Arizona went into SoFi Stadium as 8.5-point road underdogs and beat the Chargers 26-14\. The defense delivered that win. It just wasn't the pass rush that did it.

## The number that turned the game

On 21 rushing attempts, the Chargers gained 81 yards against Arizona's defense in Week 1 — **3.86 yards per carry**, at **\-0.325 EPA per rush**. On a 21-carry sample, in isolation, that number is noise. It only means something measured against what this defense has actually allowed on the ground in recent years.

## Four years of history as the baseline

| Season           | YPC allowed | EPA/rush allowed | Rushes faced |
| ---------------- | ----------- | ---------------- | ------------ |
| 2022             | 4.74        | \-0.008          | 429          |
| 2023             | 4.79        | +0.016           | 510          |
| 2024             | 4.77        | +0.046           | 453          |
| 2025             | 4.83        | +0.008           | 456          |
| **2026, Week 1** | **3.86**    | **\-0.325**      | **21**       |

This history isn't the story — it's the yardstick. From 2022 through 2025, Arizona let opposing runners average at least 4.7 yards a carry every single season, with EPA per rush allowed hovering right around break-even. That's the profile of a defense that simply didn't stop the run. In the 2026 opener, the Chargers ran for almost a yard less per carry than that four-year floor, and every one of those 21 rushes cost them, on average, about a third of an expected point.

## Hampton, carry by carry (Chargers)

Rookie first-rounder Omarion Hampton carried the ball 12 times for 43 yards in the opener, averaging **\-0.385 EPA per carry**. Play by play:

- 1st-and-10: 2 yards (-0.38 EPA)
- 1st-and-10: 0 yards (-0.51)
- 3rd-and-3: 8 yards, touchdown (+2.16)
- 1st-and-10: 14 yards (+0.74) — his longest gain
- 2nd-and-10: run for -1 yards, fumble forced by Andrew Wingard, recovered by Will Johnson at the ARI 34 (-5.20)
- 1st-and-10: 2 yards (-0.48)
- 2nd-and-2: 6 yards (+0.03)
- 1st-and-10: 6 yards (+0.24)
- 1st-and-10: 2 yards (-0.47)
- 2nd-and-4: 6 yards (+0.41)
- 2nd-and-15: -1 yards (-1.02)
- 2nd-and-1: 2 yards (-0.15)

Strip out the touchdown and the other 11 carries netted 35 yards on mostly negative plays, capped by the fumble. It wasn't a shutdown performance on every snap — Hampton still broke a 14-yard run — but the overall shape in his NFL debut against this defense was a back who couldn't find room and, on one carry, gave the ball away.

## Every rusher finished in the red

Hampton wasn't alone. Justin Herbert scrambled five times for 29 yards at **\-0.21 EPA per carry**, and Kimani Mitchell added four carries for 9 yards at **\-0.29 EPA per carry**. Those were the only three rushers the Chargers used in the opener, and all three finished the game with negative EPA per carry — there was no corner of the Chargers' ground game that worked in Week 1.

## What the tackle sheet says about the pass rush

Sweat's name shows up once in the run-play log from the opener: a shared tackle, alongside Levi Collier, on Hampton's third-quarter carry that lost a yard on 2nd-and-15\. That's a stop against the run, not a pass-rush win, and it's the only credited appearance for him among Hampton's 12 carries. Elsewhere on the ground, Jack Gibbens was in on the tackle for Hampton's 14-yard gain, and Budda Baker, a safety, made the stop on a 6-yard carry. In the run-fit column, a linebacker and a safety showed up as much as anyone up front.

None of that tells us what Sweat or Arizona's edge rushers did against the pass in Week 1 — that's a different box score, and a fair one to look at separately before drawing conclusions about the pass-rush investment. What the run-play log does show clearly is that on early downs, it was Wingard, Gibbens, and Baker showing up around the line of scrimmage as much as anyone up front.

## What's next, and what this is and isn't

 Twenty-one carries is not a season-defining sample, and nothing here proves Arizona has fixed a run defense that allowed 4.7-plus yards a carry for four straight years. It's entirely possible Week 1 was a product of game script or plain variance. Whether that holds up as the 2026 season goes on is a separate question, and one more games will have to answer.
