by In football, scoring points gets all the attention. But championship teams are built on defense.
A great defense doesn’t just stop the other team. It forces turnovers, creates fear, and changes the entire game.
Throughout NFL history, some defenses were so good that people still talk about them decades later.
These units had legendary nicknames like “Steel Curtain,” “Purple People Eaters,” and “Legion of Boom.”
They combined speed, strength, and smart play-calling. They had Hall of Fame players who became household names.
From the 1960s to today, NFL defenses have evolved. Old-school units focused on stopping the run. Modern defenses must handle fast, pass-heavy offenses.
But the best defenses share one thing: they dominate opponents and win championships.

Top 20 Best NFL Defenses of All Time

The 2000 Ravens built the best defense of the modern era.
They allowed only 165 points all season — just 10.3 per game. That’s less than two touchdowns!
Ray Lewis was the heart of this defense. He won Defensive Player of the Year with incredible tackles and leadership.
The front seven stopped the run completely. No team rushed for 100 yards against them all year.
Key Stats:
- 23 interceptions (defense created turnovers constantly)
- 6 defensive touchdowns in regular season
- Held playoff opponents to just 16 offensive points total
- Won Super Bowl XXXV, beating the Giants 34-7
The Ravens showed that defense alone can carry a team to a championship. Their offense went five games without a touchdown, but the defense kept winning!
This unit set the standard for how dominant a defense can be.
#2: 2002 Tampa Bay Buccaneers – “Tampa 2”
The Bucs revolutionized defense with the Tampa 2 scheme.
This system used fast linebackers to cover passing lanes while safeties played deep.

The Tampa 2 scheme is still used by NFL teams today. That’s how influential this defense was.
#3: 1971 Minnesota Vikings – “Purple People Eaters”
The Vikings’ defensive line was so scary, they got nicknamed after a monster song!
The “Purple People Eaters” were Alan Page, Jim Marshall, Carl Eller, and Gary Larsen.

Transition: How Defense Evolved from the 1960s to 1980s
Early NFL defenses relied on size and strength. The 4-3 alignment was king.
But in the 1980s, coaches got creative. Buddy Ryan’s 46 defense and Bill Belichick’s hybrid schemes changed everything.
Defenses started blitzing from different angles. Linebackers became pass rushers. The game sped up!
