Eagles at Cowboys, Week 16 2020: who deserved to win?
The Cowboys beat the Eagles 37–17, and it was no fluke: replayed with the way both teams actually played, the Cowboys win 9 of 10. The Eagles had the bounces: kicks alone were worth 11 points of win probability to the Eagles.
An off day for the Eagles: their defense played far below its usual level. In a fresh game against the Cowboys they would win 47% of the time; with this day’s form, 14%. The numbers
Before kickoff the Eagles were 59% favorites. The biggest swing (Q2, 5:56 left): G. Zuerlein made 20-yard field goal, worth 11 points of win probability to the Eagles.

Three other ways to ask
Each answers a different question, so none of them replaces the replay above.
Before kickoff
The closing betting line, turned into a probability. What everyone knew before the game.
Same teams, fresh 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.
Only coin-flips re-rolled
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 defense played far below its usual level. In a fresh game against the Cowboys they would win 47% of the time; with this day’s form, 14%.
Same teams, fresh game
Replay with same day's form
33 points apart for the Eagles: the gap is how differently this game went from what the two teams usually are.
| Unit | This game | Usual level | Better or worse than usual |
|---|---|---|---|
| Eagles offenseEPA per play gained | +0.02 | +0.04 | worse by 0.02 |
| Eagles defenseEPA per play allowed | +0.31 | +0.12 | worse by 0.19 |
| Cowboys offenseEPA per play gained | +0.31 | +0.12 | better by 0.19 |
| Cowboys defenseEPA per play allowed | +0.02 | +0.15 | better by 0.13 |
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
Eagles win 14% of them, Cowboys 86%, counting the 2% still level after regulation as half each. The line is what actually happened: Cowboys by 20.

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.
The kicks
How likely each kicker was to make that kick (his own record, the distance and the weather), and what happened.
- G. Zuerlein, 35 yds made · 93% expected
- G. Zuerlein, 20 yds made · 98% expected
- J. Elliott, 38 yds made · 91% expected
- G. Zuerlein, 21 yds made · 98% expected
Penalties: Eagles 12 for 115 yards, Cowboys 5 for 73 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
