Background

Gannon was the head coach of the Arizona Cardinals from 2022-2025, where the team went 3-14 in 2025 and struggled defensively. He now moves into the defensive coordinator role in Green Bay, potentially representing an opportunity to specialize back into his core expertise.

Scheme and Tendencies

Gannon's core philosophy is adaptability—he builds schemes around what his players can do rather than forcing a rigid system. He'll implement a split-safety/two-high shell and disguised pressures to prevent explosive plays. The scheme is built on the front four generating pressure, with a 3-4 base but heavy nickel and multiple fronts. Gannon doesn't use blitzing extensively; instead he relies on defensive line pressure and coverage windows to generate stops. He'll adapt Nick Parsons and edge rushers to play clean 3-4 OLB roles. Key personnel: Xavier McKinney, Javon Hargrave, Devonte Wyatt, and linebackers who can cover tight ends and play seams underneath. The scheme features creative alignments and safeties lining up 10-12 yards deep with occasional three-safety looks.

2026 Outlook

Gannon’s defense will emphasize swarming to the ball, out-hitting opponents, and creating turnovers through adaptable, disguised schemes rather than a predictable coverage system. He’ll feature a split-safety structure with extended safeties playing deep, occasionally using three-safety looks. The scheme limits blitzing and instead relies on front-four pressure—key targets include Micah Parsons (post-ACL), Lukas Van Ness, and Brenton Cox at edge/OLB. Linebackers must excel in coverage, particularly against tight ends; Zaire Franklin and Edgerrin Cooper fit the profile despite Franklin’s 2025 struggles. The secondary will play with patience and discipline, featuring Xavier McKinney and coverage-versatile safeties. Gannon’s defense is built for takeaways and efficiency rather than pure pressure, making it a patient scheme that may limit splash plays but creates consistent disruption.
