Chargers: Grades for every player through four games

Chargers grades:
Justin Jackson
PFF Grade: 77.2 overall, 82.0 rushing, 72.7 receiving
Stats: 18 carries, 142 rushing yards (7.9 average), no touchdowns. Six receptions, 13 receiving yards, no touchdowns.
Jackson has been incredibly productive as a runner, with visions and cuts that draw the praise of every fan. Unfortunately, that role diminishes with the return of Melvin Gordon (as well as his own injury), though it’s hard to imagine him not getting a few snaps per game.
Grade: B+
Joey Bosa
PFF Grade: 90.2 overall, 80.0 run defense, 85.5 pass rush
Stats: 16 solo tackles, three sacks, 13 stops, 10 hurries, 16 total pressures
Bosa shows why focusing on sack totals isn’t the best way to evaluate a pass rusher. On top of his pass rush win percentage (the highest in the NFL right now), Bosa has also improved tremendously as a run defender. His dual-threat ability now makes him not just one of the best pass rushers in the league, but also one of the most complete defenders in football.
Grade: A-
Isaac Rochell
PFF Grade: 61.2 overall, 60.3 run defense, 59.1 pass rush
Stats: No solo tackles, one sacks, one stop, one hurry, two total pressures
It’s a small role for Rochell, but he’s started to show up on special teams. In back-to-back weeks, No. 98 was seen flying down the field for a key tackle, including one forced fumble. He’s not doing much, but with Melvin Ingram out for a few weeks, he may step up into a bigger role rotating with Uchenna Nwosu.
Grade: C
