5. The offensive line
The offensive line has been banged up with injuries, so it is more complex than the line just being bad. However, the injuries on the offensive line have exposed the lack of quality depth behind the starters, which is a bit concerning.
Yes, the Chargers have been unlucky with injuries, but injuries happen every single season to every single football team. There are serious issues with the depth of this offensive line and it has been exposed thus far this season.
Sam Tevi has been a pleasant surprise for the Bolts. While I would not go as far as to say he is a really talented left tackle, he has been far better than any of us could ask for.
Bryan Bulaga, Trai Turner and Mike Pouncey being hurt has really hurt the the team. Dan Feeney has shown flashes and has had good stretches but has not held up enough to be called solid. Forrest Lamp is showing the same holes, Ryan Groy has not been good and Trey Pipkins is the worst-graded tackle in the league, according to PFF.
Tevi has the best grade of anyone just listed with a 59.0 overall grade. Groy is next with a 54.1, Lamp with a 53.0, Feeney with a 46.9, Pipkins with a 40.9 and Tyree St. Louis, who has played 80 snaps, with a 37.7.
It has been bad. It will naturally improve as the injury luck improves. Justin Herbert has done his best with the shoddy blocking that he has had. Can he sustain this for 11 straight weeks if it stays like this? Probably not.
