Commanders at Cowboys, Week 2 2026: who deserved to win?

The Cowboys beat the Commanders 37–20, and the replays back it up: with the way both teams actually played, the Cowboys win 8 of 10.

Before kickoff the Cowboys were 60% favorites. The biggest swing (Q1, 5:52 left): Defensive Offside on the Commanders (Charles Omenihu), 5 yards, wiping out the play, worth 8 points of win probability to the Cowboys.

Most of the distance between a forecast and a final score is luck: even with both teams’ strength known exactly, one game’s bounces, kicks and calls move the final margin by about ±12 points. This game was played before our forecasts went live, so this one was made afterwards, the same way, from only what was known before kickoff. How our predictions have done

Three other ways to ask

Each answers a different question, so none of them replaces the replay above.

The closing betting line, turned into a probability. What everyone knew before the game.

The line plus what this game showed, weighted by how much one game can tell. It stays close to the line because one game says little.

Every kick, fumble bounce, drop, conversion and judgment call redrawn; everything else fixed. The narrowest view of luck.

How 4,000 replays ended

Where the luck was

What the luck was worth

Every lucky and unlucky play, weighted by the moment it happened: its swing in win probability, added up by kind. A missed kick in a decided game counts for nothing; the same kick at the end of a tie game can be most of a win.

Swings add up across a game, so in one that went back and forth they can pass 100%. On the scoreboard the same luck was worth +2.9 points to the Cowboys: the final margin was Cowboys by 17, without the luck Cowboys by 14.1. Luck shares are the fitted ones (how much of each kind is luck).

The kicks

How likely each kicker was to make that kick (his own record, the distance and the weather), and what happened.

  • B. Aubrey, 25 yds made · 100% expected
  • D. Stevens, 27 yds made · 97% expected
  • D. Stevens, 47 yds made · 79% expected
  • B. Aubrey, 44 yds made · 86% expected
  • D. Stevens, 51 yds missed · 72% expected
  • B. Aubrey, 60 yds made · 72% expected
Bar: expected chance of a make. Filled dot: made. Open dot: missed or blocked.

Penalties: Commanders 5 for 38 yards, Cowboys 5 for 32 yards

Every accepted flag, in order, and what it did to the helped team’s chance of winning at that moment, including any play it wiped out (points on the scoreboard in grey). A flag in a decided game is worth nothing; one at the turn of a close game can be worth most of a win. Judgment calls count half toward luck; pre-snap fouls, which repeat, don’t count.
