I've lived in Phoenix since 1999, like to pull for the Cardinals, they have been pretty fun to watch for a while. Bills still my main team.
As far as all the negative comments about other teams fans, in my experience at many stadiums around the country, Bills fans are about the most obnoxious and annoying fans around. Bills fans love to tell everyone that they are the greatest fans around, the weather in Buffalo isn't that bad(telling that to fans in San Diego is amusing) and they are loud and obnoxious. They also get too drunk and act stupid.
Look at yourselves in the mirror before criticizing others.
