Here is a partial list of guys making $3m and less next year that do not expire next year - so there is some incentive for the team to move them to free some money:
Atlanta: Acie Law, Maurice Evans
Boston: Rondo
Charlotte: DJ, Alexis Ajinca
Chicago: Don't know anymore who is on this team - too many trades
GSW : Wright, Randolph, Bellinelli
Houston: Landry
Indiana: Rush, Hibbert
Ckips : Thornton, Mardy Collins
Bucks: Alexander, Elson, Malik Allen
Wolves: Brewer, Bassy
NJ: Najera, Boone
NOH: Armstrong, J-Wright
Orlando: JJ Redick
PHX: Tucker, Dudley, Lopez
Sacramento: See Bulls
Toronto: Humpris
Wizards: Blatche
The ones that stand out to me are:
1. from the Bucks - Elson/Alexander - since they are in financial problems - and this could be a way to do a pick swap + player for TE + money with them
2. Wizards - if they want to do the same
3. PHX - Always good for a pick for money / being cheap
