Bozeman

Zion Johnson could move from left guard to center, which would put returning center Bradley Bozeman, right guard Trey Pipkins III and free-agent acquisition Andre James in line to compete for the left guard position.

His addition will add some competition, especially at left guard, where the options could be incumbent starter Zion Johnson, returning center Bradley Bozeman, former right guard Trey Pipkins III or free agent signing Andre James.

By re-signing returning center Bradley Bozeman, Hortiz hopes to have a competitive offseason to strengthen an offensive line that gave up four sacks in a playoff loss to the Houston Texans.

All three Chargers offensive linemen slated for free agency are centers, led by starter Bradley Bozeman.

Center Bradley Bozeman is a free agent after starting all 18 games in his first year with the Chargers.
