he has a 7'1 wingspan. Depending on how tall you think he is he would either be tied for first or second in the difference between wingspan and height in the 2019 NBA Draft.

Talen Horton-Tucker measured in at 6'4 with a 7'1 wingspan. If Bamisile is 6'5 with a 7'1 wingspan he would be 2nd...if he is 6'4 then he is tied for first.

A 7'1 wingspan makes JB play as though he is really about 6'8/6'9, but still has the quickness of someone who is 6'4/6'5. You'll see a lot of videos of how athletic JB is, but really, he only needs to be as athletic as someone who is 6'8 to finish the same type of dunks.

Defensively this is a huge plus for him, which is why it is easier to project him as a good player before Game 1 than say someone like NAW who was 6'5 with a 6'9 wingspan (no slouch there either)...NAW needed to buy in defensively more than JB does. Just as Klay Thompson needs to buy in more defensively than Giannis Antetokounmpo.

Anyway, if youre wondering why I am less careful about someone like JB than others who have yet to play a game...this is why
