Cuban has sold the Mavs to Adelson-Dumont Family

[F Gump]

Didn’t Perot retain some of his stake in the Mavs? The AAC and the surrounding area are his baby too. If Cuban could have buried the hatchet with him he wouldn’t have had to sell the team.

The fact that there is a new arena looming makes sense of all of this.

Perot's was an old real estate venture one that Cuban didn't do, didn't know how to do, didn't want to do, didn't see the money he left on the table.

This is a NEW real estate venture. Perot could never be Cuban's partner in this new venture -- his pockets aren't deep enough. Not only that, but this new venture will likely siphon big value away from Perot's old venture, as the new Unnamed Arena will be the cornerstone, that will create huge value for surrounding real estate, and the Obsoleted AAC will no longer be the place to be (with real estate values following accordingly).

As for Cuban having to sell, it's more of an investment than a sell -- he is swapping part of a smaller valued item for a sizable share of what he expects to be a massively bigger one. It's the Disney World model, and for years has been adopted by other sports owners WHEN they build a new stadium/arena. Cuban has the team who is about to "need" a new playground, and he's partnering with someone who can help him leverage that opportunity. They will grab a huge valuable footprint of land, based on that (supposed) need, and also get support from city, county, and state to allay their costs.
