Let's not be blind here, would he make that comment about a white guy? Doubtful. I don't think Gruden will lose his job, I don't think he should. But 2011 isn't that long ago and it was a stupid thing to say and quite offensive. It seems that for some people, those getting offended by a terrible statement are the problem, not the person saying it.
It seems like the league and the Raiders are dealing with it quietly, internally, which is appropriate. People like you are the ones overreacting. This will play out and we'll get a resolution, then it's fair to debate. But to get upset because people don't react the way you want them to is pretty silly.
