The Chargers got a defensive-heavy showing at Monday’s practice, and Chris O’Leary’s group made sure Justin Herbert and the offense felt it.
Throughout the session, the defense kept landing blows. There were pass breakups, sticky coverage in the secondary and enough pressure on Herbert to turn the workout into one of the strongest defensive days of camp so far, according to Chargers beat reporter Kris Rhim.
That kind of outing fits what the Chargers had in mind when they made O’Leary one of their biggest offseason hires. In the first week of training camp, the new defensive coordinator is already seeing signs that the unit is moving in the right direction.
The personnel certainly gives him something to work with. Khalil Mack is back to headline the pass rush, Derwin James remains the centerpiece of the secondary after signing his contract extension this offseason, and Teair Tartt is holding down the middle of the defensive line. The Chargers also added young talent in the draft, including Akheem Mesidor, who has been drawing attention in camp with his burst off the edge.
What stood out on Monday wasn’t just the talent, though. It was the way the defense carried itself.
Herbert has already delivered his share of big throws during camp, but this practice belonged to the other side. The defensive backs were aggressive at the catch point, the rush kept the pocket unsettled and the whole unit looked like it was moving with purpose. That’s the kind of tempo O’Leary is trying to create.
A new system always comes with questions about how fast it can take hold, especially when there are new pieces expected to play real snaps. Early in camp, though, the Chargers don’t look bogged down by the install. The defense appears to be picking things up quickly.
One practice won’t tell the whole story, of course. Herbert and offensive coordinator Mike McDaniel are going to have their days, and the offense will almost certainly answer back at some point in camp. That’s how this time of year works.
But days like Monday still matter. They show a defense gaining confidence, communicating better and starting to play faster within the scheme. Stack enough of those practices together, and the payoff usually shows up when the games start.
The Chargers enter the 2026 season with real expectations after going 11-5 a year ago. If they want to keep climbing, they’ll need a defense that can support one of the league’s best quarterbacks instead of leaving everything on Herbert’s shoulders.
Monday was only one checkpoint in August, but it offered a clear glimpse of what the Chargers hope this group can become. If O’Leary’s defense keeps trending this way, Los Angeles may end up with one of its most complete units in years.

Chargers Camp Is Putting Several Surprise Roster Spots In Danger
Training camp has put the Chargers in the middle of a familiar late-summer sorting job, with final roster cuts looming and a handful of jobs still open in plain view. The staff is weighing whether to carry multiple quarterbacks, while also sorting through offensive-line combinations and testing out different defensive pieces under a new coordinator. For a team trying to tighten the depth chart in a hurry, the most interesting battles are often the ones happening farther down the lineup, where rookies and free agents are trying to turn practice reps into real security.
One of the clearest pressure points is on the offensive line, where several players have been getting a look at left guard instead of allowing the spot to settle early. The Chargers are also watching the edge closely as they trim the roster, because a veteran name that once felt like a safe bet is no longer in the same position he was when camp opened. With younger pass rushers pushing hard and versatility carrying extra weight across the roster, a few of these decisions could change the look of the team before the first game even arrives.

Justin Herbert Just Got The Kind Of Chargers Hype Fans Crave
Justin Herbert is heading into the season with the kind of optimism Chargers fans have been waiting for. Dan Orlovsky said on The Pat McAfee Show that he expects Los Angeles to field one of the NFLs top offenses, and it is easy to see why the buzz is building. The Chargers have tried to clean up the issues that held the unit back before, getting healthier up front while also adding reinforcements and bringing in tight end David Njoku in free agency.
The coaching change could matter just as much, with Mike McDaniel taking over as offensive coordinator and giving Herbert a fresh structure to work in. Even with the defensive coordinator gone for a head coaching job, the Chargers still bring back much of that side of the ball, which should help keep them competitive while the offense tries to take a real step forward. For a fan base that has heard plenty of promise before, this is at least the kind of outside validation that makes the offseason feel a little different. [Read more 🡒]
Chargers Rookies Are Already Putting Early Pressure On The Depth Chart
The Chargers are wrapping up their second full week of training camp, and the rookie class is already making some noise in a way that matters for a roster still taking shape. Akheem Mesidor has drawn attention for his work ethic and how prepared he looks, while Brenen Thompson and Travis Burke have also helped themselves with encouraging showings and the kind of practice habits coaches notice even before the pads fully tell the story.
Not every newcomer is at the same stage yet. Slaughter and Genesis Smith still have more proving to do, and the next stretch of camp should offer a better read once the contact ramps up and preseason games begin to sort out who is ready for real responsibility. For a Chargers team trying to sharpen its depth chart, the early returns are useful, but the more revealing tests are still ahead. [Read more 🡒]
