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 5.9 win-probability points apart on the average play, and 16 apart at the widest — with the model the more convinced about Jaguars.

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
Brandon Aiyuk's 13-yard touchdown catch with 11:42 left in the 1st put San Francisco 49ers ahead for good. The lead never changed over the 6 scores that followed.
49ers ahead 9–0 on categories, including the biggest gap of the duel — red-zone touchdowns.
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, ±0.60 points.

Neither side “wins” volume or play-calling mix, so neither is drawn as a duel: 49ers ran 57 snaps at a 53% dropback rate against Jaguars’s 54 at 72%. Red-zone trips: 49ers 7, Jaguars 2.
Note49ers won the down-to-down efficiency fight: 0.32 expected points added per play vs -0.47.

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.
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?
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.

4 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 Jaguars attack right, the 49ers 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.
