Now that the Mavs have their backup center, signing 6-11 Jamaal Magloire Tuesday, they still have one open roster spot and their mid-level exception to spend.
The two big names out there are Brent Barry and Sam Cassell. Barry was waived Friday by the Sonics after being traded there by the Spurs. If Barry is going to re-sign with the Spurs, as most initially expected, he's doing one heck of a sales job to make it at least look like this whole thing wasn't a wink-wink deal between the Spurs and young Sonics GM Sam Presti, the former Spurs assistant GM. Barry has the Suns and Rockets waiting and to some extent the Mavs. He's expected to make a decision at some point today.
As for Cassell, who is expected to be bought out by the Clippers by Wednesday so he can join another team and be eligible for the playoffs, has given every indication that he wants to join good buddy Kevin Garnett in Boston. He'd make a nice fit for the Mavs, who are currently going with 6-8 Devean George as a point forward to back up Jason Kidd. J.J. Barea is their only other choice as long as coach Avery Johnson wants to play Jason Terry exclusively at shooting guard.
