A Cowboys Perspective on Jonathan Gannon Offers Insight Into Packers’ Biggest Defensive Move of 2026

There will be plenty more to unpack in the coming days regarding the Green Bay Packers’ decision to hire Jonathan Gannon as their new defensive coordinator. By most accounts, it is the most significant move the organization will make during the 2026 offseason, and there are layers of schematic, cultural, and philosophical implications still to explore.

This piece exists for a different reason.

Shortly after the Dallas Cowboys hired Christian Parker as their own defensive coordinator, Nick Harris of the Fort Worth Star-Telegram—who covers the Cowboys and previously worked for DallasCowboys.com—offered insight on a podcast into why Dallas ultimately did not hire Gannon. That perspective is worth examining, not because it definitively evaluates Gannon’s quality, but because it sheds light on how different organizations weigh the same candidate.

Why Dallas’ View of Gannon Matters

There are several reasons a Cowboys-centric view of Gannon is relevant for Packers fans.

First, the two teams’ defensive coordinator searches overlapped almost entirely. Of the Packers’ three known external interviews, Dallas interviewed all three: Gannon, Parker, and Daronte Jones, the Minnesota Vikings’ pass game coordinator and defensive backs coach. The only reported external candidate Green Bay interviewed who Dallas did not was Al Harris, who had just finished a four-year stint with the Cowboys as their defensive backs coach.

Second, Dallas began its search earlier. The Cowboys fired Matt Eberflus on January 6. Green Bay’s vacancy did not open until January 19, when Jeff Hafley departed for the Miami Dolphins’ head-coaching job. That head start allowed Dallas to complete its process faster, ultimately hiring Parker on January 22—one day before Gannon even interviewed with the Packers.

Whether Dallas made the “right” decision is unknowable in January. But they undeniably had a broader and earlier view of the market.

Third—and perhaps most important—the Cowboys and Packers exist on opposite ends of the organizational transparency spectrum. Green Bay is famously tight-lipped. Dallas, under Jerry Jones, is anything but.

Jones regularly speaks candidly—sometimes recklessly—to the media. He has publicly criticized former players, accidentally misnamed Micah Parsons multiple times in press conferences, and has reportedly leaked the Cowboys’ draft board on four separate occasions. That level of openness would be unthinkable at 1265 Lombardi Avenue. The Cowboys’ beat culture is simply more porous, which makes Harris’ comments especially informative.

How the Cowboys Viewed Jonathan Gannon

According to Harris, Gannon was viewed very favorably at the outset of Dallas’ process.

“Jonathan Gannon was a top-two contender from the very jump,” Harris said. “He has a lot of supporters in Dallas—whether it be Brian Schottenheimer, Clayton Adams, or others who’ve worked with him.”

The hesitation, however, centered on one recurring question:

“He’s very smart. He understands defenses. He gets it. But can he connect with the players?”

That question, Harris explained, was never fully answered to Dallas’ satisfaction during the interview process. And that mattered—a lot—given what the Cowboys believed went wrong with Eberflus.

Dallas’ internal takeaway from the Eberflus tenure was not about scheme or preparation, but communication. They believed in his ideas. They believed in his structure. But they felt he could not effectively translate those ideas to players on a consistent, personal level.

As Harris framed it, Dallas ultimately feared that hiring Gannon would replicate the same problem.

“As it got further along, I think they realized it would feel very similar to hiring Matt Eberflus again—from that perspective.”

Is That Critique Fair?

It is worth pausing here to separate style from substance.

Gannon is not a microphone-dominant, Central Casting version of a defensive coordinator. He does not project the aggressive, macho persona some teams gravitate toward. If that matters to you, it matters. If it doesn’t, it shouldn’t.

Importantly, there is strong on-field evidence that Gannon can communicate effectively—at least within his defensive system.

As Daire Carragher of Pro Football Focus and Packer Report has noted, Gannon’s Arizona Cardinals defense recorded just 10 coverage busts last season, the third-fewest in the entire NFL. That number is particularly impressive given that Arizona ran a quarters-based coverage system, which typically demands more on-field communication, not less.

If players consistently execute complex coverage rules without blowing assignments, it is difficult to argue that communication is fundamentally broken.

That does not mean Dallas was wrong to value interpersonal connection. It simply means their concern appears stylistic rather than evidentiary.

Context That May Have Influenced Dallas’ Decision

There are two additional contextual factors worth considering.

First, Gannon coached under Eberflus with the Indianapolis Colts from 2018 to 2020. Dallas may have subconsciously—or consciously—projected its dissatisfaction with Eberflus onto his former protégé.

Second, Gannon did not call plays in Arizona. That responsibility fell to Nick Rallis, his defensive coordinator and longtime collaborator from Philadelphia. If Dallas believed that Arizona’s low coverage-bust numbers were more attributable to Rallis and the staff than to Gannon himself, that could explain the skepticism.

That raises an obvious question, though: if Dallas doubted Gannon’s operational control, why did they enter the process with him as a top-two candidate in the first place?

Why Christian Parker Ultimately Won

According to Harris, the answer is simple.

“Parker blew them out of the water” in his second interview.

Dallas hired Parker within 24 hours of that meeting.

Parker, notably, began his NFL coaching career with the Packers in 2019. That shared lineage makes it almost inevitable that Gannon and Parker will be compared—directly or indirectly—moving forward, particularly if their defenses diverge in performance.

The Packers’ Bet

Green Bay evaluated the same candidate pool and came to a different conclusion. That does not make Dallas wrong, and it does not make Green Bay right—at least not yet.

What it does illustrate is that the Packers are betting on structure, clarity, and execution over performative communication. They are betting that Gannon’s results—especially in limiting mental errors—matter more than whether he “sounds” like a defensive coordinator.

In a league where miscommunication destroys defenses faster than talent deficiencies, that is not an unreasonable wager.

Only time will determine whether it pays off.
