11:19am: If the Mavs and Blair agree to terms, it will likely be for a one-year, minimum-salary contract, according to Alex Kennedy of HoopsWorld. While there was some talk of a sign-and-trade, Blair figures to sign for a year and test the market again next summer, says Kennedy, adding that the ex-Spur figures to choose Dallas' offer over similar proposals because he'll get a chance to play major minutes with the Mavs (all Twitter links).
9:58am: The Mavericks are engaged in serious talks on a deal for DeJuan Blair, reports Marc Stein of ESPN.com (via Twitter). According to Stein, the odds of the two sides reaching an agreement are "promising."
It'd be a little surprising if the Mavs were able to land Blair, since the team appears to be capped-out, and Blair's asking price was said earlier this month to be in the $3MM range. The big man was also reportedly seeking a multiyear commitment. Based on reported contracts and salaries to date, it seems as if the Mavs have used their cap space and signed Wayne Ellington using the $2.65MM room exception. Assuming that's the case, Dallas could only offer Blair the minimum, unless a sign-and-trade deal can be worked out with the Spurs.
Blair, 24, has spent all four seasons of his NBA career with the Spurs, but saw his role reduced as Tiago Splitter emerged as a productive starter for the team. After averaging 8.5 PPG, 6.4 RPG, and a 17.5 PER in his first three years, Blair's rates fell to 5.4 PPG, 3.8 RPG, and a 14.6 PER in 2012/13.
