Every few years, an NFL defense comes along that makes us wonder if we’re watching something historic.
The 2013 Seahawks did it.
The 2008 Steelers did it.
The 2019 Patriots did it for stretches.
And inevitably, the comparisons begin.
But more than a quarter-century into the 21st century, one defense remains the standard everyone else is chasing.
The 2000 Baltimore Ravens.
Not just because they won the Super Bowl. Not just because Ray Lewis was in the middle of it all. Not just because of the names, the swagger or the reputation that has only grown with time.
Because the numbers remain almost ridiculous.
The Ravens allowed 10.3 points per game during the 2000 regular season.
Look at the best defenses this century and nobody else is particularly close.
The 2000 Tennessee Titans rank second at 11.9.
The 2002 Tampa Bay Buccaneers, another defense remembered among the greatest ever assembled, allowed 12.3.
The 2005 Chicago Bears and 2006 Ravens are next at 12.6.
Then come the 2001 Bears at 12.7 and 2001 Steelers at 12.8.
All historically dominant defenses.
Baltimore allowed barely 10.
Think about that in the context of the modern NFL.
We live in an era designed to produce offense. Rules protect quarterbacks and receivers. Offensive coaches spread defenses across the field. Fourth-down aggression has increased. Passing statistics that once seemed extraordinary have become routine.
Yet nobody this century has seriously threatened what Baltimore did in 2000.
And the Ravens didn’t stop dominating once the playoffs began.
That is what separates the truly legendary defenses from the statistically great ones.
Plenty of teams on this list went home without a Lombardi Trophy.
The 2001 Steelers allowed just 12.8 points per game. No championship.
The 2005 Bears allowed 12.6. No championship.
Baltimore itself produced another suffocating defense in 2006, also allowing 12.6. That team didn’t win it all, either.
The 2008 Titans gave up 14.6 points per game and went 13-3. They were eliminated in their first playoff game.
The 2009 Jets rode one of football’s best defenses to the AFC Championship Game but stopped there.
The 2011 49ers allowed 14.3 and reached the NFC title game. The 2011 Steelers were even stingier at 14.2.
Neither reached the Super Bowl.
That’s football’s cruel reminder that a great defense can carry you a long way.
It cannot guarantee the final step.
Some defenses, however, finished the job.
The 2002 Buccaneers allowed 12.3 points per game, then demolished the Raiders in Super Bowl XXXVII.
The 2003 Patriots surrendered 14.9 and won the championship.
The 2008 Steelers allowed 13.9 and finished their season with James Harrison producing perhaps the most famous defensive play in Super Bowl history.
Green Bay’s 2010 championship team allowed 15.0.
And then there were the 2013 Seahawks.
Seattle’s Legion of Boom gave up 14.4 points per game before providing the exclamation point in the Super Bowl, overwhelming Peyton Manning and a Denver offense that had just set an NFL scoring record.
Seattle’s 43-8 victory remains one of the great defensive statements in Super Bowl history.
But Baltimore’s 2000 run was something else entirely.
Those Ravens didn’t merely have a good defense supporting a championship team.
The defense *was* the championship team.
Baltimore went five consecutive games during the regular season without scoring an offensive touchdown.
Five.
And somehow won two of them.
That tells you almost everything you need to know about the burden placed on the Ravens’ defense.
Lewis was the centerpiece, but this wasn’t a one-man operation. Tony Siragusa and Sam Adams clogged the middle. Peter Boulware attacked from the outside. Rod Woodson brought Hall of Fame experience to the secondary.
They didn’t simply stop teams.
They strangled games.
Baltimore allowed 165 points during the entire 16-game regular season. Opponents scored only 10 touchdowns on the ground all year. The Ravens went five games without allowing an offensive touchdown.
Then the playoffs started and somehow the defense became even more imposing.
Denver scored three points.
Tennessee scored 10.
Oakland scored three.
And in Super Bowl XXXV, the New York Giants failed to score a single offensive point.
Baltimore won 34-7, with New York’s only touchdown coming on a kickoff return.
Four playoff games.
One offensive touchdown allowed.
That isn’t just championship defense.
That’s domination.
And maybe the best evidence of Baltimore’s greatness comes from looking at what happened afterward.
The NFL has spent the ensuing decades becoming increasingly tilted toward offense.
And yet elite defenses have continued to emerge.
Pittsburgh appears repeatedly among the century’s best, with its 2001, 2008, 2010 and 2011 teams all on the list.
Baltimore returned with outstanding groups in 2006 and 2008.
New England appears three times.
Chicago, Philadelphia and Tennessee each appear twice.
Seattle built the Legion of Boom.
Still, nobody got to 10.3.
Nobody really came close.
That’s why, whenever another dominant NFL defense emerges, the question shouldn’t simply be whether it is the best defense in the league.
The question is whether it belongs in the conversation with Baltimore.
The 2002 Buccaneers have an argument.
So do the 2008 Steelers.
The Legion of Boom Seahawks certainly do.
Different eras. Different rules. Different styles.
But if we’re talking about the best defense of the 21st century, the numbers point toward Baltimore.
So does the championship.
And so does what happened when the games mattered most.
Twenty-five years later, the 2000 Ravens remain where they were when that unforgettable season ended.
On top.
