Bradley has absolutely zero offensive awareness. I would liken him to Gerald Green in that regard.
I don't know if this ability can really be "learned". It seems like more of a natural thing. He plays very fast with no pace and no confidence.
As a small guard, you can't be a purely defensive player in this league, not as a rotation player.
IMO, he is on pace to be in the D-League. I hope I am wrong.
