12. Buffalo Bills (9-7) | AFC No. 6 seed
Once the Bills get finished thanking the Bengals and reveling in the franchise's first playoff appearance since the 1999 season, they actually must play a game Sunday in Jacksonville. Their chances of pulling an upset are greatly diminished by the ankle injury that threatens to sideline or limit RB LeSean McCoy.
