It most likely wasn't a slip of the tongue. But no one can know for sure.
And that's part of the problem. It's such a stupid issue for overreaction. If the person responsible is found guilty of being purposefully racist, fire him/her. If not, give him/her a warning. Fire him/her. Whatever. But ESPN took it down immediately.
People - like the black dude from the video - seem to want more. They want to know what ESPN is going to do to make things right. Kind of like Don Imus. The guy got fired and rightfully so, but many people wanted blood.
As someone posted on Twitter - Lin is going to own ESPN. Why?
