The Chargers Won Eleven Games and Still Have Questions

Eleven wins and a playoff berth is a good year by any reasonable measure. But the most useful thing you can do with a won-loss record is ask how much of it was earned. The Chargers' point differential in 2025 — plus-28 on the season — translates, through our fitted points-per-win model, to 9.3 structural wins. They won 11. That 1.7-win gap between what the scoreboard said and what the underlying math suggested is called the luck delta, and it's the single most predictive number in this entire write-up.

The mechanism behind that delta was the one-score ledger. Los Angeles went 6-2 in games decided by eight points or fewer. That's an excellent record, and it's also the kind of record that tends to regress — not because the team is bad, but because close games involve a level of variance that even elite teams can't consistently bend in their favor. A 6-2 mark in one-score games isn't proof of clutch; it's more often proof that the ball bounced right. The structural read headed into 2026 is 9.3 wins, not 11, and that context should color everything that follows.

The defense was genuinely good. Opponents produced -0.10 EPA per pass attempt and -0.08 EPA per carry against this unit — both figures comfortably in negative territory, which means the Chargers were actively destroying value on opposing drives, not merely limiting it. That kind of two-dimensional defensive efficiency is hard to manufacture and harder to fake over a full season. It's the real foundation of the 11-win year, more than any single turnover or highlight-reel play.

The offense was a different story. At -0.04 EPA per pass attempt and -0.01 per carry, Justin Herbert's unit was essentially break-even — not damaging itself, but not generating the kind of per-play advantage you'd expect from a team that finished 11-6. The situational numbers made it worse: a 48% conversion rate on third and fourth downs is functional, but a -0.12 EPA per play in the red zone is where the offense genuinely left points on the field. The defense carried the team to the scoreline; the offense needed the defense to keep doing exactly that.

Jim Harbaugh's decision index tells a quiet story of its own. His model-suggested go rate on fourth down was 30.9%; his actual rate was 10.6%. The result: roughly 0.35 expected wins left on the field from in-game decisions alone, against a model that agreed with his calls only 72.3% of the time. Harbaugh is a brilliant football mind by reputation, but the decision model rates him as a coach who costs his team something at the margin — not enough to override roster quality, but real enough to note.

The arrivals were affordable and functional. Tyler Biadasz (C, from Washington) comes in at $10M APY, worth 0.77 market wins. Charlie Kolar (TE, from Baltimore) at $8.1M buys 0.60 market wins of tight end production. Cole Strange (LG, from Miami) at $6.5M slots in at left guard — notable mostly because the man he replaced cost more than twice as much. Dalvin Tomlinson (IDL, from Arizona) rounds out the group at $6.2M and 0.43 market wins. These are solid-roster pieces: reasonably priced, low-ceiling, no one who changes the ceiling of the offense or defense by themselves.

The departures stung more. Odafe Oweh left for Washington on a $24M APY deal — 1.98 market wins walking out the door, which is the kind of edge rusher production you don't replace with a first-round pick and hope for the best. Zion Johnson went to Cleveland at $16.5M APY (1.33 market wins). Alohi Gilman signed with Kansas City at $8M (0.59 market wins), and Benjamin St-Juste joined Green Bay at $5M (0.33 market wins). The net offseason movement on a market basis is -1.97 wins. On a production basis, where we don't yet have the data to pin current output to each contract, the model reads zero — but the market signal is hard to dismiss.

The draft class is anchored by Akheem Mesidor, a pass rusher out of Miami taken 22nd overall (1.19 chart wins). That pick was clearly aimed at backfilling the Oweh departure — whether it succeeds at that price is a question for training camp, not a draft board. Jake Slaughter (C, Florida, pick 63, 0.78 chart wins) is an interesting pairing with Biadasz — the team is clearly addressing interior line depth after losing Johnson. The rest of the class — Brenen Thompson, Travis Burke, Genesis Smith, Nick Barrett, Logan Taylor, Alex Harkey — accounts for 1.77 combined chart wins spread across rounds four through six. Depth, not stars.

Two contract verdicts carry the WATCH label. Derwin James re-signed for three years at $25.2M APY — the 100th percentile of the safety market — at age 30, with a relatively clean exit at $6M dead money in 2028. The price is real; the question is whether the safety market rises enough by 2027 to make this look reasonable in hindsight. Khalil Mack is on a one-year deal at $18M APY (93rd percentile for edge rushers) at age 34. One year limits the exposure; the aging curve at that position and age makes every snap worth watching.

Honest accounting says this offseason hurt, at least on paper. The market-basis net of -1.97 wins represents the gap between what left and what arrived in terms of established production value. Oweh's edge rush production alone was the most expensive departure, and the Chargers replaced it with a first-round rookie — a bet on upside and development rather than a like-for-like swap. That's a defensible strategy; it's not a neutral one.

The cap posture is worth a look. Justin Herbert sits at 15.2% of the cap — a quarterback at that tier who consumes that share of the salary structure is, relatively speaking, a reasonable deal; it's the lowest of the four biggest hits on the roster. Derwin James at 8.1% and Rashawn Slater at 7.8% are the next two, which means the team is paying significant market rates for a safety and a left tackle before it gets to the skill-position spending. The safety group's cap concentration is the most extreme on the roster — a Z-score of 2.48, meaning it's a statistical outlier relative to the league — and James is the obvious reason why.

The one genuine bright spot on the ledger is Ladd McConkey. At 0.9% of the cap against an 83rd-percentile production mark, he's the only rookie windfall flagged in the brief, and he's a meaningful one. A wide receiver producing at that level while consuming that little cap space is the kind of structural advantage that affords flexibility elsewhere — and the Chargers need that flexibility given where their proration obligations sit ($68.8M in future dead money already baked into the ledger). The ledger, overall, reads as a team that maintained rather than improved.

The arithmetic is straightforward, even if the conclusion is uncomfortable for a team coming off 11 wins. Start with the structural base derived from the 2025 point differential: 9.3 wins. Add the offseason production delta: zero, because the arrivals and departures net out that way on the production model. Add the coach decision delta: also zero — Harbaugh remains, and the existing gap between his decision-making and the model's recommendation was already baked into the 2025 result. The structural projection for 2026 is 9.3 wins. That's an accounting projection from the ledger — not a pick, not a betting recommendation, and not a prediction that accounts for schedule, injuries, or any of the other things that make football football.

The falsifier is clear: if the Chargers win 11 or more games again in 2026, this read is wrong, and the most likely explanations would be continued overperformance in one-score games, a meaningful offensive EPA improvement driven by Herbert's development in the system, or Mesidor contributing genuine edge rush production faster than rookie curves typically allow. If they finish at eight or nine wins, the structural model will have told the story correctly. The 2025 record was real; so is the regression math.

The brief doesn't flag meaningful vacated opportunity from departures on the offensive side — Oweh, Gilman, Johnson, and St-Juste were defensive players, so there's no target volume to redistribute. The one arrival with offensive relevance is Charlie Kolar, whose 2025 production line (15 targets, 36.2 PPR points) suggests a depth tight end rather than a featured one. At $8.1M APY, the market isn't pricing him as a starter either. If the Chargers find creative ways to use him, the volume could grow — but the brief doesn't give us a baseline that supports aggressive fantasy positioning.

The real case in this offense belongs to Ladd McConkey, though the brief limits how far we can take it. What we know: 83rd-percentile production at 35th-percentile pay, on a rookie contract. That combination — efficiency the market hasn't caught up with — is the structure of a sleeper. The question the brief doesn't answer is volume, and without a vacated-targets number to anchor the opportunity argument, the efficiency case stands on its own merits. That's enough to pay attention; it's not enough to make a strong forward claim without more data.

No aging flags were generated by the brief, so there are no production-fade fades to make from this roster on the offensive side. The honest answer for DFS and fantasy purposes is that this is a defense-first team whose offense was merely functional in 2025, and the arrivals don't dramatically change that picture. McConkey is the asset worth tracking. Everything else waits for training camp to give us something firmer to work with.

Everything above traces to a live instrument, and the receipts stay public: the GM boards carry Jim Harbaugh's decision card, the team's cap posture ($68.8M already charged to future caps), and every contract verdict with its falsifier and review date — including Derwin James (WATCH), Khalil Mack (WATCH). When the season grades these reads, the grades post whether they flatter us or not.
