I think Belchetz is good, but still raw tools and potential as opposed to a "now" product. Compared to a similarly sized winger with similar traits like Katolicky, I don't see the same ability to take over shifts on the regular.
There are some shifts that get your attention and showcase the potential, but just as many when you're asking him to do a lot more. I'm not really on board yet with the idea that he's some future Lemieux or at this point a real challenger to McKenna. I think it's not impossible, given his very evidently high potential, but he needs to activate beast mode for that to happen.
I felt very similar about Byfield at the same point, and he went 2OA, so he might do it, although I still think Byfield was a little better overall at that point.
