I live in Lynchburg, VA, which is No Man's Land for NFL football. Everyone down here is all about Virginia or Virginia Tech (meh), and then there's a weird mix of Redskins, Steelers, and Cowboys fans. Very few people root for Carolina or Tennessee. The guy who owns the bar that hosts our Backers group is a Miami fan--but he's from FL, so that's explainable. He told me that this market tends to follow the "national" NFL teams and teams that play in the Super Bowl, which explains the Pittsburgh and Dallas fans. In our Backers group, we have native Virginians who are lifelong Bills fans. Reason? Bruce Smith (V. Tech), the playoff and Super Bowl appearances, and more recently, EJ Manuel (Virginia Beach native).
In this market on an average Sunday, CBS is going to carry the Steelers, Jags, or (rarely) Indy game, and FOX will carry Washington, Carolina, or Dallas. This is a bit of a generalization, but in most cases that's who you get to choose from on network TV on Sundays.
Before I moved here in 2009, I lived in New Hampshire for 25 years. That did nothing but heighten my dislike for the Patriots** and their fans. At first, they were the lovable lugs. Nobody in NH actually wore Patriots gear, and you could go to Foxboro and get a great seat day of the game. The Pats** fans tailgating were jerks, but respectful jerks. When the Brady*/Belichick* era began, there was so much bandwagon boarding that they had to reinforce the thing with steel girders. Then the invisible Pats* fans became d-cks, and the Pats* fans who were already d-cks became really obnoxious d-cks.
