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 Ravens

Their defense played far below its usual level. In a fresh game against the Titans they would win 65% of the time; with this day’s form, 25%.

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

UnitThis gameUsual levelBetter or worse than usual
Titans offenseEPA per play gained +0.26 +0.14 better by 0.12
Titans defenseEPA per play allowed +0.16 +0.15 worse by 0.01
Ravens offenseEPA per play gained +0.16 +0.18 worse by 0.02
Ravens defenseEPA per play allowed +0.26 +0.07 worse by 0.20

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

0% treats it as skill, 100% as pure luck. The tick is our fit.

What counts

We tested momentum on 19,000 lucky breaks and found none, so it's off by default. Why
