Chargers: Grades for every player through four games

Chargers grades:
Forrest Lamp
PFF Grade: 77.3 overall, 83.1 pass blocking, 71.9 run blocking
Stats: No sacks allowed, zero pressures, no penalties
Before you get all worked up, Lamp has played just 24 snaps on offense. Someone like Feeney, on the other hand, has played 260, and he has to play for an entire game and does not rotate fresh off the bench.
The dead-obvious solution to the Lamp problem is this: Put him at tackle. Left tackle, right tackle, north and south tackle, whatever, find a way to replace the two most glaring issues with the offense right now. Feeney and Schofield are at least performing well enough to not be benched, but the two tackles really need to be rotated out with Pittsburgh, Chicago, and Green Bay on the horizon.
Grade: n/a (not enough snaps)
Trey Pipkins
PFF Grade: 60.1 overall, 70.7 pass blocking, 58.5 run blocking
Stats: No sacks allowed, no pressures, no penalties
Like Lamp, Pipkins isn’t exactly out there dominating snap counts; in fact, he’s only had six this year, each of them coming at right tackle.
Grade: n/a (not enough snaps)
Virgil Green
PFF Grade: 53.3
Stats: Two receptions, 13 receiving yards, no touchdowns, 93.8 passer rating when targeted
Not much to go off here for Green, who is already being passed up by Lance Kendricks as an injury holds him out.
Grade: n/a (not enough snaps)
