Even I know never to bet on the Browns.. Bills as well. Vikings now as well. Though I know the Vikings can be ok, but that's my husband's team so it's my wifely job to cheer against them.

Steelers/Ravens is a big one. All the NFC East teams hate each other (though I believe the Giants don't really hate the Redskins all that much...Cowboys hate the Skins though). Ask obi who the 49ers rivals are

Hey now, the Bills went to four Super Bowls in a row. But yeah, don't bet on them because they'll do exactly what you think they won't do. Hell, people had them as an early trendy pick to at least hit the playoffs, but last week's stinker says otherwise.

Last year when they started strong, a Buffalo psychiatrist took out ads in the paper saying, "You know eventually the Bills will let you down. Schedule December appointments today!"

That's hilarious.

@Celtic - Bears/Packers is the only rivalry that matters . . . to me anyway :)

My friends have a split basement bears on one side packers on the other, She is a packer fan he is a bears fan - there two kids are stuck in the middle, for all I know when they get old enough they'll probably just root for some AFC team haha

49ers/packers is a good rivalry based on, historically good teams, meeting in the playoffs

*their - oof cant believe I did that

Bills-Dolphins was the biggest rivalry in the NFL in the 90s, anyway. Probably Jets-Pats is the biggest now. The coaches & players openly despise each other.

^ There we go, I was wondering when we'd get some canadian teams!

Football is whack now anyway. Rivalries are dead.

"Greatest NFL Rivalry" =/= "Greatest CFL Rivalry"

Packers/Bears is best.

Patriots/Colts was never a true rivalry. It was more Belichick/Dungy, and once Dungy left, it died a bit. They tried to resurrect it as Peyton/Brady but we all know how that one ended up. They worked at it, but in all honesty, the Colts don't and probably won't have a rival considering how much they suck and their division sucks for at least another three or four years.

Steelers/Ravens and 49ers/Packers are good. I like NYG/Dallas but Dallas has become a giant Hollywood show lately so I try and stay away from them. Kind of how I try and stay away from the Jets but ESPN is so mindfucked that I can't.

Big rivalry of old was Jets/Colts (we've all seen the near b/w Super Bowl) when it was Namath playing his best. Hasn't been that way in a long time though.

Steelers/Bengals ever since the low blows in that play off game that took out Carson Palmer and turned him into a nervois Nellie (he was never the same again) and our top receiver in the first couple.of plays. But it seems the Bengals aren't showing their promise this year.
