Full disclosure never seen him play but from hearing what people have to say about his game and depending on how tall he really is or turns out to be (hehe) it sounds like best case scenario is he could be really really good as a new age four man.
Stretch the floor, attack the rim, contribute on the boards, but probably struggles guarding athletic two guards and wing players. Sounds like where ever he ends up he will not be a plus defender to getting an extra inch or two could really help him in that department.
I'm really hoping his dad is right about possibly growing to 6'8 or 6'9.
