I actually saw him (Hook) play in a Summer ProAm League game at Kezar a loooooooooooong ass time ago. I left the game after (in a half court set mind you), he shook his check at the top of the circle then proceeded to take off from the dotted line and dunk on 3 dudes.
Considering Lebron is 6'9 275, the shit he does is just as impressive as Hook. Carrying that weight against gravity can't be easy.
