The Patriots beat the Bengals 16–10, but it was a coin flip: replayed with the way both teams played, the Patriots win 5 of 10. Luck ran their way: drops alone were worth 4.6 points to the Patriots.

Before kickoff the Bengals were 72% favorites. The biggest swing (Q2, 5:19 left): the Bengals were stopped on 3rd & 11, worth 10 points of win probability to the Patriots.

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.

How 4,000 replays ended

Patriots win 47% of them, Bengals 53%, counting the 7% still level after regulation as half each. The line is what actually happened: Patriots by 6.

Where the luck was

Take the luck out

The final margin was Patriots by 6. Remove the luck, one kind at a time, and it becomes Bengals by 2.5.

Each row takes one kind of luck out of the margin. Color shows which team it helped. Luck shares are the fitted ones (how much of each component is luck).

The kicks

  • J. Slye, 32 yds made · 95% expected
  • J. Slye, 35 yds made · 92% expected
  • J. Slye, 37 yds made · 91% expected
  • E. McPherson, 51 yds made · 74% expected

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