Chargers at 22: guard upgrade, tackle insurance, and Johnston's value

With the draft near, the Chargers’ No. 22 pick would likely be used to address left guard rather than lock in a pure tackle, unless the prospect can move inside to guard for McDaniel’s outside-zone scheme. Slater and Alt are expected to return, so the focus is depth at guard and tackle insurance; potential guard targets include Olaivavega Ioane, Chase Bisontis, Emmanuel Pregnon, Keylan Rutledge and Gennings Dunker. Trading Johnston for Day-3 picks doesn’t make sense given his cheap contract and upside, though the team will weigh the fifth-year option before May 1. If they don’t add an edge rusher in the draft, post-draft veteran options (Clowney, Jordan, Floyd, Miller) could surface as targets.
