**Justin Herbert enters Week 5 of the 2026 NFL season with just 4 passing touchdowns against 6 interceptions through four games, posting an inefficient 70.6 passer rating on 816 yards.** The Chargers sit at 0-4, hampered by a decimated offensive line—left tackle Rashawn Slater is on injured reserve after ankle surgery, right tackle Joe Alt is out with a neck injury, and additional linemen are sidelined—leading to heavy pressure and sacks. Key skill-position injuries, including wide receivers Quentin Johnston and questions around Ladd McConkey, further limit downfield options in new offensive coordinator Mike McDaniel’s scheme. A favorable home matchup against Denver looms next, but the remaining schedule features difficult opponents, with the team’s Week 7 bye providing limited immediate relief. These factors shape trader views on Herbert’s full-season touchdown total amid ongoing roster challenges.
