I truly believe there is a major re-shuffling coming at the top of the NFL over the next few seasons. Many of the "typical" teams at the top are going to have QB/leadership changes, (Pittsburgh, NE, Chargers, Giants, Green Bay, Saints (soon) etc) while others are starting to quickly re-build and will be in the play-off mix starting this season. (Bills, Browns, Jets, 49'ers, Raiders? etc)
To me it really seems like there will be a major shift in the perennial play-off picture over the next couple of seasons and I really hope the Bills will be part of that new group of power-houses. The pieces are definitely starting to come together.
