Bengals at Chargers, Week 11 2024: who deserved to win?

The Chargers beat the Bengals 34–27, but it was a coin flip: replayed with the way both teams played, the Chargers win 5 of 10. Luck ran their way: kicks alone were worth 34 points of win probability to the Chargers.

Before kickoff it was a pick’em. The game turned on a luck play (Q4, 1:52 left): E. McPherson missed 51-yard field goal, worth 21 points of win probability to the Chargers. The biggest single swing (Q4, 9:57 left): Roughing the Passer on the Chargers (Otito Ogbonnia), 15 yards, wiping out the play.

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

Bengals win 50% of them, Chargers 50%, counting the 4% still level after regulation as half each. The line is what actually happened: Chargers 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.

Swings add up across a game, so in one that went back and forth they can pass 100%. On the scoreboard the same luck was worth +0.7 points to the Chargers: the final margin was Chargers by 7, without the luck Chargers by 6.3. Luck shares are the fitted ones (how much of each kind is luck).

The kicks

How likely each kicker was to make that kick (his own record, the distance and the weather), and what happened.

  • E. McPherson, 26 yds made · 99% expected
  • E. McPherson, 27 yds made · 99% expected
  • C. Dicker, 19 yds made · 100% expected
  • C. Dicker, 53 yds made · 74% expected
  • E. McPherson, 48 yds missed · 80% expected
  • E. McPherson, 51 yds missed · 75% expected
Bar: expected chance of a make. Filled dot: made. Open dot: missed or blocked.

Penalties: Bengals 8 for 56 yards, Chargers 5 for 50 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 toward luck, pre-snap fouls mostly don’t. How calls are valued
