Considering that a lot of NBA 7 footers have no offensive game to speak of, I'm not going to micro-analyse this kid's low post game. All I look at when I evaluate a super tall young big is if he can move well, has an athletic frame, and has decent instincts for the ball. He seems to have all that, although he's not a freak athlete like an Hakeem.
I number of years ago, I tried to help a HS prospect from Africa get to a school in the US. He was 7'2" and 280 pounds and moved well. It didn't work out do to visa issues, although I lined up full rides for the kid at two very good prep schools, sight unseen. True seven footers are in demand. According to the CDC, there are only 70 American males between 20-40 that are 7 feet or taller. An American 7 footer has a 15% or better chance of making an NBA paycheck, For someone 2-3 inches shorter, that number shrinks to an astronomically low percentage.
