for a 7 footer, very little ups/athleticism
He's 14!!
Exactly. He's probably been growing really fast, so a little awkwardness is his movements and a lack of explosiveness should be expected. I think he could def. be 14. He looks very young. He most likely is 7' too. The other players he was playing with were most likely other middle school stars and players being ranked, so theyre likely to be 6' and up.
I'm very impressed with him. He has a great handle, and post game for someone his age. Thabeet wasnt that strong of a ball handler or shooter when he was drafted, nevermind at 14. If his body stops growing and doesnt cause him too many medical issues, he could be a beast.
