If you spent any time watching the NFL this past season, you probably noticed a trend that made defensive coordinators want to pull their hair out. Some teams just looked like they were playing on ice. Defensive backs were slipping, safeties were taking angles that made no sense, and quarterbacks were putting up numbers that looked like they belonged in a video game. When we talk about the worst passing defense 2024, it isn't just about one bad game. It’s about a systemic failure that haunted several franchises from September through January.
Pass defense is hard. The rules are basically written to help receivers.
But some teams made it look impossible. Honestly, watching the Jacksonville Jaguars or the Baltimore Ravens (at least early on) try to defend the deep ball was a bizarre experience. You had elite talent in some spots and total chaos in others. It’s a weird paradox. You can have a "bend but don't break" philosophy, but eventually, if you bend too much, you’re just broken.
The Statistical Nightmare: Who Actually Stayed at the Bottom?
Numbers don't always tell the whole story, but they’re a pretty good place to start when your secondary is getting shredded like Swiss cheese. The Jacksonville Jaguars spent a huge chunk of the 2024 season statistically hovering near the basement. It wasn’t just that they gave up yards; it was how they gave them up. We're talking about massive chunks of real estate. When a quarterback knows he can drop back and find a guy open by five yards on every third-and-long, you’ve got a problem.
The Jaguars’ secondary struggled with communication. That’s the "silent killer" in the NFL. You’d see Tyson Campbell or Ronald Darby looking at each other after a touchdown like, "I thought you had the over route."
Then you have the Baltimore Ravens. This was the most shocking development of the year. For a team with Kyle Hamilton—arguably the most versatile safety in the league—the Ravens spent the first half of the season as the literal worst passing defense 2024 in terms of yards allowed per game. They were giving up nearly 300 yards through the air consistently. It felt like every week, a different random receiver was having a career day against them. Dak Prescott and Gardner Minshew both had field days. It was weirdly un-Ravens-like.
Why the "Good" Teams Ended Up with the "Bad" Stats
It’s easy to look at a list and say, "Oh, the Ravens sucked." But context matters.

Part of the reason Baltimore and even the Cincinnati Bengals found themselves in the conversation for the worst passing defense 2024 is because they were often leading. When you’re winning, teams stop running the ball. They start chucking it. If you’re playing the Kansas City Chiefs or the Buffalo Bills, your pass defense stats are going to take a hit because Patrick Mahomes isn't going to just hand the ball off 40 times if he’s trailing.
But let’s be real. Scheme played a massive role.
Zach Orr, taking over for Mike Macdonald in Baltimore, had some serious growing pains. The "simulated pressures" weren't getting home as fast. This left cornerbacks on an island for four or five seconds. Nobody in the NFL can cover for five seconds. Not Sauce Gardner, not Jalen Ramsey. Nobody.
The Disaster in Jacksonville
The Jaguars were a different story. Ryan Nielsen came in with a heavy press-man coverage scheme. It sounds great on paper. "We're going to get in their faces and be physical." In reality? If your corners aren't faster than the guys they're lining up against, you’re just asking to get beat deep. And they did. Repeatedly. They lacked the pass rush to complement the aggressive coverage, which is a recipe for a statistical funeral.
The Impact of the "Middle-Field Open" Trend
In 2024, offensive coordinators got really smart about attacking the seams. If you look at the teams that struggled the most, they often played a lot of "Cover 2" or "Quarters" but lacked the linebackers who could actually run with tight ends.
The Indianapolis Colts were another group that flirted with the worst passing defense 2024 title. Gus Bradley loves his Cover 3. Everyone knows he loves Cover 3. So, what did quarterbacks do? They hit the "seam" and the "flats" until the Colts were forced to adjust, which they rarely did. It’s frustrating for fans. You see the same 10-yard completion four times in a row, and the defense just keeps backing up.

- Communication Breakdowns: This is usually why you see a receiver standing by himself in the end zone.
- Lack of Pass Rush: If the QB has a clean pocket, your secondary is toast.
- Youth: Teams like the Arizona Cardinals played a lot of young guys who just didn't have the "NFL eyes" yet.
The Cardinals were actually interesting because they were "bad" but played hard. Their stats were inflated because their offense could actually score, leading to shootouts. But man, when they faced a veteran like Matthew Stafford, it was surgery. He just picked apart the zones because the young safeties weren't disguising their intentions.
The "Trash Man" Theory of Secondary Play
There’s this idea in football circles that your secondary is only as good as your worst player. You can have a lockdown corner on the left side, but if your nickel corner or your strong safety is a liability, the quarterback will just find them.
Every. Single. Time.
Look at the Dallas Cowboys. Losing DaRon Bland for a huge stretch changed everything. Suddenly, teams weren't afraid to look away from Trevon Diggs. They found the weakness. The Cowboys' passing defense stats plummeted because the depth just wasn't there. It shows how fragile a "good" defense really is.
Evaluating the "Worst" Label
Is it yards? Is it touchdowns? Is it Passer Rating allowed?
If you go by pure yardage, the 2024 Ravens were historically bad for a playoff-caliber team. If you go by "Expected Points Added" (EPA) per dropback, the Jaguars and the Panthers were often in a race for the bottom. The Panthers' defense was basically a revolving door. They traded away Brian Burns, their best pass rusher, and suddenly their secondary had to cover forever. You can't blame the DBs entirely when there is zero pressure on the ball.

The Bengals also had a rough go. Losing Chidobe Awuzie in previous years and trying to get younger with guys like DJ Turner II and Jordan Battle led to some "rookie moments" that cost them games. Joe Burrow would put up 30 points, and the defense would give up 31. That’s the definition of a nightmare season.
What We Learned from the 2024 Failures
The biggest takeaway from the worst passing defense 2024 data is that the NFL is moving toward a "positionless" passing attack.
If your safeties can't play nickel, and your nickel can't play outside, you're in trouble. The teams that got burnt the most were the ones that were too rigid. You can't just line up in the same spot every time. Quarterbacks like C.J. Stroud and Jordan Love are too good at pre-snap reads. They see the single-high safety and immediately know where the hole is.
How to Fix a Bottom-Tier Secondary
Fixing this isn't just about drafting a corner in the first round. It's often about the "marriage" between the rush and the cover.
- Simplify the Language: If players are thinking, they aren't playing. The mid-season turnaround for some of these units happened when coaches stopped trying to be "geniuses" and let their athletes just react.
- Invest in the Slot: The nickel corner is basically a starter now. Teams that treated it as a backup position got destroyed by guys like Amon-Ra St. Brown or Cooper Kupp.
- Disguise Everything: The best defenses in 2024 were the ones that made every play look the same until the ball was snapped. The worst ones were as predictable as a Hallmark movie.
Final Thoughts on the 2024 Air Show
Ultimately, being the worst passing defense 2024 is a badge of shame that usually leads to coaching changes. We saw it happen. We saw the defensive staff shuffling in places like Jacksonville. The margin for error in the modern NFL is so thin that a single missed assignment can be the difference between a playoff berth and a top-five draft pick.
If you're a fan of a team that couldn't stop a beach ball in the air this year, the silver lining is that secondary play is volatile. A new coordinator or one lockdown veteran in free agency can flip the script. But for the 2024 season, the tape doesn't lie. It was a long year for defensive backs.
Actionable Insights for Evaluating Defenses
- Look Beyond Yards: Check the "Yards Per Attempt" (YPA). A team might give up 300 yards, but if it took 60 passes to get there, they actually played well. If they give up 300 yards on 20 passes, fire everyone.
- Watch the Pass Rush Win Rate: If a team is in the bottom five of passing defense, check their sack count. Usually, the two are linked. A "bad" secondary is often just a secondary that has to cover for too long.
- Red Zone Success: Some teams give up a ton of yards but tighten up in the red zone. This "bend but don't break" style can be frustrating but effective. The truly "worst" defenses are the ones that give up the 40-yard bombs for scores.
- Track Personnel Groupings: Notice if a team struggles specifically against 11-personnel (3 receivers). This usually indicates a weakness at the nickel corner or a linebacker who can't cover a slot receiver.
