This may not be as in depth as you’re hoping for, but I pulled this together a few weeks ago. Here’s the link to the post and I’ll recopy the image below.
And basically my take away from it was that if you’re a guard who is going to be good at UVA, you will earn at least some meaningful playing time your first year. The only real exception was Devon Hall. Now of course circumstance and roster composition affect this and the sample size isn’t huge, but the Bennett era is not filled with guards who were quiet their first years and then went on to great things. Kind of seems like you either got it, or you don’t, and we can see it pretty quickly. Bigs are obviously more complicated.
