Why Chargers are confident Justin Herbert will be able to ‘attack down the field more’

Looking for answers on the offensive line, Zion Johnson and returning starting center Bradley Bozeman alternated days at center and left guard during offseason sessions. When left tackle Rashawn Slater joined the team for minicamp, the potential starting offensive line looked significantly different than the one that got steamrolled in the playoffs.

While Bozeman and Johnson continue to jockey at center and left guard, key free-agent signing Mekhi Becton has solidified the right guard position. The 6-foot-7 Super Bowl champion and 6-foot-8 tackle Joe Alt have the potential to be a dominant right-side duo.

Coaches mentioned Jamaree Salyer as someone who could still battle for a major role on the inside with Bozeman and Johnson, along with free-agent addition Andre James, who was a starting center for three seasons with the Las Vegas Raiders. After starting last season as the team’s No. 1 right guard, Trey Pipkins III’s role remains unclear.

Considering both a player’s contribution at an individual position and how well a specific combination works together, Harbaugh said he hopes to set the starting lineup around eight to 10 days into training camp.

“It’s always who’s playing the best [and] best combination,” Harbaugh said. “How do we know that? They play the best. It’s really that simple.”
