Jonathan Gannon’s exit in Arizona closed a three-year chapter that never produced the results the Cardinals hoped for. As the organization turns the page, one of the franchise’s most respected former players offered a blunt assessment of why the tenure never worked.
Why Did Tyrann Mathieu Question Jonathan Gannon’s Leadership After Cardinals Exit?
Retired safety Tyrann Mathieu, a Super Bowl champion and one of the most recognizable players in Cardinals history, did not hold back while reacting to Gannon’s dismissal on his podcast “In the Bayou With Tyrann Mathieu.”
Speaking after Arizona announced the move, Mathieu framed the decision as something that should have been obvious much earlier.
“I’ve got to tell you, bro. It wouldn’t have taken me three seasons to figure it out,” Mathieu said. “That’s the life of a loser.”
Mathieu’s criticism centered on what he felt was missing from Gannon as a leader. From his perspective, watching Cardinals games and postgame press conferences revealed a coach who never seemed fully invested in maximizing the roster’s best players.
“Just from the perspective of figuring out how to use your best players,” Mathieu said. “When I watch Cardinals games I say to myself, ‘Man, they don’t know what to do with Budda Baker. They don’t know what to do with Marvin Harrison.’ And I think as a coach, you should lose sleep trying to draw up ways and scheme up ways to make those dudes look great.”
Mathieu, who spent five seasons in Arizona and built close ties with the fan base and media during his time there, also took issue with Gannon’s public demeanor. He recalled how Gannon handled press conferences and his interactions with reporters, including longtime Cardinals writer Josh Weinfuss.

“You got to have some passion, man. It’s got to mean something to you,” Mathieu said. “Just too many times in press conferences and stuff, he’s just nonchalant. He’s arguing with Josh Weinfuss. Josh is that dude in the room. When you’re doing well, he supports you. When you’re doing bad, he’s going to ask you a hard question. He still hasn’t figured that out. It’s hard to create fans under that sort of environment.”
Gannon exits Arizona with a 15-36 record over three seasons, a stretch that included constant roster turnover and limited progress in the standings.
This season, Arizona ranked 22nd in PFSN’s Offense Impact Metric and 29th in PFSN’s Defense Impact Metric, respectively. Despite the struggles, several current Cardinals players, including quarterback Kyler Murray, posted messages of support after the firing became official. Owner Michael Bidwill and general manager Monti Ossenfort also emphasized that Gannon helped build a culture inside the building, even if the results did not follow.
Mathieu acknowledged Gannon’s earlier success as Philadelphia’s defensive coordinator but suggested the head-coaching jump may have come too soon.
“I wish him well,” Mathieu said. “I thought he did a great job with the Eagles. Sometimes coaches aren’t ready for that sort of a step.”
