You can bet Jets +2.5 at one book and Steelers -3.5 at another — same game, six-point price gap. Shop the spread and grab the free six points.
I have three apps open. Book A has Jets +2.5. Book B has Steelers -3.5. I'm taking the free six points and ordering a sandwich.
Seventy-one sportsbooks cannot agree on whether the New York Jets or the Pittsburgh Steelers should be favored. The home spread ranges from Pittsburgh -3.5 to Pittsburgh +2.5. That is a six-point swing across the entire market. Source: game_odds:7bd4a1cf68fa48420e0ea7b5af4d4cc0.
Six Points Free on One Game
Dispersion is the gap between the lowest and highest spread among books posting the game. A dispersion of zero means every book posted the same number. A dispersion of six means the market is still arguing.
The Jets at Steelers game posts a dispersion of 6 across 71 books. Compare that to the rest of the NFL slate the same night:
- Buffalo at Cleveland: -3 across 71 books, dispersion 0. Source:

Every other NFL game on the board shows total or near-total agreement. One game does not. That game is the story.
Why Books Can't Agree
The Jets have a new QB room. They rebuilt the O-line. Their defense was top-five last year. The Steelers return a veteran QB. They have a proven coach. Their home field grades above average. The math models point in opposite directions.
Preseason games added noise. They gave zero signal. The Jets sat starters. The Steelers played theirs. The box scores lied. The books know this. They shade lines to cover their own action. They don't agree on a true number.
Money from winning bettors has moved some books. Others have not moved. Books still disagree.
How to Cash the Gap
You do not pick a side. You shop the spread (check multiple books for the best price).
If you like the Jets, you find the book offering +2.5. If you like the Steelers, you find the book offering -3.5. The same opinion costs six points less at the right window.
This is not line shopping in the abstract. This is line shopping as the entire edge. The spread is the handicap.

Every other game clusters within a field goal or less. The Jets-Steelers gap is two field goals. That is not noise. That is a market that has not finished thinking.
What Kills This Edge
If the Jets spread collapses to a single number across 71 books — or if a starting quarterback injury moves the median by more than a field goal — the dispersion story ends. Until then, the only honest take is that the market has not spoken.
NFL ATS cover-margin distribution
Distribution of (final margin − closing spread) across an NFL season. Roughly normal with mean ≈ 0 and standard deviation ≈ 13 points, which is why most ATS edges live in the ±1.5 point window.
Model calibration: predicted vs observed
Predicted win probability bucket vs the empirical win rate inside that bucket on the test set. Points on the y=x reference line are perfectly calibrated; points below mean the model is overconfident in that bucket.
