A boycott would have been the biggest slap in the face to their working class fans. These guys have already cashed multimillion dollar paychecks for the sole purpose of playing a game to entertain working class people, those same working class people are the ones who have paid those multimillion dollar contracts through tickets, merchandise, and watching the games generating advertising revenue.
I understand it would suck having the stigma of working for a racist, but holy fuck, at what point do grown men need to brush off getting their feelings hurt, especially grown men who are multimillionaires for playing a fucking game.
Also Donald Sterling has been a known racist for decades, dude has been sued numerous times for blocking minorities from living in his apartment communities that he owns. Pretty sure these guys already knew they worked for a racist, but now they gotta pretend to be mad to save face for the media.
