There were those here who were willing to get rid of Deng, Hinrich and even Noah if it meant getting a marquis player. i wasn't one of them. I was willing to trade either Hinrch or Deng for the right player (but not both), so I'm very happy with the way things worked out.
I admit the complaints regarding Deng were justified given his large contract, the number of games he missed and his inconsistent production (i.e., disappearing in big games). The fact that the Bulls tried to trade him and couldn't shows that most other teams felt the same way, but he was still the Bulls leading scorer last year. I thought losing him and Hinrich would be giving up too much for the Bulls to overcome.
He has changed his game this year in a way that really benefits the team, improving his 3 point shot, deferring to Rose and playing off the ball more. A lot of the credit should go to Thibedeau for finding the best way to get the most out of him. The Bulls have the second best record in the NBA right now, and I don't believe that would be the case without Deng.
