Rush may have been wrong, or right about the McNabb comment. What difference does it make. those sports announcers are wrong 7 days a week and twice on Sunday.
Rush is not a racist and if he wants to buy a sorry team and has the money, he should be able to do so.
The difference it makes is that he used race to attack the media and then had the audacity to be surprised when it blew up in his face. It really was one of his stupidest moments, starting with the assumption that the reason the press liked McNabb was his race (and thus ignoring decades of the press fawning all over players like McNabb in every way but skin color), through his actually making the comment only a couple of weeks into his new gig when he knew that all his critics were desperately hoping for just that kind of borderline comment they could twist, and then finally doing no form of damage control on his radio show. This is an albatross he volunteered to put around his neck.
What the NFLPA is doing is setting up a nice discrimination lawsuit for Rush.
