Chargers vs. Raiders: 4 biggest storylines ahead of Week 13 game

The Chargers square off against a Raiders squad that just fired offensive coordinator Chip Kelly in their Week 13 matchup on Sunday.

Here are a few storylines to track throughout the game.

How does Justin Herbert bounce back?

Herbert had the worst game of his career before the bye week, throwing for 81 yards and two interceptions in a miserable outing against Jacksonville. He'll have had two weeks to improve from that showing by the time the Chargers take the field on Sunday, and the opposing defense on the other side is an ideal one for LA's face of the franchise to get back on track. Herbert has thrown for 20 touchdowns and two interceptions and gone 7-3 in 10 career matchups against the Raiders.

Limiting Maxx Crosby

Trey Pipkins III had one of his best games of the season in Week 2, holding Crosby to only one pressure on 31 pass rush opportunities, per PFF. Los Angeles has been inconsistent in using tight ends Oronde Gadsden II and Tucker Fisk as helpers in pass protection since then, however, and Pipkins got more chip help in Week 2 because Joe Alt was still the Chargers' left tackle in that game. With Jamaree Salyer starting, it's likely LA will slide their help to that side, even with Crosby on the other. That will leave Pipkins to step up again.

Donte Jackson's INT streak

Jackson leads the Chargers with three interceptions and has grabbed a pick in each of his previous two games against the Raiders. He'll look to continue that streak on Sunday - LA held Geno Smith to 0-for-11 on passes over 10 yards in their Week 2 matchup and picked him off three times. Jackson has been the Chargers' most consistent corner this season, partially due to the health of Tarheeb Still, and should have a decent matchup against a patchwork Raiders receiving corps.

Changing offensive identity

With Chip Kelly out and interim offensive coordinator Greg Olson in, expect the Raiders to lean more on their premium talent on Sunday. Rookie running back Ashton Jeanty has only gone over 100 yards once this season, in Week 4, but he had 108 yards from scrimmage last week against the Browns. Tight end Brock Bowers has struggled with a knee injury at times this season, but is now fully healthy and should be the focal point of the passing game. One key injury may be center Jordan Meredith, who missed practice Wednesday with an ankle injury.
