DALLAS -- As fate would have it, the biggest offseason move for the Dallas Mavericks thus far this summer has come -- off the court.
Earlier this month the Mavs failed in their bid to acquire superstar free agent center Dwight Howard, who left the Los Angeles Lakers to sign with the Houston Rockets. But on Monday the Mavs were able to attract one of Howard's new bosses -- Gersson Rosas.
In a shrewd move which could enhance the Mavs' talent base, a source said the Mavs have hired Rosas to become their new general manager. Rosas, 35, comes to the Mavs after serving as the executive vice-president of basketball operations for the Rockets.
Rosas replaces Donnie Nelson, who was both the Mavs' president of basketball operations and their general manager. Nelson, who a source said was pushing hard for the Mavs to hire Rosas, will still serve as the Mavs' president of basketball operations.
Formerly a Rockets intern and video coordinator and part of the team's scouting department, Rosas played a key role in Houston acquiring James Harden and Howard over the past year and has been on a serious fast track. He also was the general manager of the Rio Grande Valley Vipers, which is the Rockets' NBA Development League squad.
Since Rosas became general manager of the Vipers during the 2009-'10 season, that team has captured a pair of D-League championships and advanced to the finals in another season.
Yahoo! Sports first reported the hiring of Rosas, whose immediate boss is Nelson.
