It's early, but the only game changer currently is Sarr.
He's the only one who looks like he could become a "franchise" player so far. There's some value in the draft here and there though. Holland at least defends and plays with a lot of energy. The Edwards kid at UK has tools like a more athletic Rodney Hood. The Providence kid Dual is interesting and shows a few flashes of Dejounte Murray. Whether he can really do that at full NBA speed remains to be seen. Stephon Castle becomes really interesting if he can play on-ball and make reads. I'm not as much a believer in Collier for the modern game, but I guess we'll see. To be an elite guard now, you need to be able to shoot off the dribble at a high level.
