The Buffalo Bills have significant NFL rivals, notably the Miami Dolphins, New England Patriots, and Kansas City Chiefs. The Dolphins, the oldest and most renowned Bills rival, entered the league six years after the Bills, fostering consistent competition. The Dolphins hold a 62-56-1 record against the Bills and have won two playoff games. The rivalry draws from city differences and key games, like the 1966 54-24 Bills victory and the 2021 56-24 win. The Patriots, another major rival, began in the league simultaneously with the Bills, engaging in 126 contests. With a 77-49-1 record, the Patriots dominated the series with Tom Brady and Bill Belichick. The Chiefs, a newer rival, have intensified the rivalry recently. Formerly the Dallas Texans, they shifted to Kansas City in 1963. The Bills lead with a 28-24-1 record in 53 games played. Emerging in the 1960s AFL era, this rivalry showcased memorable playoff games like the 1993 32-point Bills comeback and the 2000 "Music City Miracle." The current competitiveness of this rivalry stems from both teams' strong AFC standings.
