The Jaguars had to make changes to their coaching staff, particularly after parting ways with defensive coordinator Mike Caldwell and his team. The new staff under Caldwell’s replacement, former Falcons defensive coordinator Ryan Nielsen, has been finalized, along with some updates on the offensive side. 
On defense, we knew about the additions of defensive backs coach Kris Richard and inside linebackers coach Matt House, as well as the retention of assistant defensive line coach Rory Segrest, outside linebackers coach Bill Shuey, and defensive quality control coach Patrick Reilly. Originally, we reported that Cory Robinson would be the team’s cornerbacks coach, but the latest update clarifies that he will serve as a defensive assistant and cornerbacks coach.
Completing the new defensive staff, the team hired Jeremy Garrett as the new defensive line coach, Michael Gray as assistant secondary coach and defensive analyst, and Mario Jeberaeel as assistant outside linebackers coach. Garrett replaces Brentson Bucker, who was let go with Caldwell. Gray and Jeberaeel both followed Nielsen from Atlanta. Gray joined the Falcons last year as a football analyst, while Jeberaeel worked as a special projects: defense coach last season.
On offense, Jacksonville introduced running backs coach Jerry Mack and offensive quality control coach Jamel Mutunga, while also promoting former offensive quality control coach Greg Austin to assistant offensive line coach. Mack takes over from Bernie Parmalee, who joined the Panthers after his departure from Jacksonville. This is Mack’s first coaching job in the NFL after 20 years coaching at the college level. Austin steps into the role left by Todd Washington, who was also let go with Parmalee and Caldwell. Mutunga moves into the quality control position after working as an offensive assistant with the Panthers last year.
These changes pave the way for the 2024 season in Duval. Adjustments on offense and a new defensive coaching staff mark the early stages of Jacksonville’s offseason. It will be interesting to see if the new defensive staff can help the young Jaguars team progress in the upcoming league year.
