One of the biggest storylines surrounding the LA Chargers at the start of training camp is the ongoing offensive line debacle. After a year in which the interior offensive line really struggled, the Chargers' solution, outside of making one addition in Mekhi Becton, was to simply swap Zion Johnson and Bradley Bozeman.
Johnson struggled at left guard last season and has no NFL experience at center, but that is where he is getting reps in practice. Bozeman struggled at center and has historically been worse at left guard, yet that is where Harbaugh wants him.
Chargers fans are skeptical of this plan working out after seeing the same tandem struggle mightily last season.
