6:30pm: The Mavs sent out a press release confirming that Rosas would no longer be with the organization, and it includes a statement from Rosas, who says the decision was entirely his.
“I made the personal decision to resign as general manager of the Dallas Mavericks after determining that the position was not the best fit for me at this point in my career,” Rosas said. “The decision was made solely by me, as I firmly believe this change is in my best interest.
Rosas added that Cuban asked him to reconsider the decision, but he ultimately turned the owner down. Rosas said he and Cuban “part as friends.”
1:56pm: General manager Gersson Rosas‘ stint in Dallas has come to a premature end, according to Marc Stein of ESPN.com, who reports (via Twitter) that the two sides have parted ways. The Mavericks only hired him away from the Rockets about three months ago, but Stein tweets that questions about Rosas’ fit in Dallas were raised almost immediately upon his arrival.
Rosas spent the last nine years with the Rockets, steadily rising through the organization during that stretch. He has also served as the GM for Houston’s D-League affiliate, the Rio Grande Valley Vipers, helping to lead the squad to a pair of D-League titles in recent years. He was reportedly coveted by the Nuggets and Spurs before he agreed to join the Mavs’ front office.
While Rosas’ departure will alter the structure of the Mavs’ front office, it shouldn’t have a significant impact on the team’s basketball decisions, since owner Mark Cuban and president Donnie Nelson continue to have the final say.
