It's still 2006 in Colorado. The donk fans I've interacted with are going to have to be put on suicide watch if/when Manning has trouble, they seriously think they're the best team in the AFC.
I get Colts games as my market, having seen most of them in the past 10-11 years I can tell you without a doubt he has slowly declined between 2006-2010. Pre everything else. Is he the best QB in our division? Sure. Is he on the best team? Absolutely not.
