Rush's entire point was valid, when taken at face value. The media was portraying McNabb as an elite QB, when at the time, he hadn't earned it. Whether or not it was based on his race, who knows? It could've been because he's a good guy. That was, however, another Sports Media related furor over something that wasn't nearly as objectionable as it was portrayed.
Rush was an easy target (insert joke here). He was easily "Borked" off of ESPN, who caved like a house of cards when he achieved exactly the type of attention that they hired him for. For many of the same reasons, BB has been their target this week. They are now attempting to Nixonify BB. Limbaugh and Belichick are both not "one of them", nor do they wish to be. They have virtually no use for them or their uneducated (as Rush and BB see them) opinions. Their success is not related to engendering themselves to the media. They exist and succeed completely outside their dominion, and for that, they must pay.
The media never are held accountable for their completely knee-jerk reactionary posturing. Oh, they can moralize with the best of them, waxing indignant of numerous indiscretions, large and small, knowing full well that their own skeletons are securely stowed away, tidily out of view. Good work if you can get it.
