The model against the market, the momentum underneath, every drive — scrub to replay it
How the game was won
The model and the market were 7.6 win-probability points apart on the average play, and 28 apart at the widest — with the model the more convinced about Broncos.

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.

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, ±0.35 points.

Neither side “wins” volume or play-calling mix, so neither is drawn as a duel: Broncos ran 57 snaps at a 74% dropback rate against Chiefs’s 63 at 65%. Red-zone trips: Broncos 2, Chiefs 5.

The Read
7 of 8 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 8 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.

KC's sack or hit rate, 23.8%, was the highest of the 32 team-games charted in week 15 — 0.5 points clear of the next team along.

Was this normal for them?
7 of 8 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.

The Game Day Roster
Who was out, who dressed and never took a snap, and who was on the field how much. Game-day list and snap counts from the weekly roster and snap feeds. Practice-squad and injured-reserve players are not shown — they were never on the game-day list.
Snap, route and expected-points data starts in 2021. This game is older than the usage record, so there is no opportunity read for it — the box score above is the complete picture we hold.
The field map
Every snap, where it happened
The whole game as one hundred yards. The Chiefs attack right, the Broncos 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.

Personnel groupings
Offensive grouping on every pass and run. A group needs five snaps in this game before it gets a number — under that the sample is a coin flip and the cell reads a dash instead. The names of the eleven on the field are only recorded from 2023 onward, so this game gives the grouping without the roster.
