The Packers hired Jonathan Gannon as defensive coordinator in 2023, but the defense underperformed, failing to meet expectations despite his reputation.

In an effort to revitalize a faltering defense, the Green Bay Packers appointed Jonathan Gannon as defensive coordinator in 2023. Although Gannon, who had previously played for the Arizona Cardinals and Philadelphia Eagles, was known for his strong defensive play, the Packers' defense struggled in 2023 and finished close to the bottom in important metrics. Fans had differing opinions about his hiring, particularly in light of his part in the Eagles' Super Bowl victory over Green Bay. The team is still confident in his abilities despite the criticism, but there are still concerns about how he will affect the defense and long-term success.
