I definitely didn't mean my question as a slight to his goal-scoring ability as he's one of the elite goal scorers in the game, nor his talent to adjust to being more of a play-maker. It's just incredibly rare for a centre to be the primary goal scorer on his line/team consistently for more than a couple seasons. There's really not that many centres since Phil Esposito that were 'that guy'. Wayne and Mario could do it all but when you think of goal-scorers - it's predominantly wingers and guys like Lafleur, Bossy, Kurri, Gartner, Neely, Brett Hull, Selanne, Ovechkin, etc.
It's just the different demands of the position as despite his talent, I don't think I'd gamble on him challenging for The Rocket many times. I think he has a decent chance of winning one or two of them over the next couple seasons but I think as he matures and becomes a bit more dominant of a player that you'll conversely see the goal-scoring dip.
