I think we're quick to assume it's bias when it could really just be good ol' incompetence. Michaels and Collinsworth are too self-absorbed to bother listening to what anyone else has to say.
Or that SI story that accused the Patriots of warm drinks and whatnot. There was a part about how BB must have people at the airports watching teams arrive so he knows who is classified as "out" the night before. Except for the fact that traveling teams must report non-travelers automatically as "out" to the league the night before. A simple routine procedure, yet national writers (don't call them journalists, they're not) don't know about it, twist it into something sinister, when really, it's their own incompetence and ignorance.
It's incredible how low the bar is to cover major sports on a national level. Actually, the bar has to be low to trip any competent people from participating, so only the snakes and lowlifes can slither under it.
