Mark Cuban On NBA 'Owner' Term, 'It's Not That Big a Deal'

Mark Cuban ain't losing sleep over the controversy in the NBA over the term "owner" -- telling TMZ Sports, "It's not that big a deal."

"If you run a company, own a company, start a company ... you decide [on what to call yourself]," Cuban told us.

Of course, Cuban purchased the Dallas Mavericks back in 2000 and is still listed as "owner" in the team's 2018-19 media guide.

The issue ... several players, including Draymond Green, have voiced concern over the term -- essentially saying it's racially insensitive in a league comprised of mostly black players.

Several teams have moved away from the term -- including the Philadelphia 76ers and the L.A. Clippers -- and even NBA Commish Adam Silver has said he's sensitive to the issue.

In fact, Silver told TMZ Sports the league office is no longer using the term "owner" -- opting for the term "governor" instead. Though Silver made it clear there is no hard rule banning the term in the NBA.
