Shumpert is a tweener who's efficiency has gone from bad to worse in the three season in the NBA. BUT he's still just 23 and he's still on his rookie deal (due $2.6 million next year, the last year of his contract).
Would you give up pick 36 for Shumpert? I wouldn't.
Thinking out loud here...how about the Bulls get Shumpert and the Rockets pick 25. Rockets get Ersan. Knicks get pick 36. Bucks get pick 19.
Bulls: send pick 19, receive Shumpert, pick 25
Rockets: send pick 25, receive Ersan
Knicks: send Shumpert, receive pick 36
Bucks: send pick 36, Ersan, receive pick 19
