I think it’s more a general underrating. Reality is stacking him up against the draft crop you just can’t say as it stands he isn’t number number one. But some seem to think he has maxed out and won’t improve much. Whereas he’s not that deep into his career and there’s no reason he can’t improve.Not sure he is under rated. Most are calling him a gun and to date the clear number 1.
What the debate is if he will be the number 1 at careers end.
