David Amerson couldn't cover anybody.
DeAngelo Hall: Grade C
The Chargers stayed away from DeAngelo Hall, but on the rare occasions when he was called into action, he responded well.
The most notable example came near the goal line on the final drive in regulation. Hall was matched up on premier tight end Antonio Gates in single coverage.
He pressed him at the line and denied him a clean release to meet Rivers' fade pass.
Josh Wilson: Grade C
The secondary missed Josh Wilson after he left the field injured in the fourth quarter. He had delivered a solid performance from the slot.
Wilson was no liability in coverage while also being a nuisance on the blitz.
E.J. Biggers: Grade D
E.J. Biggers snared a vital interception that masked some other weaknesses in coverage.
David Amerson: Grade F
Despite claiming the defense's second interception, David Amerson has to warrant an "F" grade. That is thanks to the way he was beaten over and over again by fellow rookie Keenan Allen.
Amerson was unable to use his size to press receivers at the line, and he was frequently beaten by the first move. His inability to cope with Allen nearly cost the Redskins the game.
