Other models what FPI, SP+ and Elo say about this game, beside Atlas and the market
| Model | Margin | Win | As of |
|---|---|---|---|
| FPI (ESPN) | SEA by 1.3 | 55% | Oct 29 |
| Atlas | SEA by 4.3 | 63% | live |
| Market | SEA by 3.0 | — | live |
Each model's number for this game as its source published it before kickoff; Win is the favored side's chance to win, where the model gives one. FPI's margin and chance are ESPN's own. SP+ is the difference in the two teams' ratings, plus 2.5 for a home side; Elo is the difference in ratings at 24 points a point, plus 2.6 for a home side, as Atlas measured it on past seasons. None of these is an input to Atlas's number, and none is here to settle anything: they show where Atlas sits among other models.
How this grade was computed the four things that set the letter, out of a hundred
Solid card
A moderate disagreement in a band where the model's claim and its realized accuracy stay reasonably close.
Atlas sits 1.3 points from the market. The calibration curve, fitted to every completed season out of sample, expects cards at that distance to fall 8.9% short of what they claim — which is where the calibration component above comes from.
The total has moved 1.5 points since it opened. Cards on a market that has moved have calibrated worse in five of six seasons.
The grade describes how much weight the information deserves. It says nothing about which side of a market anyone should take, and Atlas does not publish that. How grades are computed.
All drivers all 4 things the model is reading, and how each team ranks against the rest of the country
A combined 123 plays per game — the 91st percentile of this season's games. A fast game, which lifts the projected total.
Atlas rates Seahawks' defense at +4.2 points a game against the NFL average and Bears' at +0.8, opponent-adjusted, after 7 games this season.
Playing at home is worth 1.2 points in this season's model, fitted, not assumed.
Bears' offense sits in the 78th percentile of FBS on opponent-adjusted EPA; Seahawks' is 49th percentile.

Two findings that are not in conflict
Atlas has measured disagreement twice, against two different reference points, and they say different things.
| Measured against | What it predicts |
|---|---|
| The closing number | the model's own failure — so a large difference lowers the grade |
| The opening number | which way the line moves — tracked publicly, not graded |
A model far from the close is wrong; a model far from the open is early. The second finding is tracked in the open closing-line record and is deliberately kept out of the grade.
