Chris O’Leary: A Rising Star in NFL Coaching
The Los Angeles Chargers have made a significant move by appointing Chris O’Leary as their new defensive coordinator. O’Leary’s return to the Chargers is marked by a promising trajectory in his coaching career, showcasing a blend of experience and success that makes him a valuable asset to the team.
Previous Season as Safeties Coach
O’Leary joined the Chargers in 2024 as the safeties coach under Head Coach Jim Harbaugh. His first season with the team proved fruitful, with his unit emerging as the best in the NFL. The Chargers led the league in scoring defense, allowing an impressive average of just 17.7 points per game. This achievement laid a solid foundation for O’Leary’s promotion to defensive coordinator.
One standout player under O’Leary’s mentorship was safety Derwin James Jr. Not only did James secure his fourth Pro Bowl appearance, but he also earned recognition as a second-team All-Pro from the Associated Press. James’s exceptional year included a unique combination of statistics—70 tackles, five sacks, an interception, and five passes defended—highlighting the effectiveness of O’Leary’s coaching.
Success at Western Michigan
Before returning to the Chargers, O’Leary served as the defensive coordinator for Western Michigan in 2025. During his tenure, he transformed the Broncos’ defense, leading them to a commendable 10-4 record and securing the Mid-American Conference Championship. Under his direction, the defense ranked ninth in the FBS for scoring defense, allowing just 17.4 points per game, and showcased a strong overall performance, ranking 19th in total net yards allowed.
Such accomplishments not only underline O’Leary’s capacity to develop successful defensive strategies but also reflect his ability to motivate and uplift his players, turning a struggling unit into a powerhouse.
Contributions to Notre Dame
O’Leary’s impact in college football is equally impressive. Before his time at Western Michigan, he played a pivotal role in the Notre Dame defense during the 2023 season. The unit was recognized as one of the best in the nation, ranking fourth in passing yards allowed per game and second in red zone defense. Under his guidance, safety Xavier Watts made headlines by leading the nation with seven interceptions, earning All-American honors and the prestigious Bronko Nagurski Trophy, awarded to the top defensive player in college football.
Notably, O’Leary’s coaching also contributed to the development of future NFL talents, helping players achieve personal milestones while elevating the overall performance of the team.
