Chargers: Grades for every player through four games

Chargers grades:
Keenan Allen
PFF Grade: 84.4
Stats: 34 receptions, 452 yards, three touchdowns, 108.2 passer rating when targeted
Keenan Allen has been bullying opposing defensive backs this season, so much so that referees feel obligated to call offensive pass interference on him.
With all the weapons falling to injury around Allen, it’s no wonder Philip Rivers has been targeting No. 13 over and over again. Allen is off to his best start in years, and the team has stayed close in games because of him.
Grade: A
Travis Benjamin
PFF Grade: 49.5
Stats: Four receptions, 17 receiving yards, zero touchdowns, 47.9 passer rating when targeted
I feel bad for Benjamin, because he’s often the punching bag of every Chargers fan. But then he does things like fumble the Saints game away (yea, remember that one?), personally safety himself against the Patriots, or drop the game-tying touchdown against the Texans.
Benjamin likely does more for this team than fans realize, but it’s hard to watch him get a target or run the football. If not for two incredibly clutch catches in Kansas City and a touchdown in Pittsburgh, Benjamin may not even be on the team this year.
Grade: D
Dontrelle Inman
PFF Grade: 69.0
Stats: Eight receptions, 132 receiving yards, zero touchdowns, 95.7 passer rating when targeted
At the time of writing this article, Inman suffered what appeared to be a quad injury. Not sure what his timetable is projected to be.
Inman had less snaps than Benjamin prior to the Dolphins game, but his increase led to his best game of the year, catching five passes for 76 yards. He’s not going to put those numbers up every game, but in the absence of someone like Mike Williams or Benjamin, he’s a solid target to have.
Grade: B-
