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 Texans

Their offense and defense both played far below their usual level. In a fresh game against the Titans they would win 33% of the time; with this day’s form, 2%.

31 points apart for the Texans: 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 +0.30 +0.10 better by 0.19
Titans defenseEPA per play allowed −0.50 +0.10 better by 0.60
Texans offenseEPA per play gained −0.50 +0.04 worse by 0.54
Texans defenseEPA per play allowed +0.30 +0.14 worse by 0.15

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.
