Jim Harbaugh is once again considering a familiar face for his defensive coordinator vacancy. The Chargers announced this evening that they’ve interviewed Chris O’Leary for the role.
Unlike some of the other familiar candidates for the job, O’Leary wasn’t on the Chargers staff in 2025. Rather, he was on Harbaugh’s inaugural staff in Los Angeles, where the assistant served as the Chargers safeties coach. During that 2024 campaign, O’Leary guided a safeties group that led the NFL in sacks (6.5) and finished fifth in interceptions (nine). As Omar Navarro of the team’s website notes, the Chargers safeties also allowed a 75.9 passer rating when targeted, which was good for third at the position in the NFL.
He left to become the defensive coordinator at Western Michigan in 2025. During his one season at the school, O’Leary led a defense that ranked second in the Mid-American Conference in total defense (17.4 points per game). That mark also ranked ninth in all of FBS.
Other than his one-season stint on the Chargers coaching staff, all of O’Leary’s coaching experience has come in the college game. He got his first gig at Georgia State before being named the safeties coach at Florida Tech in 2017. After one year in that role, he left for Notre Dame, where he ended up spending six seasons. During his time with the Fighting Irish, O’Leary worked his way up from a defensive analyst to defensive backs coach.
Since Jesse Minter left to become the Ravens head coach, Harbaugh has considered a handful of internal candidates for the DC job. That includes safeties coach Adam Fuller, who replaced O’Leary in the role this past season. The full list of candidates includes:
- Steve Clinkscale, defensive backs coach (Chargers): Interviewed 1/26
- Adam Fuller, safeties coach (Chargers): Interviewed 1/26
- Jim Leonhard, defensive backs coach (Broncos): Interviewed 1/28
