Cuban supported Trump before he was against him. Did you conveniently forget that he even let him use the AAC in Dallas to host one of his rallies? Feel free to speculate about which billionaire is worth more, but I'm going with Forbes' data that says Trump is worth more (not that I really care tbh). This is all about self-promtion for Mark Cuban, anyway.
The Mavericks have a championship ring because of Dirk Nowitzki, and should have competed for more than one, but they have Cuban to thank for that. He's actually become quite the laughing stock in the NBA because no one wants to play for Dallas, even though he always compensates his players well.
Are you really that stupid? Cuban doesn't own the American Airlines Center...he doesn't have the ability to give anyone permission to use it.
The city of Dallas owns the arena and makes those decisions.
Dirk and the Mavericks DID compete for more than one ring you dolt.
2006 they played the Heat in the Finals.
Even before Dirk the team was constantly in the playoffs with names like Tarpley...Aguirre...Blackman...Perkins and Harper.
Please stop trying to talk about Texas sports teams when you clearly know nothing about them. It will save you lots of embarrassing moments.
