Zhaire Smith is a for-real prospect. He has a good feel for the game and Westbrook-esque athleticism. I'm not surprised at all that he is rising. I would not be surprised if he is the first guard taken (after Doncic). I'd take him before Sexton, SGA, or Young.
The problem is that he is probably not a primary ball-handler at the next level. In the modern NBA, if he doesn't have that skill, that makes him a high-upside 3-D prospect.
My comparison has been an Oladipo-lite or a Lee-strong. If he can develop his handles and shot creation, he has a chance to be an All-star. Otherwise, he will be a very high level two-way rotation player.
