I don't get the Jabari Smith and Ace comp. Jabari Smith is/was a good spot-up shooter and switchable defensive player that can guard the rim. Ace is a an ace at shots with a hand in his face that doesn't pass and has some nice defensive tools. Being more specific, Jabari had/has no juice on the ball while Ace is all juice on the ball, they could not be more different in that regard.
Ace has a higher ceiling due to the fact that his offensive game isn't strictly reliant on having the table set for him. Smith has a higher floor because of his defensive ability.
Have to disagree with this. You may think that way of Jabari now, but in college he was absolutely a tough shot maker. Neither guy had the juice to get to the basket, but both took a heavy amount of mid range and three point jumpers. Jabari shot more 3's, but the amount of his baskets that were assisted as Ace is essentially the same.
