Comparing each NFL team over the last 20 years, we’ve been able to determine the greatest underdog stories of the 21st century and which teams are most often faced with a mountain to climb.

Best Underdog Performers of Last 20 Years

It’s a phenomenon that makes the sport so popular across the country; some NFL teams simply thrive as underdogs, pulling off a result despite not being given a chance. But which teams are best at defying the odds and claiming victory from the least likely of places?

With an astonishing 43.3% win rate against the odds since the turn of the century, the Pittsburgh Steelers are the NFL’s ultimate underdogs, closely followed by the Philadelphia Eagles (40.2%), New England Patriots (39.3%), Tennessee Titans (38.8%), and Denver Broncos (38.8%). Incredibly, though, despite being positioned as underdogs, there are a whopping 10 Super Bowl titles among this group of teams in the 21st century alone — including five since 2014!

Which Teams are the Underdog Most Often?

Focusing our attention on the teams that nobody ever gives hope to, the Arizona Cardinals have played the most games as an underdog this century (395), closely followed by the Detroit Lions (393). Meanwhile, the New York Jets, Cincinnati Bengals, and Super Bowl LV champions Tampa Bay Buccaneers round out the five most common underdogs of the 21st century.

At the other end of the table, the Baltimore Ravens are statistically the number one odds-on team in the NFL, playing just 180 games as an underdog over the last couple of decades, with the Houston Texans (200) and New England Patriots (214) placing second and third, respectively.

NFL Underdog Stories of Last Decade

Analyzing data from the last 10 years, we can reveal the best overachievers of the decade, as well as the teams that have faced the most games as underdogs.

The Best Recent Underdog Performers

As far as recent over-performers go, our research reveals six-time Super Bowl winners, the New England Patriots, as the undisputed top-rated underdogs of the last 10 years, with an impressive 50% win rate when not the favorite. Placing second, the Pittsburgh Steelers are once again among the top over-achievers, winning 49.2% of their games as an underdog over the last decade.

Meanwhile, the New Orleans Saints (45%) also rank highly, in third, with the Seattle Seahawks (44.6%) and Super Bowl LIV winner Kansas City Chiefs (43.3%) close behind. In similar form to the underdogs of the 21st century, the top five over-performers of the last 10 years hold a combined five Super Bowl titles.

Which Teams have been Underdogs the Most in the Last 10 years?

The Cardinals might be the biggest NFL underdog of the last 20 years, but in the last decade, it’s the Jacksonville Jaguars who’ve played the most games as non-favorite (142). The Jags lead the way by some distance, having faced off against statistically better opposition 10% more often than next-placed Washington Commanders (130), who rank just above the Las Vegas Raiders (127), New York Jets (122), Miami Dolphins (118), New York Giants (118), and Cleveland Browns (118).

The top-rated football team of the last decade, meanwhile, has played just 28 games as an underdog, is the New England Patriots. This is made yet-more impressive when you remember they’ve also enjoyed victory in half of these games!

With the Super Bowl just around the corner, will we see an upset in the greatest game of the calendar year?
