I brought up a few candidates that are popular around the league and a few that the Chargers might have an inside track with when I wrote about this last week. Based on Jim Harbaugh’s track record, I think it’s more likely that he picks a guy that he has history with and someone that isn’t looking for a one-year mercenary run with the team as his play caller for the upcoming season. Hopefully, whoever that is knows a good offensive line coach.
