OXNARD, Calif. — The sounds are a little different this year around the Dallas Cowboys’ training camp facility. It’s not difficult to find the defensive meeting room during the day.

It’s usually the loudest.

First-time defensive coordinator Christian Parker is putting his stamp on his new group. The communication issues of a year ago are unlikely to be repeated this coming season.

While the constant talking pre-snap is noticeable during practice, the 34-year-old Parker has the group using that same intensity when they’re preparing off the field. And the decibel level sometimes gets so loud that it impacts what others are doing nearby.

“It felt like playing on the road,” Cowboys quarterback Dak Prescott said of a recent offensive meeting. “We were just trying to install our (offense) and it was loud and intense. That’s contagious. You feel that on that side of the ball. That unit is giving you that, you want to do the same on offense. Nothing but good things to say about that unit.”

Parker wants his players to be trained to talk the same whether it’s a game, practice or meeting.

“If we’re showing a play from practice, for example, if you’re a linebacker on the field, you’re making the front adjustment,” Parker explained. “If you’re an outside linebacker and you see that the Y is off, you’re saying something to your partner. If I’m a DB, I’m calling out the coverage communication. Motion happens. We’re alerting this, we’re passing off this. Once the play starts, what is that communication?

“We want the meeting room to sound the same as it does on the field. Your brain doesn’t know when you’re not taking a physical rep. It just knows that your brain is strained. So as many reps that we can get on task on that is possible, we want to try to take advantage of those in that space.”

Cowboys coach and offensive play caller Brian Schottenheimer has been working in the NFL for over 25 years. Parker’s way of teaching communication “jumps out” to him.

“It’s loud in a good way,” Schottenheimer said. “There’s a lot of communication. I love what he says and how he refers to it as it’s two parts, giving and receiving. You just can’t be blurting out a bunch of stuff that doesn’t matter and confusing people. You got to give it, you got to receive it.

“And then there’s the nonverbal part, which I think that’s the thing that has probably caught me the most. We all talk about communication, the importance of it, but the way the defensive staff talks about is there’s no audio on the practice film. So therefore the visual hand signals of things are critical because otherwise you can say, ‘Yeah, I said it.’ But if you don’t visually give the signal, then how do we know if you said it when the music’s playing stuff? I think it’s really, really cool how they preach that.”

Parker understands that someone walking by their meeting room might think something is wrong. He says that’s a good thing.

“I can’t just be aimlessly yelling and saying a bunch of things if I don’t know who I’m talking to,” he said, “what those words mean, how that changes things, when we can adjust something, when we can’t. … We still have more to go, but there’s a lot of encouraging things that are happening from a vocal standpoint.”

Parker is taking over a mess. The 2025 Cowboys were probably the worst defense in franchise history. Trading superstar pass rusher Micah Parsons a week before the season started obviously didn’t help. They’ve made moves to improve the defensive roster, and they’re likely not done.

It would not be surprising to see Dallas add another edge rusher or inside linebacker before Week 1. But it remains to be seen if those additions could be as impactful as trading for an elite pass rusher such as Maxx Crosby or potentially signing 37-year-old Von Miller, MVP of Super Bowl 50.

If the season started this weekend, the defensive starters would likely be Rashan Gary and Donovan Ezeiruaku at outside linebacker/edge rushers, Quinnen Williams and Kenny Clark as the interior defensive linemen, DeMarvion Overshown and Dee Winters at inside linebacker, DaRon Bland and Cobie Durant at outside cornerback, Caleb Downs at nickel cornerback and Jalen Thompson and Malik Hooker at safety.

Regardless of that being the starting group or potential future upgrades, Parker appears to be laying a quality foundation.

“I think the first thing is we want to be detailed in our work and our fundamentals and technique and obviously the mastery of the scheme,” he said Wednesday. “But there’s an element of violence and physicality that we want to play with that we will play with. So I think it’s just kind of tying all those things together in terms of knowing your job, knowing what the man next to you is doing, who you are connected to, are you on an island on that certain play? And then doing that with an attitude and the physicality required to play this game.”

It’s difficult to project how much improvement the defense will display this season. It has played well in training camp since full pads came on Monday. But last year’s defense had good days at camp, too.

We’ll get a much better idea Tuesday when the Cowboys travel roughly 40 miles east to the Los Angeles Rams’ practice facility for a joint practice. Rams quarterback Matthew Stafford, the reigning NFL MVP, didn’t even participate in the teams’ joint practice last year and the Rams still did whatever they wanted on offense.

Could Dallas Cowboys take the 2025 Seattle Seahawks path?

“I think it’s real important, especially as much experience as Coach (Sean) McVay has and Matthew Stafford at that position,” Parker said. “The pre-snap looks and the motions and the things they do formationally. They’ve been a very successful offense during his tenure there. So it’s going to be a good test for us of where we’re at and make sure our eyes are right and we’re playing with the right demeanor.”

Parker is expected to call the defense during that practice as he has been during all camp practices, from the sideline on a handheld radio. It’s still to be determined if he will call the defense this season from the sideline or from the coaching booth. Schottenheimer said Thursday that “in a perfect world, he’ll be down” on the sideline.

Parker isn’t one to heap significant praise on anything that’s happening in camp practices. Things appear to be moving in the right direction. But he knows the defense and his first year on the job will be judged by the results on Sunday.

His views on that seem to line up with his response to a recent question about whether there are players he thinks have a similar leadership style as he does.

“We’ll wait to answer that,” Parker said. “We haven’t been in the fire yet.”
 
I can't remember any that bad. We have had some bad defense, and maybe it's recency bias, but that was the worst defense on any NFL team I have ever witnessed.


You wouldn't be too far off.

Per Google:

"On a per-game basis, the 2025 Dallas Cowboys defense allowed 30.1 points per game (PPG), which ranks 14th worst in NFL history since the 1970 AFL-NFL merger.

The 2025 Cowboys are one of fewer than 20 teams in the modern era to ever surrender over 30 points per game across a full season. They sit directly behind the 2020 Minnesota Vikings (30.3 PPG) and ahead of the 1980 San Francisco 49ers (30.0 PPG).

Even when adjusting to a per-game metric, 2025 remains the undisputed worst defensive season in Dallas Cowboys history. It represents the only time the franchise has ever averaged over 30 points allowed per game, easily eclipsing the previous club record of 29.6 PPG set by the infamous 2020 defense under Mike Nolan."
 
It's splitting hairs, but I wonder how that compares adjusted for scoring inflation, though. The average might have gone up close to half a point in the last five years.

Anyway, seems like Garrett has some really bad ones also, though not to Eberfail levels.
 
I'll say this though, the Hall of Fame game the other day had a graphic that showed Carolina was ranked something like 30th in defense in 2024, but climbed to I think 15th in 2025.

Getting to about average from dumpster fire can be done.
 
The really bad thing about that defense was it gave up points constantly and got no turnovers, the 2020 defense at least got a decent amount of turnovers.

When you take that into account I think it might've been the worst in our history, definitely bottom 3-5.

Good question.

Per Google:

"When adjusting for modern scoring inflation using relative metrics like Scoring Index (comparing a team's points allowed to the league average that season), the 2025 Dallas Cowboys defense looks slightly less disastrous historically, but still ranks as one of the worst modern units ever assembled.

Because the 2025 league average spiked to 23.0 points per game (PPG)—one of the highest-scoring seasons in modern NFL history—the Cowboys' 30.1 PPG allowed means they surrendered roughly 1.31 times the league average.

When looking purely at raw PPG, the 2025 Cowboys look worse than some historical defenses simply because teams score much more today than they did in the 1970s or 1990s. When adjusted relative to their own season's average, the hierarchy shifts:

The 2025 Cowboys: Allowed 30.1 PPG against a 23.0 PPG average. Surrendering 1.31 times the league average drops them from 14th worst in raw PPG down to roughly the 25th worst era-adjusted defense since the merger.

Even when adjusting for a high-scoring league environment, the 2025 unit remains the worst defense in Dallas Cowboys franchise history, though it has some close company.

2025 Cowboys: Allowed 30.1 PPG vs. 23.0 league average (+7.1 PPG above average).

2020 Cowboys: Allowed 29.6 PPG vs. 24.8 league average (+4.8 PPG above average). Because 2020 was the highest-scoring season in NFL history, that defense actually looks slightly "better" when inflation is considered.

1961 Cowboys: Allowed 26.6 PPG vs. 22.0 league average (+4.6 PPG above average)."
 
I'll say this though, the Hall of Fame game the other day had a graphic that showed Carolina was ranked something like 30th in defense in 2024, but climbed to I think 15th in 2025.

Getting to about average from dumpster fire can be done.

If we're mostly healthy I'd be shocked if we were any worse than about 18th in the league, not great but definitely good enough to win 10-12 games.

And I could easily see them being around 12ish.

Oh, there's no doubt it can be fixed, but even in my drunken ambivalence it was pretty obvious just how bad that defense was.
 
Grok agrees with 2025:

"What was the worst defense in Dallas Cowboys history. Don't just go by stats or scoring. Take into account different eras of football."

The 2025 Dallas Cowboys defense is the strongest candidate for the worst in franchise history when adjusting for eras of football, personnel context, and advanced metrics—not just raw points or yards.

It allowed a franchise-record 511 points (30.1 per game, worst in the NFL that year and second only to the 1960 expansion team’s 30.8 PPG in team history), ranked near the bottom in yards, yards per play, third-down defense, red-zone efficiency, and passer rating allowed, and finished with one of the worst defensive DVOA marks in NFL history since the metric’s tracking began in the late 1970s (around 22.5%, fourth-worst overall).

Why era-adjusted context elevates 2025 over pure counting stats​

  • Scoring environments differ sharply. In 1960, league scoring hovered around 21–22 points per team per game; allowing 30.8 PPG made the expansion Cowboys last in a 13-team league and reflected a brand-new roster with no established talent under Tom Landry. Modern NFL rules (pass protection, defensive restrictions, emphasis on the passing game) inflate scoring, yet the 2025 unit still produced historically poor efficiency numbers relative to its peers.
  • DVOA and efficiency metrics (which adjust for situation, opponent, and play-by-play value) place the 2025 defense among the absolute worst measured units since 1978—worse than most other Cowboys low points and comparable to legendary disasters like the early-1980s Colts or Buccaneers. Raw yards or points alone underrate this because they ignore how poorly the unit performed on a per-play basis against contemporary competition.
  • Personnel and scheme failures compounded the issues. After trading Micah Parsons and losing other key pieces (e.g., DeMarcus Lawrence earlier), the group under Matt Eberflus ranked last or near-last in multiple categories despite an offense that ranked near the top of the league in scoring. This was not an expansion or total rebuild situation; it was a competitive roster that still collapsed defensively.

Other historically poor units and why they rank behind​

  • 1960 (0-11-1): Allowed 369 points (30.8 PPG) and was last in the league in points and yards. As an expansion team with a makeshift roster in a lower-scoring era, the struggles were expected and foundational rather than a collapse of a more established program. It remains the raw PPG high-water mark but is heavily discounted by context.
  • 2013 (Monte Kiffin’s Tampa-2 experiment): Worst yards allowed in franchise history (6,645 total / ~415 per game). It was porous and ranked near the bottom in points (27.0 PPG), but the team still went 8-8 with a strong offense. It was a scheme mismatch more than pure talent failure and does not rank as poorly on efficiency metrics as 2025.
  • 2020: Allowed 473 points (29.6 PPG) and was historically bad against the run. Injuries and coaching issues played roles; it was widely discussed at the time as a contender for worst ever but finished behind 2025 in total points and DVOA standing.
  • 1989 (1-15): Allowed 393 points in Jimmy Johnson’s first year amid a full roster teardown. Bad, but transitional and in a different era; total points and efficiency do not match the modern lows.
  • Other notables (2010, 2024, late-1980s Landry years, early expansion seasons): High points allowed or poor rankings, but none combine the volume, efficiency, DVOA extremity, and non-rebuild context of 2025 as clearly.
Raw points or yards favor the early expansion years or high-volume modern seasons, but those ignore scoring inflation, schedule strength, and play-value adjustments. When factoring in relative performance within the era, roster expectations, and advanced metrics, the 2025 defense stands out as the franchise’s nadir—a unit that failed spectacularly despite resources and an otherwise competent surrounding team.
 
Nail in the coffin from Google AI. I asked specifically about DVOA:

The 2025 Dallas Cowboys defense is statistically the worst in franchise history by DVOA. [1, 2, 3]
Led by defensive coordinator Matt Eberflus, the 2025 unit finished with a historically poor 22.5% defensive DVOA. (Note: In defensive DVOA, a higher positive percentage indicates a worse defense, as it measures efficiency allowed to the opposing offense). [1, 4, 5]

Historical Context​

According to data compiled by Aaron Schatz, the 2025 Cowboys didn't just set a franchise low—they put together one of the most inefficient defensive campaigns in NFL history: [4, 6]

  • 4th Worst Ever: It ranks as the 4th worst single-season defensive DVOA in NFL history since tracking began. [3, 4]
  • Historical Comparison: The unit statistically performed worse than other famously bad defenses, such as the winless 2008 Detroit Lions and the 2015 New Orleans Saints. [3]
  • Franchise Records Broken: Along with its poor efficiency metrics, the 2025 defense allowed a franchise-record 511 points, giving up 30 or more points in nine different games. [1, 7]
The historically bad defense stood in stark contrast to the team's offense, which ranked among the best in the league and managed to carry the team to a 7-9-1 record despite the defensive collapse. [8, 9]

If you would like to explore this further, let me know if you want to look at how specific position groups (like the run vs. pass defense) fell apart, or if you want to compare it to other bad Cowboys defenses like 2020 or 2013. [10, 11]

===============

How They Compare: A Deep Dive

2025 vs. 2020 (The Mike Nolan Disaster)
Until recently, the 2020 defense under Mike Nolan was widely considered the most embarrassing unit in modern Cowboys history. [1]
  • The 2020 Flaw: That team completely forgot how to stop the run, surrendering a miserable 158.8 rushing yards per game and giving up 30+ points in each of their first four games. [1, 2]
  • The 2025 Difference: While the 2020 defense was bad, the 2025 defense was a complete catastrophic failure in every metric. The 2020 defense at least forced 23 turnovers to mitigate some of the damage. The 2025 team suffered from a complete absence of a pass rush and failed to force takeaways, meaning opposing offenses easily sustained long, high-efficiency drives week after week. [1, 2, 3]

2025 vs. 2013 (The Monte Kiffin "Yards" Era)
The 2013 defense under Monte Kiffin is famous for giving up an astronomical amount of real estate, allowing a whopping 415.3 yards per game.
  • The 2013 Flaw: They couldn't get off the field, famously giving up 40 first downs in a single game to the New Orleans Saints.
  • The 2025 Difference: DVOA is adjusted for era and opponent strength, which reveals why 2025 was so much worse. The 2013 team played in a highly explosive offensive era and, despite giving up massive yardage, actually forced 28 turnovers (including 15 interceptions). They managed to tighten up in the red zone far better than the 2025 unit, which lacked the playmaking ability to bail themselves out. [1, 2, 3, 4, 5]

The Verdict
The 2013 and 2020 defenses were bad due to specific structural flaws (2013 couldn't prevent yards; 2020 couldn't stop the run). However, 2025 stands alone as the worst because it combined an historically awful pass defense with an inability to get sacks or force turnovers, breaking the 500-point ceiling for the first time in franchise history. [1, 2, 3, 5]

Worse than the Marinelli Lions :lol :doh

I feel like once a decade we have a defense about that bad.

I think we can be better than that even.

The Panthers appear to have changed out about 6 starters from year to year, I’m sure we are the same or more, and I think our replacements are higher upside or flat better.

It may feel that way, but the numbers don't bear that out.
 
It may feel that way, but the numbers don't bear that out.

I’d probably agree that 2025 was the worst but I think it’s up for debate. For example despite being worst in points allowed per game, they were only 4th worst in Cowboys history in yards allowed.

The key point is that it’s debatable, and it’s like 2013, 2020, and 2024 were all very close to as bad.
 
Yeah, even if 2025 wins the title as the worst, we shouldn't have to even be debating it against multiple seasons from the last 15 years.

It was worse than either 2020 or 2013, each of which was historically bad in some dimension
