The Arizona Cardinals have yet to make the playoffs in two years with Jonathan Gannon as head coach but improved on their win total by four games in 2024. As they look to continue building in the right direction, the Cardinals enter a pivotal offseason with significant capital in free agency and the 2025 NFL D

With 19 players hitting unrestricted free agency, the Cardinals will have the fourth-most cap space in the league with $77.9 million to spare, per Over The Cap. While clearly still in rebuilding mode, the upcoming free agency window will be the most important of general manager Monti Ossenfort’s tenure.

As they continue to build around young stars Trey McBride and Marvin Harrison Jr. offensively, Ossenfort has the unenviable task of choosing the direction he wishes to take the team. Quarterback Kyler Murray continues to be involved in trade rumors, while three starting offensive linemen are projected to leave in free agency.

Roster needs aside, the abundance of expected departures creates a lot of holes in the team. In addition to the offensive line, nearly every key edge rusher will enter free agency. Arizona could be forced to overhaul nearly two full positional groups.

With the freedom Ossenfort will have in free agency, just a few of the right moves could instantly turn the Cardinals into playoff contenders. However, mismanaging the offseason would be equally as damaging.

The Cardinals desperately need pass-rushers, and Joey Bosa is the biggest name available. After nine seasons with the Los Angeles Chargers, Bosa was released one week ahead of NFL free agency. As big of a splash as his signing would make, his fit in Nick Rallis’ defense would not be what the team desires.

As one of the most injury-prone players in the league, Bosa has played just 30 games over the last three years. With 23 absences in that time, he has been on the field for just 57 percent of the Chargers’ games since 2022. For a player making over $20 million in annual salary, Los Angeles paid him nearly $30 million just to stand on the sidelines.

Even without his durability concerns, Bosa is simply not a fit in Rallis’ 4-3 defense. He thrives in a blitz-heavy, 3-4 scheme that allows him to utilize his speed as an outside linebacker, which is not a setup Rallis operates in. The Cardinals experienced the failed style fit with Baron Browning in 2024, who managed just two sacks on the year.

Bosa enters free agency at 29 but is still expected to sign a lucrative deal with his next team. Though diminished, his talent is still there in spurts. The Cardinals just cannot be the team to fall into the trap. If they were to sign him, it would take a significant portion of their cap space, effectively limiting them fo

With Browning, Dennis Gardeck, Jesse Luketa and L.J. Collier all hitting free agency, Arizona cannot end the offseason without adding pass-rushers to its roster. The answer just cannot be Bosa, as tempting as it might be.

Whether or not they keep Murray, the Cardinals need to add receivers to their pass-catching unit in the offseason. The dry unit offered little depth behind Harrison and McBride in 2024, with no other player recording over 550 receiving yards. Even with Harrison’s expected second-year leap, Arizona needs at least one
