If you’ve spent any time scrolling through sports Twitter or screaming at your TV during a Sunday afternoon in mid-January, you know the deal. People love to talk about Patrick Mahomes. They obsess over Travis Kelce. But honestly? The real reason the Chiefs have stayed relevant while their offense hit some serious speed bumps in late 2025 is that weird, complex, and often infuriating defensive unit led by Steve Spagnuolo.
It’s easy to look at a single number and think you understand the kansas city defense ranking. But if you just look at "yards allowed" or "sacks," you’re missing the forest for the trees. This unit is a bit of a statistical enigma. Depending on who you ask—or which spreadsheet you're looking at—the Chiefs are either a top-five juggernaut or a middle-of-the-pack group that's lucky to have a winning record.
The truth is somewhere in the messy middle.
The Numbers Game: Where the Chiefs Actually Stand
As of early 2026, the final regular-season data for the 2025 campaign is in. It tells a story of a bend-but-don’t-break philosophy that would make old-school coordinators sweat.
In terms of Points Against, Kansas City finished the 2025 season ranked 6th in the NFL, allowing roughly 19.3 points per game. That sounds elite. It is elite! Keeping teams under 20 points in the modern NFL is basically like finding a parking spot right in front of the grocery store on a Saturday. It just doesn't happen that often.
But then you look at the Total Yards Allowed, and they slip to 10th. Still good, but not "scary."
Things get even weirder when you dive into the advanced analytics. The Chiefs' Defensive DVOA (Value Over Adjusted) ended the year at 16th. Yeah, exactly average. According to the nerds at FTN Fantasy, the Chiefs' defense actually had a negative DVOA for a chunk of the year, meaning they were slightly less efficient than a league-average unit when you account for the strength of their opponents.

Why the Disconnect?
So, why is there such a massive gap between being the 6th best team at stopping points and the 16th best at "efficiency"?
It’s about the style of play. The 2025 Chiefs defense relied heavily on a few specific factors:
- Long Offensive Drives: The Chiefs' offense, despite its struggles, tended to go on long, soul-crushing drives that ended in field goals. This kept the defense off the field. Fewer snaps for the defense means fewer opportunities for the opponent to score.
- Red Zone Lockdown: When teams got close, Steve Spagnuolo (or "Spags" as everyone calls him) turned into a mad scientist. They were incredible at forcing field goals instead of touchdowns.
- The Sack Drought: This was the most frustrating part of the 2025 kansas city defense ranking. Despite having Chris Jones and George Karlaftis, the team ranked in the bottom half of the league in sacks for most of the season, finishing 20th in sack rate.
They weren't "dominating" teams at the line of scrimmage. They were out-thinking them in the red zone.
Key Personnel: Who Carried the Load?
You can't talk about this ranking without mentioning Nick Bolton. The guy is a vacuum. He finished the season with 154 total tackles, which is just an absurd number. He is the heartbeat of that 4-3 alignment.
Then you have the secondary. Trent McDuffie continued to be one of the most underrated cornerbacks in the league, even if he doesn't rack up the interception totals that get you on SportsCenter. He's a "lockdown" guy in the truest sense—quarterbacks just stop looking his way.
And we have to talk about Chamarri Conner. He's become the Swiss Army Knife of the secondary. Whether he’s playing deep safety, nickel corner, or blitzing off the edge, he’s everywhere. He actually finished second on the team in tackles with 117. That tells you a lot about how much the Chiefs rely on their defensive backs to help in the run game.

What the "Haters" Say
If you listen to the national media, you’ll hear that the Chiefs' defense is "vulnerable." They point to the Week 15 loss where the unit looked slow against a rookie quarterback, or the fact that they struggled to force turnovers.
They aren't entirely wrong. Kansas City ranked 28th in takeaways for a large portion of the 2025 season.
That’s the "luck" element of football. Some years, the ball bounces your way and you lead the league in interceptions. Other years, like 2025, the ball stays on the ground or hits a defender in the hands and falls incomplete. This lack of "big plays" is why the DVOA and EPA (Expected Points Added) metrics don't love this team as much as the scoreboard does.
Breaking Down the 2025 Schedule Impact
Rankings are often a product of who you play. The AFC West wasn't exactly a gauntlet of offensive firepower in 2025. Facing the Raiders and a rebuilding Broncos squad twice a year definitely pads the stats.
However, they held their own against some of the big dogs. They limited the Bills and the Texans to manageable scores, proving that when the lights are brightest, Spagnuolo’s scheme usually holds up.
It’s an "exotic" defense. You’ll see six guys standing at the line of scrimmage, and you have no idea who is coming and who is dropping into coverage. It’s designed to confuse quarterbacks, not necessarily to overpower offensive lines. That’s why the kansas city defense ranking fluctuates so much—it’s a high-variance style of play.

Tactical Reality vs. Fan Perception
Fans usually judge a defense by three things:
- Did we win?
- Did we get a sack?
- Did we get a pick?
By those metrics, the 2025 Chiefs defense felt "okay." But by the metric of "did we give our offense a chance to win," they were world-class. There were at least four games this past season where the offense couldn't get out of its own way, and the defense held the opponent to 13 or 16 points to secure a win.
Honestly, it’s a weird era for the Chiefs. We’re used to the "Legion of Zoom" and high-scoring shootouts. Now, we’re watching a team that wins ugly.
What to Expect Moving Forward
As we look toward the 2026 season, the defense faces some big questions. Spagnuolo is always a name that pops up in head coaching rumors, though he seems content in KC. The age of the defensive line is a concern, too. Chris Jones isn't getting any younger, and they desperately need a consistent second pass-rusher to emerge so they don't have to blitz so much to get pressure.
If they can find a way to increase that turnover margin, this "10th ranked" defense could easily jump into the top three. The talent is there. The coaching is definitely there. It’s just about getting those "bounce of the ball" plays to go their way for once.
Actionable Insights for Chiefs Fans and Analysts
If you're trying to figure out if this defense is actually "good" or just "lucky," keep an eye on these specific indicators:
- Red Zone TD Percentage: This is the most important stat for this unit. If they keep forcing field goals, they stay elite. If they start giving up six points once teams cross the 20-yard line, the season is over.
- Third-Down Conversion Rate: The Chiefs excelled at getting off the field on 3rd and long in 2025 (allowing about a 38% conversion rate). If that slips, the defense gets tired, and the "yards allowed" will skyrocket.
- Turnover Margin: Watch the "Takeaway" column. If the Chiefs can climb from the bottom 5 into the top 15 in turnovers, they become the best team in the NFL again, period.
- Snap Counts for Rookies: Watch guys like Jeffrey Bassa and Ashton Gillotte. The Chiefs' ability to integrate young, cheap talent into Spags' system is the only way they survive the massive contracts of Mahomes and Jones.
Don't let a single ranking fool you. The Chiefs' defense is a complex machine that prioritizes the scoreboard over the stat sheet. It might not always be pretty, but as long as they keep the "Points Against" ranking in the top 10, they’re going to be a problem for the rest of the league.
