He has NBA body but not skills yet, but he certainly will. Physically, he's the same height as lebron, probably close to the same vertical leap. He's 30 pounds lighter than lebron was at this age, so I don't know that he'll be dominant at that level... although once he gets to college and starts eating, then to the NBA and enjoys some GH, he'll probably be unstoppable.
I'd say he's probably more the next Durant, rather than the next lebron.
