Desert Deception: Inside the NFL's Most Unpredictable Defense
Armed with a rebuilt front and the versatile Budda Baker, Jonathan Gannon's unique system of hybrid fronts and college-style coverages is finally ready to dominate.
The scheme for the Cardinals is unique to them. Jonathan Gannon transitioned to a Fangio-adjacent system when he took over as the Eagles’ defensive coordinator in 2021. One of his key departures from Fango himself was the use of Quarters instead of the Cover 6 (Stuff)/8 system preferred by Fangio.
Gannon worked for Mike Zimmer in Minnesota and then Matt Eberflus (Cowboys DC) in Indianapolis before moving to Philadelphia. Neither one of those coaches is seen as a split-field coach.
Zimmer is multiple, but static, and is known more for his double A-gap pressure package. Eberflus is a traditional 4-3 Cover 3/Tampa coach, again, nothing even close to resembling what the Cardinals are doing now.
The past two years have been defined by the high use of Quarters while utilizing a five-man front. In 2023, the Cardinals led the league in Quarters usage at just over 30%. The defense used the extreme talents of All-Pro Safety Budda Baker, moving him around and placing him in their three-high structure as the Middle Safety. Nickel Garrett Williams' hybrid ability allowed him to morph into a box overhang or deep Safety, depending on the call.
The lack of overall talent forced the defense to be relatively vanilla in every other aspect. In 2023, the Cardinals had one of the worst pressure percentages and were in the lower third in the league in pass blitz percentages. Though they were above league average in coverage disguise, the defense couldn’t stop anybody and finished dead last in DVOA.
With additions like hybrid off-ball linebacker Mack Wilson Sr. (Patriots) and the emergence of Max Melton at CB, the Cardinals’ defense rose to 14th in DVOA in ‘24. Statistically, the Cardinals were middle of the league in almost everything last season.
Schematically, the Cardinals were still using their unique three-safety alignment, but were adding more pressure and more disguises. 2024 saw the Cardinals jump to seventh in Blitz Rate (31.8%) and fourth in coverage disguise. The defense was becoming more complex, but still lacked a solid front that could consistently hold up against the run.
Although Arizona was top ten in sacks (41), their Pass Rush Production was 24th overall (according to PFF). It’s not surprising the front office leaned heavily into rebuilding the entire front. The current trend in the NFL is to build from the front, adding premium talent on the line of scrimmage to enhance the coverage ability (or lack thereof) of the secondary.

Minny may match it though. I am holding out hope. The names for DC continue to get better. Maybe we can work out way up to Schwartz or Ulbrich. Wishful thinking but hey!
