The Chargers have hired James Campen as the offensive line coach for at least the 2020 season (per Rob Demovsky, ESPN). Along with Campen, the team is also bringing in David Diaz-Infante as an assistant offensive line coach (per Field Yates, ESPN).
The Chargers seem to be looking to lock down their coaching staff rather quickly for the upcoming season. The team recently extended head coach Anthony Lynn as well as officially deciding to make Shane Steichen the full-time offensive coordinator and keeping Gus Bradley in control of the defense.
