Justin Herbert has thrown just four passing touchdowns through four games in the 2026 season, accompanied by six interceptions and a 59.7% completion rate as the Los Angeles Chargers sit at 0-4. The offense has faced significant challenges under new coordinator Mike McDaniel, including poor pass protection that ranks near the bottom of the league. Key contributors on the line, including left tackle Rashawn Slater (high ankle sprain) and right tackle Joe Alt (neck), have been sidelined, limiting Herbert’s time in the pocket and downfield opportunities. Herbert remains healthy with no injury designation ahead of Week 5 against Denver, but the combination of schematic adjustments, receiver injuries, and early inefficiency shapes trader views on his full-season touchdown total. Historical production from prior years provides context for potential rebounds if protection and timing improve.
