Mavs move on after GM's trial period

DALLAS -- Mark Cuban described Gersson Rosas’ brief tenure as the Mavericks’ general manager as sort of a trial period.

Rosas, who was hired out of Houston’s front office this summer, lasted three months before resigning on the eve of the season.

“He kind of had the opportunity to stay 90 days, see what happened,” Cuban said. “He made his choice. I wish him the best. He’s a good guy. I liked him. We move on. ...

“Not really much to go into. It just didn’t work out. Smart guy, good guy, wish him the best. Just didn’t work.”

It was really more of a mutual decision. Rosas said in a statement released by the Mavs that it wasn’t the “best fit,” and that seemed to be a consensus opinion in Dallas’ front office.

Cuban made it clear when he hired Rosas that the general manager would report to longtime president of basketball operations Donnie Nelson. Rosas unsuccessfully pushed for a larger role in the Mavs’ decision-making process.

So why hire a GM if he isn’t going to be given the freedom to generally manage the team?

“I’m not big on titles,” Cuban said. “That was the title he wanted. I pretty much let people pick their title. Notice we didn’t have a general manager before. That was it.”

The Mavs apparently won’t have a general manager again any time soon. Cuban says he has no intention to search for a replacement for Rosas.

Status quo in the front office suits coach Rick Carlisle fine.

"The best I've ever been with," Carlisle said of the Mavs’ front office. "We were strong to start with and we're still strong, so that's where we are."
