Mavericks and General Manager Gersson Rosas Part Ways
(DALLAS) -- Less then three months on the job, Gersson Rosas is no longer the general manager of the Dallas Mavericks.
The two sides parted ways on Tuesday, just one day before the team's season opener against the Atlanta Hawks.
"I made the personal change decision to resign as general manager of the Dallas Mavericks after determining that the position was not the best fit for me during this time in my career," Rosas said in a statement to ESPN.com.
"Mark Cuban asked me to reconsider my decision, but graciously accepted my decision and we part as friends. I would like to thank Mark and the Dallas Mavericks for the opportunity," he added.
According to ESPN.com, Rosas wanted more control over Dallas' basketball operations. Rosas was working under the president of basketball operations Donnie Nelson, and Rosas was uncomfortable with the power structure. There had been growing concern of how Rosas would fit in with Dallas' front office.
Before coming to Dallas, the 35-year-old Rosas previously worked with the Houston Rockets front office.
