I am just starting to dive into the draft prospects and the two players Anthony Black's game reminded me of were Kyle Anderson and Joe Ingles in that he is a connector on offense and a good defender with active hands. But I think he will be an upgraded version of those players (better athlete, better passer, better foul drawing, etc.). Although he will not be the shooter Ingles has become, I expect he will be better than Slow Mo and overall a reasonable threat.
I think Black's drive game will be similar to Ingles/Anderson in that it is based on straight line drives and change of pace (with very little wiggle) and he will do it with a pass-first mentality on the drive. That being said, he is a much more physical driver than either of those two comps and I think he will draw a lot of fouls on drives. Honestly, I think he has Jimmy Butler foul drawing potential (which is probably overly optimistic).
My favorite part of Black's game is his ability to pass for layups/dunks. He showed this from the midrange, from outside the arch, from under the basket, in transition, literally everywhere on the court. I think this is a much harder skill to learn than just passing from the paint to 3 pt shooters (he also showed that ability). That skill would be really valuable for this version of the Jazz because the current core players (Lauri, Kessler, maybe Oachi) are all play finishers but not creators. So having a floor general that can make passes puts them on another level.
Overall, Black is my favorite guard prospect for the Jazz in the 7-10 range. IMO he has all star potential (think prime Kyle Lowry) and he is very likely at least a good starter (think Fultz this year).
