Breh a lot of cats in the nba are athletic as fukk but it doesn't translate into productive nba play. Heck Thomas Robinson is athletic, practically a freak of nature, but his nba career is garbage for being such a high pick.
Robinson is a bit undersized, he's athletic because he has to make up for lack of height/length and skillset. They list him at 6'10, he's really 6'8 in shoes which is right around the height of your average small forward.
