I too hate them all, but over all, yes, the Jets are our biggest rival, they have the most long term success with and against us. Our games with them go all the way back to the 70's, they were cemented in the 80's when we played them in the playoff's and beat them to sweep them one season. Then all the great 50 point a piece games we played some wins some loses with Marino and Richard Todd/Ken O' Brien. Our history against the jets is long term.. I still remember how the Bills went ) for the 80's against us and we had just as much of a strangle hold on the Patriots at one point. It's just within the past decade that either the Bills or Patriots have risen to match us in win's and losses... but the Jets have consistently been right there with us.. Our biggest rival in my eyes will always be the Jets... As a long time Jets fan, and he'll tell you that The Fish are bigger long term rivals than the Bills or Pats..
