Matt LaFleur reveals how Packers defense can advance under Jonathan Gannon

Green Bay Packers defensive coordinator Jonathan Gannon may not appear to be an upgrade over his predecessor, but head coach Matt LaFleur insists last year's issues extended beyond who was in charge of the call sheet.

LaFleur has had a lot to say of late at the annual NFL meetings. While his stated intentions to keep Jordan Love's development humming were compelling, his comments on the plan for progress on defense proved juicy as well.

Based on LaFleur's vision for the unit and what Gannon brings to the table from a schematic standpoint, it feels like a match made in football heaven.

This is indeed an ideal opportunity for Gannon to redeem a stint as Arizona's head coach that fizzled out. In the long run, he may very well prove to be a superior fit to Jeff Hafley.

How Packers' quest for clarity aligns perfectly with new defensive coordinator Jonathan Gannon

Official team senior writer Wes Hodkiewicz broke down some key takeaways from the annual NFL meeting, which featured a whole section on Gannon. As one could imagine, LaFleur was effusive in his praise of his new defensive play-caller:

"I thought it was pretty clear when he came in there, man, the guy knows football...He's got a passion for football. He's done it at a high level. Obviously, what he did in Philly was pretty remarkable, getting them to the Super Bowl and I just love the experience that he has as not only a play-caller but as a head coach as well, somebody that I'll be able to bounce things off of from time to time."

But it was actually the section before, where LaFleur discussed some of what derailed the 2025 team and the root causes of frequent blown leads. Turns out, there were some disgruntled defenders whose frustrations might've triggered some of the late-game breakdowns.

"If I'm being honest about it, I think there were some guys that were upset about roles last year, and I think that took a toll on our football team. You need guys that bring great energy every day. I think from a coaching standpoint, role clarity is key. So, we've got to obviously do a better job communicating with our players, 'Hey here's your role and if you're unhappy about your role, it's on you to do something about that, to carve out a role on this football team.'"

Cultivating a closer team environment was a general theme across all of LaFleur's remarks. The key here is how the Packers' personnel on defense marries well with how Gannon should deploy them in his scheme.

First off, the veteran additions of defensive tackle Javon Hargrave and linebacker Zaire Franklin should go a long way in bringing that "great energy" LaFleur alluded to. Plenty of experience between those two.

Hargrave played under Gannon in Philly. Not only is he an exotic pass-rushing threat, but he's more cut out to play nose tackle than anyone the Cheeseheads deployed in 2025. His presence in tandem with a hopefully healthy Devonte Wyatt should have a trickle-down effect that keeps the rest of the interior rotation fresh.

Franklin fills the void left by Quay Walker, who priced himself out of Green Bay and was always chasing the unmet potential implied by his first-round draft status. Although he's coming off something of a down season, Franklin was a second-team All-Pro selection in 2024. He'll vie for snaps with Isaiah McDuffie in two-backer sets, raise the floor in base 4-3 alignments, and serve as a good veteran mentor for ascending youngster Edgerrin Cooper.

So as far as clarity of roles, at least on paper, the Packers are moving in the right direction on that front with their splashiest acquisition in free agency, and with Franklin, whom they traded for.

Beyond those two obvious new pieces, though, Green Bay's personnel at safety is right in Gannon's wheelhouse.

Gannon loves to deploy three-safety looks as much as anyone. Per ZoneCoverage.com, he did so at a 30 percent clip last year, and put the Cardinals in Cover 4/Quarters coverage as much as any team during his three seasons in the desert.

By contrast, Hafley was more into running Cover 3 and leaned a lot on Cover 6 when his defense did rotate to two-high safety shells. Here are the splits through Week 17 from this past season:

• Cardinals — Cover 3: 27%; Cover 4: 25%; Cover 6: 7%
• Packers — Cover 3: 32%; Cover 4: 14%; Cover 6: 16%

Cover 6 is essentially Quarters on one half of the field, and Cover 2 on the other half. Whether it was the box safety or slot corner buzzing to the hook zone depending on Hafley's coverage disguise, that's just trying to do too much based on the strength of the Packers' roster.

Gannon can get as creative as he wants with Xavier McKinney, Evan Williams and Javon Bullard at the safety and/or nickel spots. In fact, it wouldn't be a shock to see Green Bay target another nickel/safety type rather early in the 2026 NFL Draft to add to the mix.

Bullard was the nickel last year for the most part, yet he had 230 snaps at either safety spot, per PFF. McKinney had 61 snaps in the slot. Williams did a little bit of everything, too.

Whether Gannon wants to split those snaps up even more amongst that trio, or put them in fuller-times roles at their respective primary positions, his greater penchant for Cover 4/Match Quarters is a better fit for all of them, as opposed to Hafley's heavy reliance on Cover 3.

Without getting too in the weeds scheme-wise, the two-high shell creates a murkier pre-snap picture, whereas the one-high shell, by nature, puts the box safety closer to the line of scrimmage. This caps the upside McKinney, Williams, and Bullard have as a collective in pass coverage.

The Packers only had seven interceptions last season. Takeaways tend to vary year-over-year, but surely, Gannon can find a way to manufacture more turnovers in 2026 if the general principles he had in Arizona carry over to Green Bay.
