Fuller arrives in the wake of Chargers safeties coach Chris O’Leary going to take the defensive coordinator role at Western Michigan. He spent 2020-2024 with the Seminoles and has had prior stops at the college level at places such as Memphis and Marshall.

The hire aligns with Harbaugh’s vision for a more physical and adaptable defense in 2025. With Fuller’s extensive knowledge of the defensive side of the ball, the Chargers are hoping he can take their defense to the next level as he has done many times before.

After a very successful first year with the Los Angeles Chargers that saw the team make the playoffs, head coach Jim Harbaugh is retooling for next season and is adding some fresh faces to his staff.

According to Pete Thamel of ESPN, Chargers safeties coach Chris O’Leary will leave the Chargers to take up the mantle as defensive coordinator at Western Michigan. The Athletic’s Daniel Popper put it best in response to the news, citing O’Leary as a “big loss” for the Chargers.
