Unrestricted free agent James Posey has drawn the interest of several teams, including the Mavericks.
But Posey, the one-time Miami Heat defensive stopper, is caught in the same logjam as many other unrestricted free agents who are waiting for restricted free agents Pietrus and Sasha Pavlovic to be signed.
Teams have been reluctant to commit to other big guards or small forwards until Pietrus and Pavlovic sign.
Posey's agent, Mark Bartelstein, sees some progress.
"We're talking," he said. "There have been a number of conversations."
Bartelstein said another client, P.J. Brown, plans to talk with several possible contenders before making a decision on whether to play a 15th NBA season or retire.
At 6-11, Brown could potentially give the Mavericks another big body to go with Erick Dampier and DeSagana Diop.
