Jonathan Gannon’s vision for the Packers defense goes well beyond a simple scheme change
Packers’ defense is set to look drastically different under Jonathan Gannon’s creative disguise-heavy scheme, and it won’t be what he ran for the Eagles or Cardinals.
The Green Bay Packers’ defense will undergo a significant schematic transformation in 2026, and the early signs from training camp suggest Jonathan Gannon’s system will feature an unpredictable, disguise-heavy approach unlike anything the coach himself has deployed in recent years.
Green Bay hired Gannon as its new defensive coordinator after Jeff Hafley left to become the Miami Dolphins head coach, and the shift represents a philosophical pivot from the single-high Cover 3 principles Hafley brought from the Robert Saleh and San Francisco 49ers coaching tree. Gannon’s system will instead operate primarily out of two-high shells, with layers of deception designed to confuse opposing quarterbacks after the snap.
Gannon’s scheme won’t mirror Philadelphia or Arizona
The fascinating element of this transition is that Gannon’s Packers defense won’t simply replicate what he ran elsewhere. Gannon has been the primary defensive mind in two stints during his career. He served as defensive coordinator for the Philadelphia Eagles for two seasons before becoming head coach of the Arizona Cardinals for three years.
In Arizona, though, defensive coordinator Nick Rallis handled play-calling duties. That Cardinals’ defense was creative in its structures, disguises, and back-end coverage designs, but Gannon wasn’t the one making calls on game day, even though he was involved in game planning and building the defensive framework.
The Packers won’t have the same players or the same styles of players Arizona had, and the defense will inevitably look different because Gannon will now be calling plays himself. That’s an inherent difference worth tracking throughout camp and into the season.
There was an expectation that Green Bay would run something more similar to what Gannon ran when he was the DC in Philadelphia. But LaFleur said Gannon will run a different style of defense. Packers defensive tackle Javon Hargrave, who played under Gannon with the Eagles, confirmed the system and scheme are a lot different than what they ran in Philadelphia.
LaFleur impressed by defensive disguises in early practices
Matt LaFleur said when analyzing the defense after the first couple of training camp practices that the disguises caught his attention because they are so extreme and difficult to parse.
“I think there was a lot of learning that transpired over the course of the offseason,” LaFleur explained. “JG does such a great job of giving you some of those disguises. You can’t tell, are they coming or are they not coming. That’s only going to get amplified the further we move into training camp. Obviously, on Day 1, you’ve got a very limited menu. That’ll pick up today as we transition, and as we transition into some of those pass situations, some of those looks can get pretty exotic.”
Gannon is a creative play-designer and play-caller, and when Green Bay hired him, that ability to embrace unpredictability was one of his calling cards.
A return to disguises with a completely different approach
The Packers actually leaned heavily into disguises and creative schemes back in 2024. Hafley then backed off that approach and became more conservative last year, perhaps because the team had acquired edge defender Micah Parsons and those disguises presumably wouldn’t be as necessary. Still, they would have been helpful in making things easier for everyone else on the defense, including Parsons.
Now, Green Bay is returning to that world of pre-snap deception, but with a completely different foundational approach. And one that’s distinct from anything Gannon has shown at his previous stops. The Packers are blending his two-high principles with an aggressive disguise package that neither his Eagles nor his Cardinals defenses fully showcased.
There is a lot to learn about what this defense will look like once the scheme expands through training camp and into the regular season. The early returns suggest Green Bay is investing in complexity and unpredictability as core tenets of its 2026 defensive identity.
