The list of biggest NFL rivalries starts with the classics: Cowboys vs. Eagles, Bills vs. Dolphins, and Chiefs vs. Raiders. But according to Ozoon Sportsbook own betting data, Cowboys vs. Ravens and Lions vs. Packers (or perhaps Lions vs. Bears) are shaping up to be the rivalries Canadian bettors care about most this coming season.
What ultimately separates the true NFL rivalries from ordinary matchups comes down to three things: frequency, proximity, and stakes. Divisional games are the most intense NFL rivalry games; these teams meet twice during the regular season, often with division titles or Wild Card berths hanging in the balance. Pile up enough of those high-stakes meetings between neighbouring fanbases, and the rivalry stops being just about football – it becomes its own cultural phenomenon, pulling in casual fans who don’t otherwise pay that much attention to the sport. That intensity drives Canadian bettors to the NFL odds board here at Ozoon. Rivalry games are consistently among the most heavily bet matchups of the season, with emotions running high and the outcome always in doubt until the final whistle. Let’s take a quick look at each of the rivalries on our list, starting with arguably the biggest of them all:
Cowboys vs. Eagles
The NFC East is football’s glamour division, with four of the game’s most recognizable brands battling it out. The playoff implications are massive; each of these four teams has won the Super Bowl at least twice, with Dallas (5) at the top of the mountain. These games often get played in prime time for maximum exposure – Monday Night Football will be in Philadelphia for Week 7 – and they’re perfect for American Thanksgiving as well, with Dallas playing host in Week 12.
Bills vs. Dolphins
Moving to the AFC East, we have a rivalry with a unique contrast in conditions: cold-weather Buffalo versus sunny Miami. These two teams were originally in the AFL Eastern Division, so they’ve been battling it out since the mid-1960s; one or the other won every AFC East title between 1988 and 1995, and the stakes are high once again after Buffalo’s recent five-year stay atop the division standings.
Chiefs vs. Raiders
The AFC West also has its roots in the old American Football League, where it was born in 1960 as the AFL Western Division. These teams have moved since then – the Dallas Texans are now in Kansas City, and the Oakland Raiders are in Las Vegas – but that hasn’t dampened their rivalry one bit. The Raiders were ascendant in the ‘60s, ‘70s and early ‘80s; now they’re trying to spoil K.C.’s hopes of regaining the AFC West title, which they won every year from 2016 to 2024 inclusive.
The Rivalries Ozoon Data Says to Watch This Season
All three of these epic rivalries have decades of history behind them. But what about today? Whenever two of the most popular teams in the NFL meet, you know there will be heavy betting on both sides – and according to Ozoon’s betting data, Buffalo, Kansas City and Philadelphia are joined by the Detroit Lions and Baltimore Ravens on the Top 5 list for Canadian bettors. Here are the key matchups to watch out for this season for our newcomers:
Cowboys vs. Ravens
They’re not even division rivals, so Dallas and Baltimore normally meet once every four years during the regular season – but the schedule-makers didn’t want to wait until 2028 to bring these two clubs back together. They’ll see each other in Week 3 for the NFL Rio Game in Rio de Janeiro, Brazil; the betting action will be hot and heavy with QB Dak Prescott leading the Cowboys and QB Lamar Jackson responding for Baltimore.
Lions vs. Packers/Bears
Now we’re cooking with gas. The NFC North features the oldest rivalries in the league, and the Lions (born in 1928 as the Portsmouth Spartans) are just across the border from Windsor, Ontario. They’ll be in the crosshairs of Canadian bettors all season long, but especially when it’s Lions vs. Packers (b. 1919) and Lions vs. Bears (b. 1920), Detroit looking to complete a remarkable worst to first turnaround after finishing last in the division in 2025.
How NFL Policy Shapes Rivalry Matchups
The schedule format ensures that NFL rivalry games like Cowboys-Eagles and Bills-Dolphins are baked into every season, while matchups like Cowboys-Ravens are rare treats – as are the intra-city games between the New York Giants and New York Jets, and the Los Angeles Rams versus the Los Angeles Chargers. Geography alone makes those rivalries interesting; however, the eight divisions (also built on regional lines) kick it up several notches, with playoff implications for nearly every game these rivals play.
Biggest NFL Rivalries FAQ
Not always – NFL scheduling often places metro-area teams in different conferences, so many of the biggest rivalries (such as Bills vs. Dolphins) form through divisional alignment rather than pure proximity.
Division rivals play each other twice per regular season – usually once at home and once away, although “international” games at neutral locations like Rio de Janeiro are eating up more and more of the NFL schedule.
They’re based on which teams Canadians actually bet on most at Ozoon, rather than historical head-to-head competition; Cowboys vs. Ravens is the most obvious example this season.
Rivalry games tend to be closer and less predictable than the point spread suggests, which further drives the ongoing narrative between the two rivals in question – and helps them draw some of the heaviest betting interest at Ozoon.
