His basketball skills are not rudimentary, he's very good at creating his shot, with adequate ball handling and a nasty crossover, has very good footwork and is crafty around the basket with a good repertoire of moves, he's a freight train of a slasher and excellent at finishing through contact, reads defenses well and is a good cutter, great in transition, has improved a lot as a shooter with the ability to shoot the 3 though his release isn't fast, is an active defender with lateral quickness and a good read of passing lanes that gets a good number of steals.
On the negative side right now he isn't a good passer, I chalk low AS/TO ratio to his tendency to finish everything by himself leading to too many turnovers, he needs to play more within the flow of the offense and to take advantage of his teammates, but that can improve in time with proper coaching which the Spurs have, kind of like Jaylen Brown did. If he measures well at the combine (over 6'6" barefoot with good wingspan) I think he's an excellent option if we don't strike gold in the lottery.
