My thought is that he's great against lower opposition in the VFL. Great against people that are undersized or not as strong as him. But in the big dance he's up against the best of the best every step of the way. And he can't out-body people most of the time and can't lead with clear space. He's an inbetweener. Not AFL standard for the most part, but way too good for VFL level.
It's just a reality he's not going to be as good as what some people will lead you to believe
