UPDATE: The big fella seemed to confirm the rumors this afternoon, tweeting his excitement to be moving on to Dallas and saying goodbye to San Antonio: “SA you always in my heart! … Dallas!!!!! Now lets have some fun!!!!”

According to ESPN, the Mavericks and free agent big man DeJuan Blair are inching ever closer to a deal: Sources said that the Mavericks — who remain one of six finalists for the services of Greg Oden — are in advanced talks to add Blair to a revamped rotation of front-court sidekicks for Dirk Nowitzki. With one source saying Tuesday that a deal looks ‘promising,’ the former Spurs center appears poised to join new projected starting center Samuel Dalembert and the re-signed duo of Brandan Wright and Bernard James in a posse of centers to play alongside Nowitzki after Dallas lost out to Houston in the Dwight Howard sweepstakes. Although the Mavericks are essentially restricted to offering minimum contracts at this point in the summer after making a number of signings post-Howard, they continue to hold out hope that Oden will decide that Dallas is the ideal place to launch his comeback under the watch of longtime Team USA trainer Casey Smith and team doctor Tarek Souryal.”
