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 10.9 win-probability points apart on the average play, and 17 apart at the widest — with the model the more convinced about Lions.

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, ±0.37 points.

Neither side “wins” volume or play-calling mix, so neither is drawn as a duel: Bears ran 66 snaps at a 65% dropback rate against Lions’s 45 at 58%. Red-zone trips: Bears 3, Lions 2.

The Read
6 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.
Nothing cleared the bars. No reading led the week's slate, set a season mark, reversed the week before, or sat two of the team's own standard deviations off their number — which is what most Sundays look like, and is the finding rather than a gap.

Was this normal for them?
6 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.

NoteNothing either side did tonight left its own normal range. The widest departure was DET's pass rate over expected, -2.0 pts against a season mean of -5.5 pts — and DET swings 7.8 points week to week, so that is a Sunday, not a plan.

3 players played under 8 snaps, so their shares read as a dash rather than a number. 3 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 Lions attack right, the Bears 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.

6 of 20 drives ended in points. The longest march was DET moving 79 yards from the DET 21 for a touchdown. Each bar is the ground a drive actually covered; DET attacks right, CHI attacks left. Hatching marks a trip inside the twenty.

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.
