He had real potential, but he wasn't willing/able to go all in the way, say, a Justin Compton has... so he will never be in that league. He dove deep when he got started (and had the chemical look to go with it), but he scaled back after a few bad placings... developed other priorities (tried acting)... and lost the edge that made him a splash. Could he gain it back? Sure, time is on his side. Does he want to? Who knows...?
Here he was eight years ago.
