LA Chargers Linebackers: C
Any game where a team rushes for as much as the Cowboys did simply isn't a good game for the linebackers regardless of the other considerations. That being said, Kenneth Murray did get a critical run stop late in the game and had a nice performance after having the wind knocked out of him early in the game.
Kyzir White being invisible most of the game other than a pass interference call was concerning though. He had a solid preseason as well as a very good effort against Washington, so it was a shame to see him practically locked out of this one.
LA Chargers Secondary: A-
The best performance was the secondary hands down. Yes, on some level they were assisted by the Cowboys constantly going to the ground game. Michael Davis, Derwin James, and Asante Samuel Jr. were still very impressive on their own merits though. The rookie corner got his first NFL interception on Prescott early in the game while Davis shut down Amari Cooper (three receptions, 24 yards).
James was James when it came to pass coverage and locking opposing receivers down. This was a huge bounce back effort for Nasir Adderley in particular. Dealing with a shoulder injury, the Philadelphia native led the team in tackles and had a huge pass deflection (intended for Blake Jarwin) that limited the Cowboys to a field goal. Yes, he should've came down with the pick, but it kept the Chargers in business nonetheless.
