I think the part of the Okafor story people tend to miss, is that he's actually a terrible OFFENSIVE player. He's more Anthony Bennett than just a guy with defensive problems.

He's one of the worst players in the league, who somehow manages to be one of the worst +/- guys as well, while playing for the Sixers.
Does he have talent? Yes, just like Anthony Bennett and Sully have talent.
