Laughing at these conspiracy theorists.
There might be some bias.... there always is, no matter how hard to league tries to fight the image of bias. It is reflected in things like the number of Broncos in the hall of fame or the fact that coastal teams get much more media exposure than inland teams.
But that is simply the result of the fact the people like Roger Goodell, and the nice folks over at ESPN are all human, and capable of error, not some conspiracy.
I will admit, if the Ravens game is called fairly, than the Broncos probably win that game. Or if Rahim or Champ showed up, too, the Broncos probably win the game.
