They other owners may have but Sterling could drag this on out of spite. He still owns the Clippers where the owners could remove the team out of the league by banishing the them. They, the NBA, can’t sell the team for Sterling.
Yeah.... there is no comparison to this case and the salary cap against Jerry Jones. This is a lifetime ban. The NBA has pulled the nuclear option as much as they feel like they can. I’d tell them to take a hike and do whatever I wanted until a court told me different.
