The Green Bay Packers made a defensive shift when they hired Jonathan Gannon as defensive coordinator. Replacing Jeff Hafley, who left to become head coach of the Miami Dolphins, Gannon brings a résumé rooted in zone, disguise, and front four efficiency.
During his time as the Philadelphia Eagles’ defensive coordinator, Gannon built one of the NFL’s most consistent defenses by using split-safety coverages, match-zone, and a pass rush that won without heavy blitz usage. That will become the new norm for the Packers’ defense in 2026, and several defenders appear suited for this new system.
Safeties
Gannon’s defense relies heavily on quarters-style coverage, like Cover 4. Safeties are expected to cover deep zones, rotate after the snap, and help underneath when needed.
Xavier McKinney is expected to have a bigger role, moving between deep coverage, box support, and “robber” positions to disrupt passes. Evan Williams may also benefit, helping the defense stay disguised and confuse quarterbacks.
Linebackers
Gannon’s linebackers must cover. They are regularly asked to cover tight ends, carry seams, and close throwing windows in underneath zones.
Edgerrin Cooper fits extremely well in this environment. His speed and range allow him to play as an eraser in this structure, giving Green Bay flexibility to stay in two-high shells without sacrificing the middle-of-the-field.
If Quay Walker returns, he could be used with simulated pressure roles. If not, Gannon’s history suggests Green Bay will prioritize rangy coverage-capable linebackers going forward.
Edge Players
Another hallmark of Gannon’s system is simulated pressure. Edge defenders occasionally drop into coverage while linebackers or safeties rush, creating pressure without tipping it pre-snap.
Lukas Van Ness could benefit greatly from this defense. His size and athleticism enable him to be a stand-up edge, wide rusher, or flat dropper, expanding his overall impact beyond sack totals.
Interior Line
Gannon’s Eagles’ defense was powered by interior pressure. The ability to collapse pockets with four rushers is essential to making split-safety coverage work.
Devonte Wyatt’s first-step and penetration ability align well with this defense. Expect him to be featured in attacking one-gap roles, tasked with stressing guards and centers rather than absorbing double teams.
The Big Picture
Although blitzing may not be frequent, Gannon’s defense is designed to limit big plays, force long drives, and generate turnovers through positioning and disguise. If executed effectively, Gannon’s system could transform a talented but inconsistent defense into a stable and difficult unit to solve.
