Ranking the 15 Best Defensive Teams in NFL History

The NFL has seen countless dominant defenses over the years, but a few stand out as all-time greats.

Here’s our ranking of the 15 best defensive teams in NFL history.

15. 2008 Pittsburgh Steelers

The 2008 Steelers led the NFL in total defense and points allowed per game. Led by James Harrison, Troy Polamalu, and a ferocious front seven, this team carried Pittsburgh to a Super Bowl XLIII victory.

14. 2015 Denver Broncos

The Broncos’ defense was instrumental in their Super Bowl 50 victory, stifling both Tom Brady in the AFC Championship and Cam Newton in the Super Bowl. In fact, Von Miller’s MVP performance epitomized this group’s excellence.

13. 1976 Pittsburgh Steelers

The “Steel Curtain” reached its peak in 1976, allowing just 28 points over their final nine regular-season games. While injuries derailed their playoff hopes, this unit remains one of the best ever.

12. 1986 New York Giants

Lawrence Taylor’s MVP season was the centerpiece of a defense that dominated en route to a Super Bowl XXI victory. Simply put, Bill Belichick’s schemes made this team nearly unstoppable.

11. 1969 Kansas City Chiefs

The Chiefs’ defense powered them to victory in Super Bowl IV, allowing just 6.7 points per game during the postseason. Led by Hall of Famers like Buck Buchanan and Willie Lanier, this team was ahead of its time.

10. 1977 Atlanta Falcons

Nicknamed the “Grits Blitz,” this Falcons defense set a record for fewest points allowed in a 14-game season (129). Though their offense struggled, their defense was historically good.

9. 1991 Philadelphia Eagles

The “Gang Green” defense led the NFL in rushing, passing, and total defense — a feat no other team has accomplished. Reggie White and Jerome Brown were unstoppable forces.

8. 2002 Tampa Bay Buccaneers

With Hall of Famers Derrick Brooks, Warren Sapp, and John Lynch, the Bucs’ defense dominated the league. They capped their season with a blowout win in Super Bowl XXXVII, where their defense scored three touchdowns.

7. 1975 Los Angeles Rams

This Rams team allowed just 9.6 points per game during the regular season, the best in the Super Bowl era. Their pass rush, led by Jack Youngblood, was unmatched.

6. 1984 San Francisco 49ers

The 49ers’ defense complemented their offense perfectly, allowing just 14.2 points per game and securing a Super Bowl XIX victory. Ronnie Lott was the heart of this stellar unit.

5. 2013 Seattle Seahawks

The “Legion of Boom” redefined defensive football in the modern era. Richard Sherman, Kam Chancellor, and Earl Thomas anchored a secondary that dismantled Peyton Manning’s record-breaking offense in Super Bowl XLVIII.

4. 1962 Green Bay Packers

Vince Lombardi’s Packers were defined by their defense, which allowed just 10.6 points per game. With Herb Adderley and Willie Davis leading the way, this unit set the standard for greatness.

3. 1972 Miami Dolphins

The “No-Name Defense” often gets overshadowed by the Dolphins’ perfect season, but their dominance was a key factor. They led the league in points and yards allowed, securing their place in history.

2. 1985 Chicago Bears

Often regarded as the gold standard of defensive dominance, this Bears team isn’t at number one because of how much the league has evolved. However, there’s no denying the “46 Defense”— led by Mike Singletary, Richard Dent, and coach Buddy Ryan — revolutionized defensive football.

1. 2000 Baltimore Ravens

Arguably the best single-season defense ever, the 2000 Ravens allowed just 165 points across 16 games. Ray Lewis led this unit to a Super Bowl XXXV win, solidifying their place in history.
