A moderate disagreement of 2.6 points.
Across seven seasons, cards this far from the market claimed 59% accuracy and delivered 50%. That gap is where this grade comes from.
How much weight this card's information deserves — not a recommendation.

- One book is quoting this game, so the market number has no depth behind it and may move sharply.
- Atlas and the market have moved opposite ways on the total since it opened.

Other models what FPI, SP+ and Elo say about this game, beside Atlas and the market
| Model | Margin | Win | As of |
|---|---|---|---|
| FPI (ESPN) | DET by 1.4 | 55% | Oct 29 |
| Atlas | DET by 0.4 | 51% | live |
| Market | DET 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
Mixed card
The disagreement is wide enough that the model's historical claim runs well ahead of what it delivered.
Atlas sits 2.6 points from the market. The calibration curve, fitted to every completed season out of sample, expects cards at that distance to fall 11.9% 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
Atlas rates Vikings' defense at +5.7 points a game against the NFL average and Lions' at -1.9, opponent-adjusted, after 6 games this season.
Atlas rates Lions' offense, with its expected quarterback, at +5.3 points a game against the NFL average and Vikings' at -1.5, opponent-adjusted, after 6 games this season.
A combined 115 plays per game — the 55th percentile of this season's games. A middling number of possessions either way.
Lions' offense sits in the 75th percentile of FBS on opponent-adjusted EPA; Vikings' is 9th percentile.
Market movement how far the market has moved since the number opened, and which way
Total, open to current
| Measure | Value |
|---|---|
| Opening number | 47.5 |
| Current number | 46.5 |
| Market direction | down 1.0 |
| Atlas direction | up |
Atlas and the market point opposite ways on this total. That is information, not a verdict.
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.
