The addition of Ethan Casson as the Mavs’ new president will allow Welts to focus on the franchise’s bigger picture within its home city.

The Dallas Mavericks have hired Ethan Casson in a new role as president, giving CEO Rick Welts someone to handle daily operations on the business side while he focuses on the franchise's plans for a new arena.

Casson is the Mavericks’ second major hire on the business side since Miriam Adelson purchased a majority stake in the team from Mark Cuban in December 2023. Seven months ago, the Mavericks brought on Rick Welts as CEO. Casson will directly report to Welts.
