He has very little ball skills and his jump shot hasn’t transitioned to the NBA level yet, at least at a consistent level. At times his feel for the game looks off. Granted he’s had some teammates that haven’t helped him and like you said limited minutes.
But he does have good athleticism. I’m guessing over time he can develop into a 15/10 guy but I dont see upside to 20 points. His offensive game has a ways to go. The real key is his defensive/rebounding ability. Hes got talent to be good but right now he’s getting bullied around a bit. I’m sure he can work on his body/strength/speed.
