Thoughts on Cason....IDK why people keep calling him small. He very clearly has plus size at the PG position, and he does very well at the things size is supposed to do. He was great at the rim, he's great at making passes in traffic, and out of all the PG's in the draft I would trust him most to guard a bigger player. So even if you think he's small on measurements (he's not), he's good at all the things size is supposed to help you with so why does it matter?
I think his playmaking is probably his most underrated trait, especially in comparison to Black. His AST/TOV was fantastic. He does have quite the number of "highlight reel" passes as Black, but he has his fair share and is also really great at protecting the ball. I have no questions about him running PnR in half court. He's super comfortable in the middle of the court and is a threat to shoot, drive, and pass. Having said that, I do think he's a guy who's going to rely on getting good screens at the NBA. He doesn't have enough natural burst or ball handling to get by defenders on his own.
Defensively I think he's the best guard in the draft. He is fantastic on and off the ball. Love how he gets around screens and plays gaps. I am not sure he will get to the Jrue/Smart level of defender at the position, but he has the potential to be that elite level defensive guard. Overall a very solid player with very few weaknesses. Not much bad to say about him, but also doesn't have the same peaks that you get from Black when you watch him play.
