Billionaire investor Mark Cuban, owner of the Dallas Mavericks basketball team, asked which move he kicks himself over in his almost 23 years of NBA ownership.

“Probably letting Steve Nash go. Yeah, I regret that. It’s been almost 20 years now, and I still regret it,” Cuban said.

Nash played six seasons in Dallas but when his contract expired he left the Mavs for the Phoenix Suns.
