Broncos at Eagles, Week 5 2025: who deserved to win?

The Broncos beat the Eagles 21–17, and it was no fluke: replayed with the way both teams actually played, the Broncos win 9 of 10.

An off day for the Eagles: their offense played far below its usual level. In a fresh game against the Broncos they would win 59% of the time; with this day’s form, 10%. The numbers

Before kickoff the Eagles were 60% favorites. The biggest swing (Q4, 5:23 left): Illegal Shift on the Eagles (Saquon Barkley), 4 yards, wiping out the play, worth 30 points of win probability to the Broncos.

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.

An off day for the Eagles

Their offense played far below its usual level. In a fresh game against the Broncos they would win 59% of the time; with this day’s form, 10%.

49 points apart for the Eagles: the gap is how differently this game went from what the two teams usually are.

UnitThis gameUsual levelBetter or worse than usual
Broncos offenseEPA per play gained +0.07 +0.11 worse by 0.04
Broncos defenseEPA per play allowed +0.01 +0.04 better by 0.03
Eagles offenseEPA per play gained +0.01 +0.13 worse by 0.12
Eagles defenseEPA per play allowed +0.07 +0.03 worse by 0.04

EPA (expected points added) per play on competitive snaps, turnovers left out because they are valued as luck. Usual level: the team’s earlier games this season plus half of last season, pulled toward the league average. One team’s defense and the other team’s offense are the same snaps, so one game can’t fully say whose day it was; it shows how far this one was from both teams’ norms.

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 +1.6 points to the Broncos: the final margin was Broncos by 4, without the luck Broncos by 2.4. 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.

  • W. Lutz, 55 yds made · 61% expected
  • J. Elliott, 31 yds made · 96% expected
  • W. Lutz, 36 yds made · 91% expected
Bar: expected chance of a make. Filled dot: made. Open dot: missed or blocked.

Penalties: Broncos 12 for 121 yards, Eagles 9 for 55 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
