5. Buffalo Bills vs. AFC East

Alright, this one is a little bit outside the box. The Buffalo Bills have not had rivalries in recent years because, quite frankly, they have been awful. Even last year, the team went 9-7 but hardly was good or scary enough to tick anybody off. The Bills have basically been a franchise lost in the abyss, with nobody outside of western New York caring much about the team or its fate.

Now, all of that has changed. The roster is really good, but most importantly to this piece, Rex Ryan is in Buffalo. When Ryan is your head coach, you are going to make enemies fast. Considering Ryan has already been in the AFC East when he coached the New York Jets for the past six years, he already has ruffled plenty of feathers. Look for him to enrage the masses throughout his tenure with the Bills.
