The Greatest Upsets in NFL Playoff Bracket History
Some upsets stand above all others in NFL playoff bracket history. The 2007 New York Giants beating the undefeated New England Patriots in Super Bowl XLII shocked everyone. The Patriots had gone 18-0 and looked unstoppable. The Giants were a wild card team that barely made the playoffs. But New York's defense harassed Tom Brady all game, and Eli Manning made miracle throws. David Tyree's helmet catch remains one of the most famous plays ever.
Another massive upset happened when the 2010 Green Bay Packers won the Super Bowl as a six seed. The Packers had to win three straight road games just to reach the championship. They beat the top seeded Atlanta Falcons, then defeated Chicago and Pittsburgh. Aaron Rodgers played perfectly in all three games. The 2012 Baltimore Ravens also shocked brackets by winning as a four seed with an aging roster.
Wild Card Weekend Shockers That Changed NFL Playoff Bracket History
Wild Card Weekend produces more upsets than any other playoff round. The 2010 Seattle Seahawks provided the most shocking Wild Card upset in NFL playoff bracket history. Seattle finished 7-9 and barely won their division. They hosted the defending champion New Orleans Saints who had won 11 games. Nobody gave Seattle a chance to win.
But Marshawn Lynch broke tackle after tackle on his famous Beast Quake run, and Seattle won at home. The 2017 Jacksonville Jaguars shocked the Pittsburgh Steelers in the Divisional Round after upsetting expectations all season. Jacksonville's defense dominated Ben Roethlisberger and the Steelers offense. The 2019 Tennessee Titans beat the New England Patriots and Baltimore Ravens on the road as a six seed. Derrick Henry ran over both teams with powerful rushing performances that nobody could stop.
Division Rivalries That Created NFL Playoff Bracket History
Division rivals know each other so well that upsets happen frequently when they meet in the playoffs. The 2009 New York Jets traveled to face their division rival New England Patriots in the playoffs. Nobody expected the Jets to win, but they dominated the Patriots at home. Rex Ryan's defense confused Tom Brady all game long.
The 2014 Dallas Cowboys lost to the Green Bay Packers in a controversial finish that included the famous Dez Bryant catch that was ruled incomplete. Cowboys fans still argue about that call today. The 2018 Philadelphia Eagles beat the Chicago Bears in the Wild Card round despite losing Carson Wentz to injury. Nick Foles led the Eagles on an improbable run. These division matchups create extra intensity because teams play each other twice during the regular season already.
Quarterback Performances That Shocked NFL Playoff Bracket History
Unknown or backup quarterbacks sometimes create the biggest surprises in NFL playoff bracket history. Nick Foles replaced injured Carson Wentz late in the 2017 season and led Philadelphia to a Super Bowl championship. Foles played nearly perfect football in the playoffs. He outplayed Tom Brady in Super Bowl LII and caught a touchdown pass on the famous Philly Special trick play. Joe Flacco had an average regular season in 2012 but became unstoppable in the playoffs.
He threw 11 touchdowns and zero interceptions during the Ravens championship run. Kurt Warner came from stocking shelves at a grocery store to winning Super Bowl XXXIV with the Rams. His Cinderella story remains unmatched. Eli Manning beat Tom Brady twice in Super Bowls despite never being considered an elite quarterback. His playoff performances exceeded his regular season play dramatically.
Defensive Dominance That Rewrote NFL Playoff Bracket History
Great defensive performances create upsets by shutting down high powered offenses. The 2000 Baltimore Ravens defense might be the greatest playoff unit ever. They allowed just 23 points in four playoff games and carried Trent Dilfer to a championship. The 2002 Tampa Bay Buccaneers defense destroyed the Oakland Raiders in Super Bowl XXXVII. Tampa Bay returned three interceptions for touchdowns and made Rich Gannon look helpless.
The 2015 Denver Broncos won a championship despite having a struggling Peyton Manning at quarterback. Denver's defense carried the team by pressuring quarterbacks and forcing turnovers. Von Miller dominated Super Bowl 50 with multiple sacks and a forced fumble. The 2007 Giants defense mentioned earlier only allowed 14.3 points per game during their playoff run. They sacked Brett Favre, Tony Romo, and Tom Brady repeatedly.
Coaching Decisions That Changed NFL Playoff Bracket History
Bold coaching moves sometimes create the biggest surprises in playoff games. Bill Belichick's decision to not give the ball to Marshawn Lynch in Super Bowl XLIX led to Malcolm Butler's interception. Seattle should have run the ball but threw instead. Doug Pederson calling the Philly Special on fourth down in Super Bowl LII showed incredible confidence.
The trick play worked perfectly and gave Philadelphia momentum. Pete Carroll's fake field goal against the Packers in the 2014 NFC Championship helped Seattle rally from a huge deficit. John Harbaugh's aggressive fourth down calls during the Ravens 2012 run kept drives alive. Andy Reid's time management problems have cost Kansas City in several playoff games over the years. These coaching moments show how strategy impacts outcomes just as much as talent does.
Appreciate Every Moment of NFL Playoff Bracket History
The greatest upsets and surprises prove that anything can happen once the playoffs start. Underdogs find ways to win when nobody believes in them. Backup quarterbacks become heroes. Great defenses shut down explosive offenses. These moments become part of NFL playoff bracket history that fans remember forever.
