Ex-GM Rosas: Mavs 'Not The Best Fit For Me'

The Mavericks parted ways Tuesday with GM Gersson Rosas, a conflict regarding organizational roles possibly at the core of the quickie divorce. President Donnie Nelson confirmed the change, saying only, 'We wish him nothing but the best in the future.' Mark Cuban expressed 'disappointment.' And Rosas? He frankly cited 'fit' as the reason.

The Dallas Mavericks parted ways Tuesday with GM Gersson Rosas, and DallasBasketball.com has been told a conflict regarding organizational roles is at the core of the quickie divorce.

"We wish him nothing but the best in the future,'' team president Donnie Nelson told WFAA-TV, confirming the change.

At the same time, Rosas released a statement through Mavs PR:

"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," said Rosas. "The decision was made solely by me, as I firmly believe this change is in my best interest.

"Mark Cuban asked me to reconsider my decision, but graciously accepted my decision and we part as friends,'' Rosas continued. "I would like to thank Mark and the Dallas Mavericks for the opportunity."

Cuban, in the same release: "I was disappointed when Gersson told me of his decision, but I understand and all of us wish him the best.''

Nelson, working under Cuban, was pivotal in pinpointing Rosas, 35, as the man to serve beneath him on the organizational chart as the general manager.

The short version of Cuban's stated view of the hire in July? "Brainpower, organizational management and process power." Rosas has those qualities. He spent a decade with the Rockets, starting as a video coordinator and being promoted to VP of basketball operations in 2012.

Rosas' short run in charge -- but not as "in charge'' as he seemingly wished to be -- leaves the Mavs with a void as they prepare for Wednesday's season-opener at the AAC against visiting Atlanta. The "Triangle of Trust'' (Cuban, Nelson and coach Rick Carlisle) will move forward without the help of a staffer viewed as so key just three months ago.

What is the story behind the story? How did Rosas rub one corner of the "Triangle of Trust'' wrong? How could Rosas somehow find conflict in the well-defined organizational chart?
