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.

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.
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.
DET's pass rate over expected turned over: −16.4 pts in week 17 against +5.1 pts here — they ran more than the situation asked then and threw more than the situation asked now, a turn of 2.9 of their own weekly swings across the two.
72 snaps this game, floor 20 — 17 of their games behind the ruler, and their own week-to-week swing is 7.5 points. · +1.3σ from their own normal
DET's sack or hit rate turned over: 36.0% in week 17 against 11.1% here — they got home then and stayed blocked now, a turn of 2.8 of their own weekly swings across the two.
36 dropbacks this game, floor 12 — 17 of their games behind the ruler, and their own week-to-week swing is 8.7 points. · −0.6σ from their own normal

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. 6 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 Bears attack right, the Lions 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.
