Chargers Defense Faces Its First Real Test In Buffalo

The Chargers' emerging run defense faces a pivotal test as they aim to stifle the dominant ground attack of the high-flying Bills in their first away game of the season.

The Chargers are heading out for their first road game of the season in Week 3, and they’re walking straight into their toughest assignment yet.

Buffalo has opened 2-0, piled up 77 points, and looks every bit like the kind of team people expected to see. The Bills have also been pounding teams on the ground, turning into one of the league’s most productive rushing attacks. That makes this a brutal measuring stick for a Chargers team that has started 0-2 but has at least found something to build on in one important area.

After two weeks, the Chargers’ run defense has quietly been one of their best traits. That showed up in Week 2 against the Raiders, when Los Angeles limited them to 57 rushing yards on 29 carries. Head coach Jim Harbaugh came away encouraged by what he saw.

"The play of the defensive line, play of Derwin [James], the guys, it was very good. There was a run wall there," Harbaugh said.

The numbers back up that impression. Through two games, the Chargers rank fifth in defensive EPA per play against the run at -0.257. Pro Football Focus has them at 79.2 defensively, and they’ve given up only three explosive runs of 10 or more yards, which is tied for second in the NFL.

Still, the Bills bring a completely different kind of stress test. Josh Allen and James Cook headline a Buffalo ground game that’s averaging 144.5 rushing yards per game, good for fifth in the league. As a team, the Bills are putting up 5.1 yards per carry and have already racked up 289 rushing yards over the first two weeks.

Cook has carried over his 2025 form, averaging 5.6 yards per attempt. Allen, meanwhile, is already up to four rushing touchdowns and remains a major problem near the goal line.

For the Chargers, the formula is simple. If they want a real chance to win, they have to hold up against Buffalo on the ground.

Chargers Get A Needed Break As Week 3 Offensive Questions Grow

The Chargers got a little bit of relief this week as their offense continues to sort itself out heading into Week 3. Tight end Charlie Kolar will not go on injured reserve after surgery, which at least keeps the door open for his return later in the season, even though he will miss the upcoming game. It is the kind of update that does not solve anything immediately, but it does matter for a team trying to keep its pass-catching depth intact while the bigger questions around the offense linger.

Jim Harbaugh also confirmed that the Chargers are bringing wide receiver Marquez Valdes-Scantling up to the active roster from the practice squad, giving them another veteran option to work with right away. For a group looking for answers and a little more stability, the move adds some insulation in the short term, even if the larger issue is still how quickly this offense can find its footing.

Chargers Defense Is Already Making A Veteran's Role A Flashpoint

The Chargers rough start has put every part of the roster under a microscope, and the defense is no exception. After two losses to open the 2026 season, frustration around the building and among fans has only grown, with the coaching staff already drawing fresh scrutiny. Within that tension, the cornerback rotation has become one of the clearest signs that no role is guaranteed anymore.

Chris OLearys decision to bench Donte Jackson in Week 2 underscored how quickly things can shift for a veteran who was a strong part of last seasons defense. Jacksons snaps have already been trimmed as the Chargers try to sort out their rotation, and OLeary has made the standard plain: playing time goes to the best performers. For a team still searching for its footing, that makes Jacksons place in the mix one of the more interesting questions on the defense right now. [Read more 🡒]

Justin Herbert Pushes Back As Chargers Leadership Debate Heats Up

Justin Herbert took questions at his midweek press conference ahead of Week 3 with the Chargers already trying to steady a rough start. After two home losses to open the 2026 season, the conversation around the team has shifted quickly from results to accountability, and Herbert made it clear he does not buy the idea that he has been quiet when it comes to leadership.

Herbert said the focus has to be on moving forward and cleaning up the mistakes that have piled up early. With a demanding schedule still ahead, the Chargers do not have much room for drift, and the scrutiny around their quarterbacks voice is only going to grow if the losing continues. [Read more 🡒]
