I haven't heard where Duhon is likely to end up but the consensus seems to be he won't be back in Chicago.
As for Brand or Boozer to the Bulls, this is the first I've heard mention of Boozer being interested in Chicago. While Chicago is larger market than Utah but I wouldn't think that he would risk going from a rock solid franchise where he is the star and surrounded but good talent to go to the Bulls which are in complete disarray and likely to completely redo their roster this year. Brand might have some interest (although the rumors are that he want to go to Miami). He wouldn't risk as much as Boozer since the Clippers already suck plus haven't lived in Chicago already, he may prefer the familiarity.
I'm betting that Deng stays in Chicago. After all of the refusing to trade him hoopla last year, I don't see management letting him get away now. Too much crow to eat if you ask me. Gordon is another story. They obviously are going to try to make Rose the focus of the future and with so many other guards, someone has to go. Hinrich has a bing contract and has been mentioned in a lot of trade rumors but Gordon might have more trade value. I think that they need to trade both and try to get a veteran backup (Duhon might actually fit the bill and wouldn't cost to much) to show Rose the ropes and bigger 2 guard that can play better defense than Gordon but is also a decent scorer.
Anyway, my two cents worth.
