I totally agree. I think Ayton is in the top 3 prospects and has a chance to be a star. My point is a limited one, namely that Ayton's physical development relative to his peers is a reason to discount some of his numbers, and that conversely Doncic's body relative to his peers makes his production more impressive.But the body matters. Ayton isn't exactly Shaq but you can't dismiss size.
None of that contradicts the fact that his body and athleticism make Ayton an amazing prospect. Simply that he's going to rely more on skill in the NBA because theres lots of big boys up there. And that is not to say he isn't skilled either!
Edit: To elaborate, I have watched a few highlight packages of Ayton against some small teams where he puts up 30 points or something, and in some of them a good half of his points are off simple lobs where he has five inches on his defender. Again, that size and athleticism won't disappear in the NBA. But it doesn't translate as well as, say, a smooth shooting stroke does.
