1. Cowboys- Rival team, Yankees of football, arrogant organization, etc... I don't see how you can be a fan of a team like the Yankees, Lakers, Cowboys, etc.
2. Falcons- Overrated, I hate Vick and how everyone loves him just because the media hyped him up, and the fact that Atlanta is probably the worst pro sports city, especially of those that have all 3 pro sports (hockey doesn't count it's going down anyways the arenas are empty during games lol)
3. Raiders- Similar reasons for hating the Cowboys.
4. Colts- Outside of Manning, I hate this team, and I am currently from Indiana. I have liked Peyton since he was at Tennessee (my dad is a big Tennessee fan), and I don't get why people start hating players just because of the team they play for (i.e. Texas+Texans fans now hating Vince Young just because he plays for the Titans... What if he all of the sudden got traded to say the Buccaneers or something, then you would all of the sudden like him again, right?
)
5. Eagles- Their fan base is probably among the most ignorant in all of sports yet they will cry if there is ever a debate about best sports city/fans and they are not in the discussion. They think they are the best fans but they are up there with the worst. A couple of weeks ago on Mike and Mike in the morning they were talking about this same thing saying how stupid Philly fans are because Art Schell had a better fan approval rating than Andy Reid.
