Akheem Mesidor is walking into his rookie year with the kind of expectations that usually come with proven veterans, not first-year players. The Chargers aren’t hiding what they want here: while Khalil Mack is still the starter, they’re betting Mesidor can grow into the franchise’s next major pass-rushing piece.
That’s a tall ask for any rookie, and especially for an edge rusher trying to make the jump from college football to the NFL. But Los Angeles didn’t land in this spot by accident. The team spent the offseason thinking about Mack’s future, and everyone around the organization knows he is far closer to the end of his career than the beginning.
The good news for Mesidor is that he won’t be thrown into the fire alone. He joins a defensive front that already has real bite, with Tuli Tuipulotu emerging as a legitimate pass-rushing threat and Mack still producing when he’s on the field. That gives the Chargers a chance to bring Mesidor along the right way instead of asking him to be the face of the rush from day one.
Mack’s presence could matter just as much off the field as on it. His reputation is built on elite technique, preparation and consistency, and those are the kinds of habits a rookie can absorb by being in the room every day.
For Mesidor, that kind of apprenticeship could speed up the learning curve. For the Chargers, it offers a path toward a smoother transition at one of the most important spots on defense.
New defensive coordinator Chris O’Leary also steps into a situation that should help Mesidor find his footing. The roster around him is already loaded with playmakers, and with Tuipulotu drawing attention on one side and Mack still able to collapse the pocket, Mesidor should get chances to work in one-on-one situations when he rotates in.
The expectation isn’t that he comes out and racks up double-digit sacks right away. What the Chargers need is something more measured and more realistic: steady progress.
If Mesidor can pressure quarterbacks, hold up against the run and become a reliable rotational defender, that would count as a strong rookie season. Anything extra would just be a nice bonus.
There’s also a bigger reason this matters. Mack is on borrowed time, and the Chargers can’t afford to wait until he’s gone to figure out who carries the torch next. Getting Mesidor developed now gives the team a chance to protect one of the defense’s most valuable positions without having to rebuild the pass rush from scratch in a year or two.
The Chargers believe championship-caliber defenses are built on the ability to consistently pressure opposing quarterbacks. They already think they have one star in Tuipulotu. If Mesidor becomes what they think he can be, Los Angeles could be looking at one of the league’s most dangerous edge-rushing tandems for years to come.

Chargers May Have An Undrafted Rookie Pushing For A Crucial Role
Jacob Spomers path to the Chargers is the kind of long, winding offensive line story that usually starts with patience and ends with a camp invite. The former Liberty High School and Diablo Valley College standout made his way to Fresno State, where he kept climbing after a move to center and eventually earned First-Team All-Mountain West honors in 2025.
For Los Angeles, the appeal is obvious: Spomer arrives as an undrafted rookie with a chance to carve out a real role up front. His college rise came after a torn ACL slowed his progress, but the Chargers are giving him a shot to compete for a spot that could matter more than it looks on paper once camp battles start sorting themselves out.

Chargers Defense Could Look Very Different Under Chris O'Leary
Chris OLeary is back in the Chargers defensive chair for 2026, and with Jesse Minter off to Baltimore, the structure of this unit could change in a meaningful way. OLearys return comes after a season at Western Michigan, where he showed a willingness to heat up opposing quarterbacks more aggressively than the Chargers did under Minter, giving this defense a different personality than the one that helped define the last couple of years.
The biggest question now is how much of that approach carries over to Los Angeles, especially with a linebacker group that looks deep enough to force real competition when camp opens. OLearys track record suggests more pressure could come from the second level and from the slot, which would put players like Derwin James Jr. in the middle of the conversation as the Chargers sort out how they want to attack in 2026.

Chargers Defense Faces A Real Test Under Chris OLeary
Chris OLeary steps into a good situation on paper, taking over a Chargers defense that already has a sturdy core and a familiar structure around it. With Derwin James, Khalil Mack, Tuli Tuipulotu and Daiyan Henley in place, along with help from Tarheeb Still, Cam Hart, Akheem Mesidor and Teair Tartt, there is enough talent to keep the unit competitive while OLeary settles in.
The bigger question is how smoothly he can turn that foundation into week-to-week production once the games start forcing quick decisions. The Chargers are not asking him to rebuild from scratch, but they are asking him to keep the defense sharp in the moments that matter most, and that is where his first real test begins. [Read more 🡒]
