After a much-needed bye week, the Patriots were immediately tested in Week 15, as they welcomed the Bills for their second matchup of the season, which could have sealed the division in their favor for the first time in six years.
Based on how they played in the weeks leading up to the game, which included a 10-game win streak, it looked like the Bills should be the underdogs on the road. And at first, that looked to be true, as the Patriots went up 21 points going into halftime, only to fall apart in the final two quarters in the most miserable way.
