The exodus from the Rockets' front office continued on Monday when the Dallas Mavericks reached an agreement with executive Gersson Rosas to serve as general manager, league sources confirmed to CBSSports.com.
Donnie Nelson remains in place as president and Tony Ronzone remains director of player personnel, sources said. Owner Mark Cuban, intrigued by the work Rosas did as a key member of Houston's front office in recent years, was sold on adding the 35-year-old in a shakeup of his front office.
The Rockets have missed the playoffs in three of the past four seasons. But GM Daryl Morey's front office has scored big in the past nine months by parlaying draft picks and assets into James Harden (via trade with Oklahoma City) and Dwight Howard (via free-agent signing from the Lakers). The Mavs have fallen short in their free-agent pursuits since breaking up their 2011 championship team.
Rosas joins fellow former Houston exec Sam Hinkie in departing the Rockets' front office in recent months. Hinkie was hired as GM of the Philadelphia 76ers in May. Also, Arturas Karnisovas left the Rockets this summer to become assistant GM in Denver under new GM Tim Connelly.
With Rosas' hiring in Dallas, the Mavs become the ninth NBA team with a new GM or president this offseason (counting Doc Rivers, who will serve as both coach and president of the Clippers).
