Texans at Rams, Week 1 2025: who deserved to win?

The Rams beat the Texans 14–9, but it was a coin flip: replayed with the way both teams played, the Rams win 6 of 10. Luck ran their way: fumble bounces alone were worth 10 points of win probability to the Rams.

Before kickoff the Rams were 60% favorites. The biggest swing (Q2, 13:58 left): Offensive Holding on the Rams (Tyler Higbee), 10 yards, wiping out the play, worth 18 points of win probability to the Texans.

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.

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 +2.3 points to the Texans: the final margin was Rams by 5, without the luck Rams by 7.3. 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.

  • K. Fairbairn, 51 yds made · 74% expected
  • K. Fairbairn, 45 yds made · 83% expected
  • K. Fairbairn, 53 yds made · 71% expected
Bar: expected chance of a make. Filled dot: made. Open dot: missed or blocked.

Penalties: Texans 11 for 80 yards, Rams 7 for 60 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 toward luck, pre-snap fouls mostly don’t. How calls are valued
