Kids athleticism is not great, nor is his conditioning. Weight gain could be a big future problem as his dad was a huge NFL lineman. He also has a game that is more Jahlil Okafor than the stretch bigs team covet this year, though his set shot three point form is good. In a different year, he probably isn't a lottery pick.
But there is potential there. He needs to dedicate time to getting and keeping himself in NBA shape and needs to get to be at least a 35% three point shooter to really maximize his potential as, for his size, he is neither a great rim protector nor rebounder. Good rebounder. Below average rim protector.
