Mark Cuban expounded upon his new partnership with the Adelson and Dumont families after the NBA approved the sale of his majority stake in the Dallas Mavericks.

"Nothing's really changed except my bank account," Cuban said on Wednesday. "I feel really good. I think it's a great partnership. It's what the team needed on the court and off. I'll still be overseeing the basketball side of it, but having a partner like Patrick and Sivan and Miriam and their ability to build and to redevelop the arena and whatever comes next beyond that just puts us in a much better position to compete. That's all. That's what it comes down to."

Cuban will maintain a 27 percent stake of the Mavericks' ownership and serve as the team's alternate governor. He acknowledged that there is "no contractual language" in the purchase agreement regarding his authority over basketball operations and that ultimately Patrick Dumont would have "final say" as the team's governor.

Cuban does not expect Patrick Dumont to be heavily involved in basketball personnel decisions.

"He basically said, 'Just do what you got to do. I want to win,'" Cuban said. "I mean, financially, we're in a far better position this afternoon than we were yesterday afternoon to be able to compete like that. So what did [Houston Rockets owner] Tilman [Fertitta] say about being a middle-class billionaire? Those are facts in this day and age. It really matters. So having the partnership and having eventually new and deeper revenue sources allows us to compete better. I talked to Patrick a lot and Miriam and Sivan, and they're committed to winning."
