Mavericks landed Santi Aldama in a six-team deal this week, which is one way to describe adding a stretch four to a roster still trying to remember what it looked like before it traded Luka Doncic. The more interesting filing showed up in a Dallas courtroom, not a box score: Mark Cuban is now suing the Mavericks' current ownership group over the Miriam Adelson-Dumont family's handling of the arena situation and, by extension, the Doncic trade fallout, the same deal that turned a Western Conference contender into a case study in how fast equity can walk out the door once you sell control. Cuban built that franchise for two decades and still can't stop it from becoming a headline for the wrong reasons.

Which is the real story here. Cuban sold the Mavericks to Adelson and the Dumont family in a deal that closed at a $3.5 billion valuation, kept a minority stake, and then watched the new majority owners ship out the best player in franchise history for Anthony Davis and a package that now, one year and several roster patches later, includes Aldama as a depth move to cover the hole. A lawsuit from the guy who used to run the place isn't nostalgia. It's what happens when the seller believes the buyer is mismanaging the asset he still partially owns, and it turns the arena financing fight and the trade into the same argument: who actually runs the Dallas Mavericks now, and whether anyone bothered to ask Cuban first.
