Three weeks cannot define an NFL season, but the evidence is harder to dismiss. Buffalo, Kansas City, Las Vegas, Minnesota and San Francisco are the five unbeaten teams, each reaching 3-0 through a different formula.
Philadelphia and Seattle fell from that group in Week 3, reinforcing how quickly perceptions can change.
The weekend produced five winning scores in the final three minutes, three double-digit comebacks and another demonstration that quarterback depth can transform a mismatch.
Las Vegas erased an 11-point deficit, Denver stunned Los Angeles, Baltimore won on the final play in Brazil and Washington shocked the defending champions without its starting quarterback. Chicago closed the week by overwhelming Philadelphia behind 38-year-old backup Case Keenum.
These are not September verdicts or reactions to one Sunday. They are five observations supported by performance, personnel and patterns that have begun to emerge across the NFL through three weeks of the 2026 season.
1. The five unbeaten teams have earned their records in different ways
Buffalo, Kansas City, Las Vegas, Minnesota, and San Francisco make up the NFL’s remaining perfect class, but their paths to 3-0 have been anything but identical.
The Bills overcame five turnovers and a 10-0 deficit to defeat the Chargers, 24-16. Josh Allen rushed for two touchdowns for the third consecutive game, becoming one of four players in league history to open a season with multiple rushing scores in each of his first three games. Buffalo also became one of 10 teams since the 1970 merger to begin 3-0 against three opponents that posted winning records the previous season.
Kansas City has demonstrated greater control. After escaping Indianapolis in overtime, the Chiefs limited Miami to 10 points and improved to 3-0 behind another efficient performance from Patrick Mahomes.
San Francisco’s offense has scored at least 35 points in consecutive games. Minnesota continues to win through defense and situational football, holding Tampa Bay to 16 points Sunday.
Then there is Las Vegas, the group’s most surprising member. The Raiders trailed New Orleans by 11 points in the second half, then scored 19 unanswered points to win 35-27. Kirk Cousins threw three touchdown passes, Brock Bowers caught 10 passes for 116 yards and a score in his season debut and the defense forced four turnovers.
Three victories don't guarantee contention, but these records aren't built entirely on favorable bounces. Each unbeaten team has already shown at least one sustainable strength, and the Raiders have shown they belong in the conversation.
2. Quarterback depth is already changing the competitive map
Washington and Chicago supplied the clearest evidence that a credible backup quarterback can preserve far more than one game.
With Jayden Daniels unavailable, Marcus Mariota threw three touchdown passes as Washington stunned defending champion Seattle, 33-31. The Commanders generated only 229 total yards compared with Seattle’s 437, but Mariota protected the football, converted scoring opportunities and gave Washington enough functional offense to capitalize on three Seahawks turnovers.
Case Keenum delivered an even greater surprise Monday night. Making his first regular-season appearance since 2023 in place of Caleb Williams, the 38-year-old completed 24 of 34 passes for 247 yards and two touchdowns while adding a rushing score in Chicago’s 27-7 demolition of previously unbeaten Philadelphia. The Bears controlled possession for nearly 37 minutes, committed no turnovers and forced three. Keenum also tied Ryan Fitzpatrick’s NFL record by winning starts for seven different franchises.
The lesson extends beyond two upsets. New York lost Jaxson Dart on its opening possession against the Rams in Week 2 and produced only six points. The Giants then won without him in Week 3, but needed four Dominic Zvada field goals and a defensive stand to defeat Tennessee, 12-7.
Quarterback depth cannot replicate elite talent, but it can preserve a season. Washington and Chicago were prepared to adjust their identities around experienced replacements. Teams without that flexibility are one injury away from watching an otherwise competitive roster become severely limited.
3. The league’s narrow margins are rewarding resilience and punishing mistakes
Five teams - Baltimore, Cleveland, Detroit, Indianapolis and Pittsburgh - produced a winning score during the final three minutes of the fourth quarter Sunday. Buffalo, Las Vegas and Denver each overcame a deficit of at least 10 points.
Baltimore’s 34-31 victory over Dallas provided the most dramatic finish. After the Cowboys tied the game with seven seconds remaining, Lamar Jackson completed a 27-yard pass to Zay Flowers before Tyler Loop kicked a 56-yard field goal as time expired in the NFL’s first regular-season game in Rio de Janeiro.
Denver rallied past the Rams, 30-26, while Pittsburgh capitalized on a late Cincinnati turnover to win, 30-27. Indianapolis earned its first victory on Spencer Shrader’s 53-yard field goal, and Detroit survived after surrendering a 14-point advantage to the Jets.
Seattle’s defeat illustrated the other side of competitive balance. Jaxon Smith-Njigba caught 10 passes for 128 yards and two touchdowns, helping the Seahawks outgain Washington by 208 yards, but three turnovers erased that statistical dominance.
Early-season comebacks can be dismissed as volatility, but they also show composure. Teams capable of protecting the football, executing in the final two minutes and producing one decisive special-teams or defensive play will continue winning games in which they are not statistically superior.
The NFL’s margin for error remains unforgiving. Week 3 showed that the team controlling most of the game does not necessarily control its outcome.
4. Versatile playmakers are becoming the league’s most difficult matchup problem
The modern NFL increasingly belongs to offensive players who cannot be defined by one position or one assignment.
Jahmyr Gibbs produced 164 yards from scrimmage and three touchdowns in Detroit’s 31-24 victory over the Jets. His game-winning score came through the passing game, where his speed and route-running overwhelmed New York’s linebackers. Gibbs now has five career games with at least three touchdowns, tying Jim Brown and Todd Gurley for the most by a player before turning 25.
Allen remains the ultimate position-less weapon. His rushing ability changes Buffalo’s mathematics near the goal line, forcing defenses to account for the quarterback as both the primary passer and a short-yardage runner.
Bowers immediately changed the Raiders’ offense upon returning from a knee injury. Las Vegas moved him throughout the formation, created favorable matchups and repeatedly gave Cousins a dependable target during its second-half comeback.
Christian McCaffrey surpassed 100 yards from scrimmage again as San Francisco defeated Arizona, 36-30. George Kittle caught two of Brock Purdy’s four touchdown passes, demonstrating how many different defensive problems the 49ers can create from the same personnel grouping.
These are more than productive individual performances. Gibbs, Allen, Bowers, McCaffrey and Kittle force opponents to declare coverages, alter personnel and defend every area of the field. Their versatility creates schematic advantages before the ball is snapped—and those advantages appear sustainable.
5. The AFC is already developing a sharp divide
Buffalo, Kansas City and Las Vegas are 3-0. The Chargers, Dolphins and Texans are 0-3. That early separation has created urgency in a conference where playoff spots were expected to be fiercely contested.
The Chargers have faced a difficult opening schedule, but their loss in Buffalo extended a winless start marked by recurring issues finishing possessions. Miami scored only 10 points against Kansas City and still has not won. Houston fell to Indianapolis, 19-17, despite entering the season with postseason expectations.
A 0-3 record is not mathematically fatal, but it leaves almost no room for a prolonged adjustment period. Since the NFL expanded its postseason field in 2020, recovering from three opening losses has remained exceptionally difficult. Those teams must now play winning football immediately while hoping the conference’s early leaders regress.
Buffalo and Kansas City were expected to contend. Las Vegas changes the equation because its emergence potentially adds another credible AFC playoff challenger. The Raiders have won on the road, protected the football when it mattered and generated pressure without relying heavily on the blitz. They have also shown the ability to rally when their initial game plan fails.
Three weeks do not determine the playoff field, but they can create consequences that last through December. The AFC’s unbeaten teams have established valuable separation, while the Chargers, Dolphins and Texans are no longer dealing with disappointing starts. They are confronting legitimate threats to their seasons.
