For me, to be honest, Washington still draws my ire more than any other team. For me, the teams that draw my ire more than Philly are the following: Washington, Packers (playoff losses), 49ers, Texans, the Steelers, and the Patriots.
For me, Washington just because of the historical nature of the rivalry, even though we own their stadium. Packers, I don't think I need to add much here. Same with the 49ers.
My ire for the Texans drew because I grew up in the Houston area and really grew a dislike for their fans quickly. I can respect Eagles fans more because we at least have a legit rivalry with the Eagles. I've met a lot of Texans fans who are almost as classless as some of the nasty Eagles fans I've met. Just over Christmas, I was visiting my parents (I live in Cleveland, Ohio now), and a Texans fan saw me at a mall walking with one of my best friends, and he just starts running his mouth at me. I wasn't really in the mood to converse, but he just kept trashing the Cowboys in my face. I've never even had that sort of reaction from Eagles fans, and, like I said, I vacation in New Jersey every year. I know a lot of Eagles fans here in Cleveland, and they never come after me like that. I have had more genuinely enjoyable conversations with Eagles fans than I have had with Texans fans.
Do I really need to explain my ire for the Steelers? As for the Pats, it's because they have more Lombardi's than us lol.
