It has been over a year since Jonathan Gannon and the Arizona Cardinals parted ways, and on Monday, the former head coach broke his silence. In a candid media session, Gannon reflected on what he described as an "unforgettable chapter" in his coaching career.
This interview, first reported by Burn City Sports, comes as the Cardinals enter their second season under head coach Mike LaFleur, who succeeded Gannon after the 2024 campaign. With a new coaching staff, a refreshed roster, and renewed energy, Gannon's perspective provides a unique insight into a challenging era marked by high expectations, struggles, and eventual transition.
Candid Reflections on a Challenging Tenure
Hired in February 2023 following a successful run as the defensive coordinator for the Philadelphia Eagles, Gannon spoke with a tone blending gratitude and realism. He acknowledged difficulties faced during his time in Arizona and that the on-field outcomes fell short of the aspirations he held upon arrival.
"Playing and coaching in the NFL, you learn that every stop leaves a mark on you," Gannon said, per Burn City Sports. "Arizona was no different. I'm grateful for the opportunity Mr. Bidwill and Monti [Ossenfort] gave me. We had a plan, worked hard to execute it, and though it didn't end as any of us wanted, I wouldn't trade the experience for anything."
Gannon arrived amid a transitional phase. The franchise was moving on from former head coach Kliff Kingsbury, had traded legendary wide receiver DeAndre Hopkins, and was navigating quarterback Kyler Murray's recovery from a torn ACL that sidelined him for most of the 2022 season. This period marked the beginning of a rebuild, with Gannon tasked as architect.
The 2023 season, his first as head coach, was a struggle. The Cardinals posted a 4-13 record, but flashes of promise existed. Despite the losing record, the team showed competitive spirit, and the defense, though statistically below average, exhibited glimpses of the aggressive, opportunistic style Gannon instilled in Philadelphia. The season was largely viewed as a strategic low point to secure a high draft pick, which paid off with the selection of Marvin Harrison Jr. fourth overall in the 2024 NFL Draft.
The 2024 Season and Its Impact
The following 2024 season brought heightened expectations. Murray was fully recovered, Harrison Jr. bolstered the receiving corps, and defensive additions like cornerback Will Johnson (drafted) and linebacker Josh Sweat (free agency) promised improvement. The team started strong at 6-4, igniting playoff hopes among fans.
However, a late-season collapse, losing five of the final seven games, ended the campaign with an 8-9 record. Progress was evident but insufficient. Questions about Gannon's leadership arose due to the defensive lapses and inconsistent finishes.
Gannon on His Departure
On the conclusion of his tenure, Gannon was measured and honest. He acknowledged the frustrations while defending the foundational work accomplished.
"I feel like we built a foundation," he said. "We brought in the right kind of guys -- players who loved the game, who were selfless, who wanted to be part of something special. Players like Trey McBride, Budda Baker, Paris Johnson Jr. -- those are pillars of a winning program. I'm proud of the culture we established."
Indeed, many of these players remain central to the Cardinals' roster. McBride has developed into a premier tight end, Baker continues as a key defensive leader, and Johnson Jr. has solidified the left tackle spot. Linebacker Zaven Collins transitioned under Gannon to an effective edge rusher role, illustrating the adaptability within the roster constructed during Gannon's era.
Yet, the defense struggled to meet expectations. Despite investments including players like Darius Robinson, Walter Nolen III, and Josh Sweat, Arizona finished 2024 ranked 20th in total defense and 22nd in points allowed. For a coach known as a defensive expert -- coming off the Eagles' top-ranked 2022 defense -- these outcomes fell short.
"I was disappointed we couldn't get the defense to where it needed to be," Gannon admitted. "Defense is my identity. Those struggles were personal. I had many sleepless nights trying to unlock that group. But I still believe the talent is there."
Transition to the LaFleur Era
Gannon's reflections arrive as the Cardinals thrive under Mike LaFleur, who became head coach in 2025. With an offensive background, LaFleur and offensive coordinator Nathaniel Hackett have reinvigorated the team's offensive identity, shifting from Gannon's defensive focus.
In LaFleur's inaugural season, the Cardinals improved to 10-7 and made the playoffs for the first time since 2021. They secured a Wild Card victory over the Dallas Cowboys before bowing out to the San Francisco 49ers in the Divisional Round. Marvin Harrison Jr. emerged as a star with 1,200 receiving yards and 10 touchdowns. The running game, led by James Conner and rookie Jeremiyah Love, ranked among the league's best.
The defensive turnaround under coordinator Nick Rallis -- a holdover from Gannon's staff -- has been remarkable. The Cardinals finished sixth in total defense and fifth in scoring defense in 2025, fueled by a potent pass rush from Josh Sweat and the re-energized BJ Ojulari. The secondary, featuring Will Johnson, Sean Murphy-Bunting, and Garrett Williams, showcased significantly improved coverage.
Gannon expressed pride in this progress despite no longer being with the team.
"I see what Nick and the guys are doing, and I'm happy for them," Gannon said. "I know many of those players and how hard they work. It's great to see them get the recognition they deserve. Sometimes it just takes longer to click. I'm glad they're clicking now."
Looking Ahead for Jonathan Gannon
At 40 years old, Gannon remains a highly regarded defensive mind. Before his head coaching stint, he was one of the league's brightest coordinators. He has begun receiving inquiries from teams interested in bolstering their defensive staffs.
"I'm in no rush," Gannon emphasized. "I want the right fit. Arizona taught me a lot--about leadership, about what it takes to win consistently. I know I'm a better coach now. I'm excited for the next chapter, wherever that may be."
Speculation suggests potential returns to defensive coordinator roles from teams like the Miami Dolphins, Las Vegas Raiders, and New Orleans Saints. Rumors of a second head coaching opportunity exist but appear unlikely in the near term.
Gannon's Legacy in Arizona
For Cardinals fans, Gannon's tenure remains mixed. The 4-13 season, late collapses, and defensive struggles are tough to forget. Yet, the foundation he helped establish underpins the recent progress. His drafting of key contributors, cultural emphasis, and professionalism during adversity laid groundwork for the current success.
He may be best remembered as a bridge between the difficult post-Kingsbury era and the promising LaFleur-led future. Although he did not see the rebuild through to its fruition, his imprint endures.
"I'm grateful to the Bidwill family, the players, and the fans," Gannon said. "Arizona and the Valley are special places. I gave it everything I had -- that's all you can do in this league. You give your all, learn, and get better. That's what I did. And now, I'm ready for what's next."
The Road Ahead for the Cardinals
The 2026 Cardinals aim higher than before, powered by a loaded roster, a strong coaching staff, and an energized fanbase ready to chase a Super Bowl. While Gannon is no longer at the helm, his contributions remain a critical part of the franchise's upward trajectory.
On this Monday afternoon, as the team prepares for the coming season, it's fitting to pause and hear from the man who helped rebuild the engine--even if he did not drive it to the finish line himself.
