Spurs have two superstars right now. Duncan and Leonard. Duncan has declined a little this year, but he's still one of the top 5 defensive players in the league and above average offensively. It's actually mind-boggling how good Duncan is at 38.

As for what happened to the Bulls, they regressed to becoming a good but not great team. One superstar...no matter where they play, is pretty much what that gets you. Jazz need another. Could be Exum if he can figure out how to become at least competent offensively, because he is already very good defensively.
