He is clearly confused, he himself called his season embarrassing twice over the past regular season and he was on the verge of tears after game 2. He's referred to many other players in comparison to himself. He has not yet been able to play a consistent way, and much less to do so consistently.
His production is a function of how he plays -- if he's actually going to be a trenches, N-S, powerful forward type then expectations are different than if he plays as a Euro-style playmaker.
I'm glad you're satisfied with 50 point seasons that embarass the player himself, and I won't try to change your mind. I think he can be a very effective 50-60pt player or a very effective 70+pt player but he's not there yet. Or maybe he is.
