Why

what the model is reading

Be careful about

  • 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.

How this number is made. Every FBS team starts the season at a preseason expectation built from last season's ratings, roster talent, recruiting, returning production and the coaching situation. After every game a filter updates each team's offense and defense, opponent-adjusted, and the two teams' numbers meet here with the home advantage. The total adds the teams' pace and the wind. The market is never an input; it is shown so you can see where Atlas differs and read why.

A difference is not an edge. Atlas has measured what happens at every size of disagreement, and the gap between what the model claims and what it delivers widens as the disagreement grows. This game sits in the 0-1 band, where cards have claimed 53% accuracy and delivered 53% across 541 games.

Figures come from completed games only, so every one was known before kickoff. They are raw, not adjusted for opponents - All drivers has Atlas's adjusted view. Passing yards are net of sack yardage, as the NFL counts them.

ModelMarginWinAs of
FPI (ESPN)BUF by 2.961%Oct 29
AtlasBUF by 4.062%live
MarketBUF 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
A91

High-reliability card

Atlas and the market agree closely, and this disagreement band has been among the model's most consistent across seven seasons.

Calibration 38/45
Market agreement 23/25
Card conditions 15/15
Data completeness 15/15

Atlas sits 1.0 points from the market. The calibration curve, fitted to every completed season out of sample, expects cards at that distance to fall 5.7% short of what they claim — which is where the calibration component above comes from.

The season is mature enough for the team profiles to have settled, and the market has not moved much since it opened.

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
Pace and possessions 116 plays · 65th percentile

A combined 116 plays per game — the 65th percentile of this season's games. A fast game, which lifts the projected total.

Two findings that are not in conflict

Atlas has measured disagreement twice, against two different reference points, and they say different things.

Measured againstWhat it predicts
The closing numberthe model's own failure — so a large difference lowers the grade
The opening numberwhich 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.

Read the gap, not the claim. Atlas's raw confidence numbers run high — a claimed 53% has historically delivered 53%. The grade already corrects for this. The claim is shown so the correction is visible rather than hidden.
What this card is. Research, analytics and market context. Atlas does not publish selections, does not size anything and does not project returns. Every figure is computed out of sample from a point-in-time database: nothing attached to a game uses information that did not exist before kickoff.
