody obvious with his lane recognition, multi-layered passing strategies and understanding of how to shape the geometry of a play without having the puck. Combine this with the fact that he has the size, skating and puck skills to take advantage of his mind processing the game faster than anyone on the ice. He looks like a defensively responsible center version of Huberdeau with a better shot. It may not happen right away but he will eventually be a top 10 center in the NHL and maybe even more imo.
