How the game was won
The model and the market were 10.5 win-probability points apart on the average play, and 21 apart at the widest — with the model the more convinced about Patriots.

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.

How the points landed
The margin ledger
Ezekiel Elliott's 11-yard touchdown catch with 11:18 left in the 1st put New England Patriots ahead for good. The lead never changed over the 5 scores that followed.
Patriots ahead 4–2 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, ±0.37 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.
NE's play-action rate turned over: 30.3% in week 13 against 12.5% here — they faked the run then and dropped back clean now, a turn of 2.3 of their own weekly swings across the two.
32 dropbacks this game, floor 12 — 17 of their games behind the ruler, and their own week-to-week swing is 7.6 points.

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.

NotePIT's sack or hit rate was the night's one real departure: 6.3%, 9.7 points below their season mean of 15.9% and 2.0 times their own 4.9-point weekly swing.
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.
3 players played under 8 snaps, so their shares read as a dash rather than a number. 2 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 Steelers attack right, the Patriots 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.
