Chargers Backup QB Struggles Raise Questions Before Season

The Los Angeles Chargers' backup quarterback situation has become a concern after Trey Lance and DJ Uiagalelei struggled in preseason. Lance threw an interception and completed only 10 passes in Week 2, while Uiagalelei had 141 yards against third-stringers. The team may explore trades or waiver claims to find a more reliable option behind Justin Herbert.
The Chargers entered training camp expecting stability behind Justin Herbert, but preseason performances have undercut that confidence. Trey Lance, who impressed during last year's camp, has regressed, while DJ Uiagalelei's stats came almost entirely against third-string defenders. Neither has demonstrated the consistency needed for regular-season backup duty.
Head coach Jim Harbaugh has precedent for acting decisively in this situation, having traded for a backup just before Week 1 in a previous season. With final roster cuts approaching, the team could pursue a trade, scan waivers, or dip into free agency to find a veteran who better fits offensive coordinator Mike McDaniel's system.
This story may affect Chargers fans and fantasy football players who rely on Herbert's availability, as a weak backup increases the team's vulnerability to a season-altering collapse if the starter misses time. It could also influence how other NFL teams evaluate Lance and Uiagalelei on the waiver market. More broadly, it highlights how preseason depth-chart decisions can carry outsized consequences for a franchise's entire season, potentially shaping coaching staff job security and fan confidence before a single regular-season snap.
