"Commissioner Silver thank you for protecting our beautiful and powerful league!! Great leader!! #BiggerThanBasketball #StriveForGreatness," James wrote on Twitter Tuesday, April 29, 2014, after Silver announced that Los Angeles Clippers owner Donald Sterling has been banned for life by the league, in response to racist comments the league says he made in a recorded conversation.
