He has been in a lot of trade rumors almost the whole season and now the offseason too, maybe the Bulls let him know that they are going to trade him at whatever cost since they already have Derrick Rose, a possibilty is too the Knicks for David Lee.

That trade would help both teams since the Bulls are going after Lee right now and they appear to be the front runners for him, for the Knicks they get a good young Point Guard in which they need because Duhon isn’t good enough to be the Starter.

Hope i Helped.
