I am grading some of these guys on game tape and stats and some just on stats, so my list definitely isn't perfect, but grading the top 20 picks from 1-5 stars, I see 2 potential 5-star guys (Mudiay, Towns), 3 potential 4-star guys (Okafor, Stanley, D'Angelo Russell), & at least 5 potential 3-star guys (Harrell, Looney, Winslow, WCS, Dakari) with potentially more for sure.

I'm higher than average on Towns, Stanley, Russell, WCS, R. Hollis Jefferson & Trey Lyles.
I'm lower than average on Okafor, Harrell, Myles Turner, Justise Winslow, Caris LeVert, Cliff Alexander, and Sam Dekker. Think they're all overrated or inferior to a similar prospect in a similar draft range. But I need to see more and am loving the posting of upcoming games.
