For the last five years, thanks to Tom Brady's departure from the division, the Buffalo Bills have reigned supreme in the AFC East, winning the division each season. That was projected to continue this season, since many analysts keep moving the goalposts on their Championship window, but it has not come to fruition this year because of the New England Patriots.
Despite most predictions suggesting they would win only a few more games than they have over the last two seasons, they have defied the odds and are currently on a seven-game win streak, with their latest win coming on the road against the Tampa Bay Buccaneers.
