Mark Cuban accuses Mavericks owners of freezing him out in proposed arena move, newspaper reports

Mark Cuban accuses Dallas Mavericks governor Patrick Dumont of excluding him from business opportunities related to a proposed arena move. Cuban claims Dumont, along with Miriam Adelson's family, has engaged in adversarial practices since Cuban sold his majority stake in 2023. The filing reveals Cuban was unaware of a trade involving Luka Doncic to the Los Angeles Lakers until it was finalized, leading to the firing of former general manager Nico Harrison.
