There’s something inherently compelling about an underdog story. In sports, it’s the magic potion that turns ordinary games into cinematic masterpieces. While regular-season success is commendable, it’s the playoff upsets—the Cinderella stories—that linger in our memories for generations. These are the moments when nobody believed, but the players did. When seedings didn’t matter, and hearts outweighed odds.
Let’s take a journey through some of the greatest playoff runs by underdog teams in sports history. These teams weren’t supposed to make it past the first round. But they did. And then they just kept winning.
1. 2007 New York Giants (NFL) – From Wild Card to World Beaters
Odds stacked against them? Check. A 10–6 regular season that barely squeaked them into the playoffs? Check. A date with the undefeated New England Patriots in the Super Bowl? Oh yeah.
The 2007 Giants entered the postseason as the No. 5 seed in the NFC. They faced road games every single round. But with a tenacious defense, a breakout postseason from quarterback Eli Manning, and a relentless pass rush led by Michael Strahan, they stunned the football world.
Their playoff run culminated in one of the greatest upsets ever: Super Bowl XLII, where they ended the Patriots’ perfect season with a 17–14 win. The “Helmet Catch” by David Tyree is etched in NFL folklore. The Giants weren’t the most talented team that year—but they were the toughest when it counted most.
2. 2011 St. Louis Cardinals (MLB) – Comeback Kings
You could argue the 2011 Cardinals had no business even making the playoffs. With just 15 games left in the season, they were 10.5 games behind the Braves for the final Wild Card spot. But they caught fire, while the Braves collapsed.
Once in the playoffs, the Cardinals took down the heavily favored Phillies and Brewers. Then came the World Series against the Texas Rangers.
Down to their last strike twice in Game 6, the Cardinals rallied both times in one of the most unforgettable games in baseball history. David Freese hit the walk-off homer in the 11th to force Game 7, which St. Louis won handily. From near-elimination to World Champions—this was a storybook ride.
3. 1999 New York Knicks (NBA) – Eighth Seed, Endless Fight
The Knicks were not supposed to make history in 1999. The season was shortened due to a lockout, and New York barely made the playoffs as the No. 8 seed. No eighth seed had ever made the NBA Finals before.
Yet the Knicks bulldozed their way through Miami, Atlanta, and Indiana. Allan Houston’s iconic game-winner against the Heat in the first round set the tone. Even though Patrick Ewing was injured during the Eastern Conference Finals, the team rallied behind Latrell Sprewell, Larry Johnson, and Marcus Camby.
Though they eventually lost to the San Antonio Spurs in the Finals, their improbable run through the East was the stuff of legends—and remains unmatched for an 8th seed.
4. 2012 Los Angeles Kings (NHL) – The Kings of Chaos
Hockey is known for its playoff parity, but the 2012 Kings took the unpredictability to a new level. Entering the Stanley Cup Playoffs as the Western Conference’s No. 8 seed, the Kings went on an unprecedented tear.
They became the first team to defeat the top three seeds in their conference in a single postseason, dispatching the Canucks, Blues, and Coyotes with remarkable ease. Their record? A staggering 16–4. Led by goalie Jonathan Quick’s otherworldly performance and captain Dustin Brown’s physical dominance, they steamrolled their way to the franchise’s first Stanley Cup.
5. 1983 NC State Wolfpack (NCAA Men’s Basketball) – “Survive and Advance”
When it comes to March Madness, no story captures the spirit of the underdog like Jim Valvano’s NC State Wolfpack. The 1983 team wasn’t supposed to be there. They needed to win the ACC tournament just to get into the NCAA bracket.
Then they began a string of nail-biting victories—many decided in the final seconds or overtime. Their path culminated in the national championship game against the high-flying Houston Cougars, featuring future NBA stars Clyde Drexler and Hakeem Olajuwon.
In the closing seconds of a tie game, Dereck Whittenburg’s desperation shot turned into Lorenzo Charles’ miraculous dunk at the buzzer. Pandemonium. Coach Valvano sprinting around the court looking for someone to hug became an iconic image in sports history.
Why We Love Underdogs
These underdog playoff runs remind us why we watch sports in the first place. It’s not just about athletic dominance—it’s about belief. It’s about grit and chemistry and moments that defy logic. They show us that greatness doesn’t always wear a top seed. Sometimes it sneaks in the back door and takes the whole house down.
And in every bar, living room, and stadium, fans rise in collective awe. Because deep down, we all want to believe that on the right day, with the right mindset, anyone can win it all.
That’s the heart of the underdog story. And in the playoffs, it’s pure magic.
