Gannon was hired by the Cardinals following the Eagles’ Super Bowl run after the 2022 season, leaving Philadelphia just days after the loss to Kansas City.

The timing mattered. Because Arizona moved so late, the Eagles lost their chance to hire Vic Fangio that offseason, scrambled to fill the role, and ended up with Sean Desai for 2023 before finally landing Fangio in 2024.

That move, of course, worked out just fine for Philly, ending with a Super Bowl parade.

Arizona, meanwhile, never got off the ground.

The Cardinals showed brief life early in the 2024 season, winning their first two games, then completely collapsed. They managed just one win the rest of the way and closed the year on a nine-game losing streak.

That kind of finish makes ownership decisions pretty easy.

Gannon originally came to Philadelphia with Nick Sirianni from Indianapolis in 2021 and spent two seasons as the Eagles’ defensive coordinator. His final game in that role was Super Bowl LVII, a night Eagles fans still remember for all the wrong reasons.

Jonathan Gannon’s exit from Philly also came with baggage. In early 2023, the league determined that Cardinals GM Monti Ossenfort had illegal contact with Gannon following the NFC Championship Game. The situation was settled with a draft pick swap that sent Arizona’s third-round pick to the Eagles, a quiet but meaningful win for Philadelphia.

When Jonathan Gannon took the Arizona job, he brought former Eagles linebackers coach Nick Rallis with him and later reunited with Josh Sweat in free agency. Sweat signed a massive deal and still produced, logging 12 sacks in 2025, but individual stats were never enough to mask a team that simply did not improve.

Three years, three losing seasons, and no clear direction later, the Cardinals are starting over again. Eagles fans, meanwhile, can look back at the entire saga and feel pretty good about how it all turned out.
