"By trading center Aaron Gray to New Orleans for veteran guard Devin Brown on Monday, the Bulls are clearly hoping to move John Salmons or Kirk Hinrich before the Feb. 18 trade deadline.

The idea is to trade one of those guards for an expiring contract and create even more cap room to pursue free agents this summer. Such a deal won't be easy, because few teams are willing to take on add salary to their payrolls right now, two sources confirmed.

The 7-foot Gray has barely played this season after recovering from a stress fracture in his leg. A second-round draft pick in 2007, he did have some strong moments in his first season and a half with the Bulls."
