Donald Sterling, longtime owner of the Los Angeles Clippers, was barred for life from the league and fined $2.5 million by N.B.A Commissioner Adam Silver on Tuesday for racist comments captured on an audio tape that Silver said Sterling admitted were his. Silver said Sterling would be barred from any contact with his team or the league and he will urge the leagues board of governors to force Sterling to sell the team.
How do you force a sale? The only way would be to ban the Clippers from playing next season, and I really don't see them trying it.
You can't by definition "ban" an owner.
I don't think the NBA can ban a team over an opinion of the owner. The result would be an immediate lawsuit by every team member for interference with contract.
