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.

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: Chiefs ran 70 snaps at a 63% dropback rate against Ravens’s 56 at 82%. Red-zone trips: Chiefs 3, Ravens 2.
NoteRavens outgained Chiefs 337-322 but lost the turnover battle 3-0. That was the game.

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.
Too few to read
2 of 12 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.
BAL's early-down pass rate, 86.0%, sat 33.7 points above their season number of 52.4% — they passed early by 3.4 times their own 9.8-point weekly swing.
43 early downs this game, floor 15 — 17 of their games behind the ruler, and their own week-to-week swing is 9.8 points. · +3.4σ from their own normal
BAL's pass rate over expected, +13.1 pts, sat 13.6 points above their season number of −0.6 pts — they threw more than the situation asked by 2.5 times their own 5.5-point weekly swing.

The season-grain rooms, pointed at this one game
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.
This is not a regular-season game, so every season number below is that team's 2023 regular season — the only stretch long enough to be a habit.

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.
2 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 Ravens attack right, the Chiefs 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.
