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.

The Broncos won on an off day

They played far below what the matchup promised. In a fresh game against the Raiders they would win 74% of the time; with this day’s form, 31%.

43 points apart for the Broncos: 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 +0.04 better by 0.03
Broncos defenseEPA per play allowed −0.16 +0.06 better by 0.21
Raiders offenseEPA per play gained −0.16 +0.01 worse by 0.17
Raiders defenseEPA per play allowed +0.07 +0.09 better by 0.01

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

Broncos win 31% of them, Raiders 69%, counting the 4% still level after regulation as half each. The line is what actually happened: Broncos by 10.
