The Buffalo Bills are one of 12 NFL franchises to never win a Super Bowl in spite of winning the conference in four consecutive seasons in the early 1990s. In the Bills' 60-year history (dating back to the time before the AFL-NFL merger), they have developed a few rivalries.

5. Cleveland Browns

Two Great Lake cities, the Cleveland Browns exist as a minor rival for the Bills, with Buffalo going 9-12 all-time in the regular season against the AFC North club. Additionally, the Bills lost to the Browns in the divisional round of the AFC playoffs in Jan. 1990.

The Browns and Bills also saw ugly games played during overlapping bad years as NFL franchises, characterized by low-scoring games while Cleveland and Buffalo were the laughingstocks of the league.

Before all of that, the Browns were big rivals of the AAFC's Buffalo Bills, a different franchise with the same name until Cleveland joined the NFL and the former Bills had to fold.

4. Tennessee Titans/Houston Oilers

The only other non-division rival, the Tennessee Titans joined the AFL with the Bills as the Houston Oilers (the Oilers relocated to Tennessee in 1997). Star quarterback Warren Moon and Jim Kelly and the Bills had notable clashes, most famously the 32-point overtime victory for Buffalo in the 1992-93 wild card round. The Bills previously beat Houston in the divisional round by a touchdown in New Year's Day 1989.

The third postseason matchup between the two franchises featured the “Music City Miracle,” with Steve McNair and the Titans beating the Bills in the wild card on Jan. 8, 2000, when Kevin Dyson scored on a kickoff return in the final seconds on a lateral pass from Frank Wycheck. The Bills didn't make the playoffs for another 18 years after that devastating loss.

3. New York Jets

The Bills and New York Jets share a state (kind of) and a lot of the off-the-field part of this rivalry comes with Western New York vs. the New York City area. Buffalo possesses a 62-56 record against the Jets in the regular season while beating them in the two franchises' one and only playoff matchup (a four-point victory on the road in Dec. 1981).

Additionally, the Jets also saw ex-head coach Rex Ryan accept a job with Buffalo right after getting fired in Jan. 2015 and the Bills select a quarterback, Josh Allen, in the first round of the 2018 NFL Draft after Gang Green selected USC's Sam Darnold.

Allen and Darnold, if they stay in the AFC East, could prove to be a dynamic rivalry on the gridiron for years to come.

2. New England Patriots

The New England Patriots, with Tom Brady under center, have tormented the Bills for the better part of two decades. Bill fans in Western New York have long hyped up their yearly home game against the AFC East foe with tailgating and anticipation (including throwing obscene objects onto the field).

The Bills lost to the Patriots in the pre-Super Bowl era in the two teams' only playoff meeting, but Buffalo and New England's rivalry mostly comes from the twice-a-year matchups and vitriol thrown at the Foxborough franchise during Brady's reign coinciding with Buffalo's 18-year postseason absence.

Additionally, the Bills have gone 43-75-1 against the Patriots in the regular season, a lopsided affair with no less hate for the other side, however.

1. Miami Dolphins

The Miami Dolphins are the Bills' biggest rival. Two very different cities for the franchises—sunny and pleasant Miami vs. cold, wintry, and harsh Buffalo on Lake Erie—the Dolphins long dominated the divisional rivalry in the regular season during Don Shula's tenure as head coach.

The Bills have the edge in the two teams' playoff matchups, though, winning three out of four meetings—all four occurring within eight years in the 1990's. Buffalo won three in a row, twice in the wild card round, once in the divisional round, and meeting in the 1992-93 AFC title game, where Marv Levy and Company would later lose a third consecutive Super Bowl.

In the regular season, the Dolphins have gone 60-47-1 against the Bills, and both find themselves in the open AFC East with perhaps the Patriots' dynasty years over. It could be a reigniting of the fierce '90s rivalry between the Jim Kelly and Dan Marino teams.
