The Jets Stun the Colts at Super Bowl III – 1969
The 1969 AFL-NFL World Championship Game remains one of the most iconic upsets in sports. The Baltimore Colts entered the contest as heavy favorites, armed with one of the league’s top defenses and a 13–1 record. The New York Jets, led by quarterback Joe Namath, were considered outmatched in nearly every category, and it was expected to be an easy night for the Colts.
Namath came into the game with an air of confidence, and in pregame, he guaranteed a victory that seemed bold, even unrealistic. Yet his confidence translated onto the field, as the Jets controlled the game from start to finish. Their 16–7 win validated the AFL’s competitiveness and altered the course of professional football. The upset helped pave the way for the AFL-NFL merger, proving that belief and execution can overturn expectation.
The Patriots Shock the Rams at Super Bowl XXXVI – 2002
Before the Patriots became the dynasty that they are today, they were underdogs facing one of the most explosive offenses in history. The St. Louis Rams, known as “The Greatest Show on Turf,” were expected to dominate behind quarterback Kurt Warner and a high-powered attack. Few predicted that New England, led by a young Tom Brady and coach Bill Belichick, would have what it takes to create an upset.
The Patriots’ defense forced turnovers and disrupted the Rams’ timing throughout the game. Brady’s composure during the final drive set up Adam Vinatieri’s winning field goal, sealing a 20–17 victory. This not only stunned the league but also marked the beginning of one of the NFL’s most successful eras.
The Giants End the Patriots’ Perfect Season at Super Bowl XLII – 2008
The 2007 New England Patriots entered Super Bowl XLII with a perfect 18–0 record, on the verge of completing an unbeaten season. The New York Giants, 10–6 during the regular season, were expected to be little more than an obstacle on the Patriots’ path to perfection. What followed became one of the greatest games ever played.
New York’s defense pressured Tom Brady relentlessly, while Eli Manning led a late comeback highlighted by David Tyree’s remarkable helmet catch. Plaxico Burress scored the decisive touchdown, giving the Giants a 17–14 win. The upset ended New England’s perfect run and cemented the Giants’ victory as one of the biggest shocks in football history.
The Giants Get One Over the Bills Super Bowl XXV – 1991
The Buffalo Bills were considered the superior team heading into Super Bowl XXV, boasting a high-scoring offense led by Jim Kelly and Thurman Thomas. The New York Giants were without their starting quarterback, Phil Simms, so they relied on backup Jeff Hostetler and a defensive strategy built around controlling possession. Even Giants fans lacked confidence going into the game, and it was expected that they would be going home with another loss.
The Giants executed their game plan perfectly, limiting the Bills’ offensive rhythm and keeping the score close. The game came down to Scott Norwood’s missed field goal in the final seconds, giving the Giants a 20–19 win. The upset was defined by tactical discipline and calm under pressure, proving that precision can overcome raw power.
The Broncos Defeat the Packers Super Bowl XXXII – 1998
Coming into Super Bowl XXXII, the Green Bay Packers were at the peak of their powers after dominating the previous year’s championships. Led by the legendary Brett Favre, the defending champions were widely expected to claim a second consecutive title. The Denver Broncos, under John Elway, had lost multiple Super Bowls and were seen as likely to fall short again.
This time, Denver flipped the narrative. Running back Terrell Davis delivered a historic performance despite battling migraines, rushing for three touchdowns. The Broncos’ 31–24 win not only stunned the Packers but also secured Elway’s long-awaited first Super Bowl victory. It symbolized resilience and redemption for a franchise long haunted by near misses.
The Seahawks Dominate the Broncos Super Bowl XLVIII – 2014
The Denver Broncos entered Super Bowl XLVIII with a record-breaking offense led by Peyton Manning. Many expected a high-scoring contest, but the Seattle Seahawks dismantled that prediction from the opening snap. Their defense, known as the “Legion of Boom,” overwhelmed the Broncos, forcing turnovers and controlling every phase of the game.
Seattle’s 43–8 victory was not just a win but a statement to the rest of the league. It was rare to see an underdog dominate a favored opponent in such a one-sided fashion in a championship setting. The performance redefined perceptions of defensive football in the modern era and marked the rise of a new contender in the NFL hierarchy.
