The Atlanta Hawks, who have a trade exception that would allow them to absorb Korver's salary without sending anyone back, are reportedly at the top of that list:
Korver talks with Wolves and Blazers have died. Assume Bulls will circle back to Atlanta, which has traded player exception he'd fit into.— K.C Johnson (@KCJHoop) July 12, 2012
If Atlanta doesn't have to give up any significant assets, picking up Korver would make a lot of sense, as he would allow them to remain competitive without sacrificing any of their cap flexibility going forward. He'll be paid $5 million in the last year of his contract this season.
