How the game was won
The model and the market were 7.6 win-probability points apart on the average play, and 18 apart at the widest — with the model the more convinced about Chiefs.

The solid line is the betting market's home win probability; the dashed line is the play-by-play model's. The shaded band between them is the disagreement — emerald where the model liked the home team more, red where it liked the away team more. Drag across the curve or use arrow keys to replay the game; gold diamonds mark the biggest swings.

How the points landed
The margin ledger
JuJu Smith-Schuster's 4-yard touchdown catch with 4:03 left in the 2nd put Kansas City Chiefs ahead for good. The lead never changed over the 7 scores that followed.
Chiefs ahead 6–3 on categories, including the biggest gap of the duel — turnovers.
Expected points added, per play
The centre line is an average play. A bar to the right of it is a side that gained more than the situation was worth; a bar to the left is a side that lost ground. All six bars share one scale, ±0.41 points.

The Read
12 of 12 readings cleared their snap floor and were tested against four comparisons: this week's whole slate, the team's own season, the week before, and the team's own ordinary spread. Every bar below is set in that team's own week-to-week swing, never in league points — one team's swing runs 1.6 to 3.1 times the entire league's spread.
Too few to read
1 of 12 readings cleared their snap floor in this game, which is under the three this column needs before it will draw the rule. The readings themselves stand.
BAL's early-down pass rate, 71.8%, sat 25.9 points above their season number of 45.9% — they passed early by 2.0 times their own 12.8-point weekly swing.

Was this normal for them?
12 of 12 readings cleared their snap floor. Every deviation below is measured in that team's own game-to-game swing, not in league points — because one game's swing runs from 1.6 to 3.1 times the whole league's spread.

4 players played under 8 snaps, so their shares read as a dash rather than a number. 5 lines have no expected-points read and sit off the plane.
Expected points are modelled in full PPR, so the “vs expected” column stays in that unit whichever format the pills are set to. Switching the pills changes the points column, not the plane.
The field map
Every snap, where it happened
The whole game as one hundred yards. The Chiefs attack right, the Ravens attack left, so a change of possession is a reversal you can see. Reading down is the order the snaps were played — not the clock, so a two-minute drill gets the same room as any other fourteen snaps. This game is final.
