The Arizona Cardinals’ defense has experienced a notable transformation in recent years, emerging as one of the most improved units in the NFL. For several seasons, the Cardinals struggled defensively, often finding themselves among the league’s worst in key categories like points allowed, passing yards allowed, and rushing defense. However, under head coach Jonathan Gannon and defensive coordinator Nick Rallis, the team has undergone a significant shift in philosophy and execution. With a blend of strategic acquisitions, improved player development, and a more disciplined approach, the Cardinals’ defense has taken a significant leap forward.
In 2023, the Cardinals ranked near the bottom of the NFL in most defensive categories. They allowed an alarming number of points per game and gave up significant yardage on the ground and through the air. This struggle was a continuation of the team’s defensive woes over the past several seasons. It was clear that the organization needed to make drastic changes to its defensive strategy, personnel, and overall mindset.
The offseason that followed proved to be a turning point for the franchise. One of the most important changes came in the form of leadership. Gannon, who had previously served as the defensive coordinator for the Philadelphia Eagles, brought a fresh perspective to the Cardinals. His aggressive, attacking style was a departure from the more passive approach that had defined the team’s defense in previous years. Gannon’s scheme was designed to make the defense more unpredictable, employing a variety of blitzes, stunts, and zone coverage concepts to confuse opposing offenses. His ability to adapt to different styles of play and emphasize situational football paid immediate dividends.
Beyond coaching changes, the Cardinals made key acquisitions in free agency and the draft to bolster their defense. The addition of veteran players with experience in a variety of systems was crucial. They brought in strong pass rushers and defensive backs to fill gaps left by departing players and help develop the team’s younger talent. Players like pass rusher Josh Sweat and linebacker Akeem Davis-Gaither became key pieces in the defensive puzzle, adding speed, toughness, and versatility to the unit.
Perhaps the most significant change was the way the Cardinals approached their defensive line. The team had long struggled to generate consistent pressure on opposing quarterbacks, leaving their secondary vulnerable to big plays. In 2024, however, the team invested heavily in improving their pass rush. The Cardinals brought in more physicality upfront with the acquisition of defensive tackle Dalvin Tomlinson, who provided the defense with much-needed strength in the middle of the field. Additionally, the emergence of young players like Zayven Collins and Myjai Sanders gave the team a more dynamic pass-rushing duo. Their ability to pressure the quarterback helped the secondary by forcing quicker throws and limiting the effectiveness of opposing offenses.
Another area of improvement for the Cardinals was their run defense. In previous seasons, the team had been gashed on the ground, struggling to stop ball carriers and often allowing long, sustaining drives that wore down the defense. This was especially true against teams with powerful running backs who could control the pace of the game. In 2024, the Cardinals’ defense became more stout against the run, thanks in part to the defensive line’s improvements and the linebacker corps playing with more discipline. The addition of Tomlinson and the development of players like Collins gave the defense the size and strength to clog running lanes and force opponents into passing situations.
Perhaps one of the most underrated aspects of the Cardinals’ defensive improvement was their secondary play. While the defense had previously been known for its vulnerability against explosive passing attacks, the 2024 season saw a resurgence in this area. Cornerbacks like Byron Murphy Jr. and Marco Wilson showed significant development, with the duo combining for several key interceptions and pass breakups. The Cardinals also strengthened their depth at safety, giving them more flexibility to rotate players and keep fresh legs on the field. This added depth allowed the team to match up better against high-powered passing offenses, which had been a major weakness in years past.
The transformation of the Cardinals’ defense was perhaps most evident in their performance against top-tier offenses. The team was able to disrupt some of the NFL’s most potent offenses, including the high-scoring Dallas Cowboys and Kansas City Chiefs. These victories highlighted the progress the Cardinals had made in becoming a legitimate defensive force. In particular, their ability to create turnovers and capitalize on mistakes was a key component of their success. This defensive opportunism allowed the team to stay competitive in games where their offense might not have been firing on all cylinders.
A big part of the Cardinals’ defensive improvement was the team’s commitment to creating a more aggressive, opportunistic mindset. Under Gannon’s leadership, the defense was not just content to play conservatively and prevent big plays. Instead, they actively sought to disrupt the opposing offense, taking calculated risks with blitzes and aggressive coverage schemes. This mentality led to more takeaways and forced turnovers, which in turn helped the offense get more opportunities to score. It also kept opposing quarterbacks on their toes, knowing that the Cardinals would be bringing pressure from different angles and trying to create chaos.
Additionally, the team’s defensive communication and cohesion significantly improved in 2024. The defense became more fluid and connected, with players working together to adjust on the fly and cover for each other’s mistakes. This was particularly important in high-pressure situations, such as third downs or the red zone. The team was able to hold strong and force offenses into difficult decisions, often leading to stalled drives and punts.
As the 2025 season approaches, the Cardinals’ defense is poised to continue its upward trajectory. With the continued development of key players and the leadership of Gannon and his staff, the team should be well-positioned to compete against some of the best offenses in the NFL. Additionally, the organization remains committed to further strengthening the defense, as seen by their continued focus on defensive acquisitions in the draft and free agency.
While there is still work to be done, the transformation of the Cardinals’ defense from a liability to one of the most improved units in the NFL is a testament to the hard work and dedication of the coaching staff, players, and front office. This defensive turnaround has the potential to make the Cardinals a serious contender in the NFC West and beyond. The team’s success will likely hinge on how well they can maintain their defensive improvements and continue to evolve their strategies to stay ahead of the competition.
In conclusion, the Arizona Cardinals’ defense has undergone one of the most impressive turnarounds in recent NFL history. What was once a struggling unit has now become one of the league’s most formidable defenses. Through smart acquisitions, coaching, and a more aggressive mindset, the team has built a defense that is capable of competing with the best. As the 2025 season unfolds, the Cardinals’ defense will remain a key factor in their pursuit of success and playoff contention.
