Like it or not, Joakim Noah is expendable.
Most of those teams that have won a championship have had an All-Star low-post scorer; Noah really isn't a guy who is going to get the ball thrown into him enough time to make plays.
So, in a nutshell, Carmelo Anthony would be tons more valuable to the Bulls (if they can unload Deng's hefty contract) than Noah.
I love Deng and Noah, but Anthony is too dominant of a scorer, and is now becoming one of the NBA's better defending wing guys, as well. Plus, he has the size and high-post ability to play the 4 against small line-ups.
I would eloborate on this more, right now, but I need to run to class...
