Dolphins at Broncos, Week 11 2020: who deserved to win?
The Broncos beat the Dolphins 20–13, and the replays back it up: with the way both teams actually played, the Broncos win 9 of 10.
An off day for the Dolphins: their offense played far below its usual level. In a fresh game against the Broncos they would win 54% of the time; with this day’s form, 12%. The numbers
Before kickoff the Dolphins were 62% favorites. The biggest swing (Q1, 12:25 left): Defensive Holding on the Broncos, 5 yards, wiping out the play, worth 13 points of win probability to the Dolphins.

Your call
Did the Broncos earn it, or get lucky?
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 Dolphins
Their offense played far below its usual level. In a fresh game against the Broncos they would win 54% of the time; with this day’s form, 12%.

| Unit | This game | Usual level | Better or worse than usual |
|---|---|---|---|
| Dolphins offenseEPA per play gained | −0.10 | +0.10 | worse by 0.20 |
| Dolphins defenseEPA per play allowed | +0.11 | +0.14 | better by 0.03 |

| Broncos defenseEPA per play allowed | −0.10 | +0.08 | better by 0.18 |
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
Dolphins win 12% of them, Broncos 88%, counting the 2% still level after regulation as half each. The line is what actually happened: Broncos by 7.

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.
- B. McManus, 29 yds made · 97% expected
- J. Sanders, 41 yds made · 87% expected
- B. McManus, 47 yds made · 79% expected
- J. Sanders, 53 yds made · 66% expected
Penalties: Dolphins 5 for 50 yards, Broncos 8 for 70 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.
