patriotsreign, if you really don't care, just don't answer the post. he didn't say anything even remotely rude, so there's no need to throw around insults (which presumably is what you meant by "looser"...)
I think it's actually an interesting question, approaching it from the perspective of a college basketball fan. my school has one true rival, regardless of how good each school is during any given season. and even when one team is significantly better, the matchups still tend to be fairly close, simply because of the intensity and emotion of the rivalry.
we also have teams that sort of "become" our rivals because they're successful and contend for the conference championship. these matchups can get pretty intense, but in the end, when they have down years, people don't care quite as much.
so I guess I would put indy and pittsburgh in the later category, and miami and NYJ would be more our "true rivals". this is mostly based on the fact that, if indy sucked, I really wouldn't care about them that much. but the jets suck, and I still hate them
I really don't have any antipathy towards buffalo- I think after that 4-year stretch of losing in the super bowl, they're hard for anyone to hate.
I don't think the NY-boston feud is as prominent in football as it is in baseball- probably because the giants tend to be the better team, and they're not even in our conference. basketball, hell if I know, last time I watched the NBA the lakers were our rival.
I think, based on my many eagle-fan friends, that the NFC east is unusually intense in terms of rivalries. I can't think of any other division that hates each other nearly that much, maybe the steelers and browns...
anyway, I think I'd go ahead and put the jets number 1 and the dolphins number 2, for long term purposes. right now, it's obviously the colts and steelers.
