Five Weeks, Two Contingency Plans, One Pattern the Chargers Cannot Escape

The offensive tackle depth chart currently lists Trevor Penning as questionable, followed by Alex Harkey and Isaiah World. I wrote about that depth chart last week, and the week before, and the situation has not improved — it has simply acquired a new layer. Rashawn Slater's high ankle sprain means the Chargers have now burned through two separate contingency plans along the offensive line in roughly five weeks, a pace of structural failure that no amount of roster creativity can paper over indefinitely.

Here is the number that keeps pulling me back: the 2025 Chargers won ten more percentage points of their games than their actual scoring margin said they should. That gap was built almost entirely on going 6–2 in games decided by a touchdown or fewer — a team that won close games at a rate that almost never sustains itself. It didn't. The December collapse arrived on schedule. What that record obscured was a roster with no real redundancy, a team whose margin for error was already zero before a single player got hurt. The offensive line injuries are not bad luck layered on top of a sound structure. They are the sound structure, finally visible.

The contingency timeline is worth tracing plainly. Tyler Biadasz goes down in August with a torn ACL — season over before it starts. Slater misses six straight practices in training camp, recovers, declares himself fully healthy for Week 1, then suffers a high ankle sprain that sends the Chargers back to the same emergency depth they spent all of August scrambling to assemble. The tackle depth chart that results — Penning at questionable, Harkey and World behind him — was the fallback plan. There is no plan behind the fallback.

What makes this particularly difficult is the position itself. Left tackle is not a spot where you absorb attrition through rotation. It is a one-man job, and when that man is Slater — one of the better blindside protectors in the AFC — his absence does not create a competition, it creates a problem. Justin Herbert has thrown for nearly 3,900 yards and 26 touchdowns in 17 games, the kind of production that requires a clean pocket more weeks than not. The offensive line's job is to make Herbert's talent translatable. Right now, that job is being done by players who were not supposed to be doing it.

My read is that the deeper issue is not any single injury but the organizational habit of building to the first layer of depth and stopping there. The tight end room collapsed the same way — Njoku and Kolar both on injured reserve within days of each other, leaving the Chargers to sign Hayden Rucci and piece together whatever that room has become. The cornerback group has one player with meaningful snaps behind Donte Jackson. The linebacker depth behind Troy Dye is functionally thin. These are not isolated position groups having bad luck simultaneously. They are the same problem wearing different jerseys. A team that outperformed its point differential by ten percentage points in 2025 needed everything to go right to repeat it. Almost nothing has.
