When the Arizona Cardinals hired Jonathan Gannon as head coach and Nick Rallis as defensive coordinator, the assumption was that we would see a shift from the 3-4 base defensive scheme the team has used basically every year since 2007, excluding 2018 with Steve Wilks as head coach, to a 4-3 base scheme.
After all, Gannon’s defense in Philadelphia was, on paper, a 4-3 scheme, and the defenses he worked with as an assistant in Indianapolis and Minnesota were 4-3 schemes as well.
