The Patriots were coming off their bye week in the middle of a ten-game win streak that looked like it would easily continue early on their matchup against the Bills on Sunday. They looked every bit like the team at the top of not only the division, but the conference, until the second half, when they completely collapsed.
Josh Allen's efforts allowed Buffalo to steal the win in New England, the way the Patriots did earlier in the season in Buffalo, forcing the divisional champion to be crowned likely in the final game of the year.
