Detroit Lions 42, Seahawks 29 — with the result never quite settled.
It turned at Q1 1:06, 1st and 10, on DK Metcalf — 13.6 win-probability points to the Lions on one snap, the largest move of the game.

How the game was won
The model and the market were 2.6 win-probability points apart on the average play, and 9 apart at the widest — with the model the more convinced about Seahawks.

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.

The read
Lions ahead 4–3 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, ±0.89 points.

Neither side “wins” volume or play-calling mix, so neither is drawn as a duel: Seahawks ran 79 snaps at a 80% dropback rate against Lions’s 48 at 46%. Red-zone trips: Seahawks 6, Lions 5.

The Read
11 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.
highest in the league that weekAgainst the weekTendencies
SEA's early-down pass rate, 77.3%, was the highest of the 32 team-games charted in week 4 — 5.6 points clear of the next team along.
66 early downs this game, floor 15 — 17 of their games behind the ruler, and their own week-to-week swing is 12.4 points.
DET's pass rate over expected turned over: −14.3 pts in week 3 against −2.4 pts here — they ran more than the situation asked then and threw more than the situation asked now, a turn of 2.1 of their own weekly swings across the two.
48 snaps this game, floor 20 — 17 of their games behind the ruler, and their own week-to-week swing is 5.8 points.

Was this normal for them?
11 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.

5 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 Seahawks 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.
