AFC East
In terms of number of games played, the Patriots have competed most against other teams in the AFC East division: the Buffalo Bills, Miami Dolphins, and New York Jets, who were all a part of the AFC East division since the AFL-NFL Merger, as well as the former AFL Eastern division. The Patriots also share rivalries with several teams outside of their division, including the Indianapolis Colts, who were members of the AFC East from 1970 to 2001, the Baltimore Ravens, the Denver Broncos and the Pittsburgh Steelers.
