Market vs Snaps
The closing line is the sharpest public opinion in football. The snaps are what actually happened on the field. Across 136 games they agreed on who should cover 111 times; on average the snaps landed 8.8 points away from the line. These are the teams the market keeps misreading. Analysis, not advice: we make no picks here.
↳Bottom lineAcross 136 games the snaps landed 8.8 points from the line on average. Biggest gaps: Jaguars (+8.3) and Eagles (−8.9). This describes the season; it is not a betting signal.
?How to read this chart
- One logo = one team.
- Left to right: how many points a game the betting line expected the team to win or lose by, on average (the market). Bottom to top: how many points a game its play on the field was actually worth (the snaps, from expected points: how much each play moved the expected score).
- The diagonal line
- is where the two agree. A logo above it (green zone) played better than it was priced; below it (red zone), the market priced it higher than its play.
- The short stem
- under or over each logo shows the size of that gap. Farther from the line = bigger disagreement.
The market gap, team by team
?How to read this chart
- Gap
- is points a game the team's play beat (green, to the right) or trailed (red, to the left) the betting line. The middle of the bar is zero.
- Against the line
- is the real record against the spread: wins, losses, ties. The next column is the same count if the final score had matched the play on the field.
- Trend
- is the gap week by week: above the faint middle line = better than priced, below = worse.
Where they disagreed most
?How to read this chart
- Each card is one game.
- Market: the team the betting line favored and by how much. Snaps: the team that played better and by how much. Gap: the difference in points.
- The strip under each card
- places three dots on one scale, all from the home team's side (right of the center tick = home team ahead): white = the betting line, green = the snaps, small amber = the final score. Dots far apart = the game the line expected is not the game that was played.
line snaps final score, all as the home team's margin.
How sure are we? Across 27 seasons the gap between the snaps and the closing line did not predict covers later in the season. The tool describes a season; it is not a betting signal. The test →
MethodHow this is built
- The market
- The closing point spread from nflverse, as the home team's expected margin. A team's market rating is its average expected margin across its games.
- The snaps
- The deserved margin from The Verdict: what each side's net EPA per scrimmage snap is worth in points, with fumble bounces evened out.
- The gap
- Deserved margin minus the line, from the team's side, averaged. Positive: the team played better than the market priced it. The trend line is the running average week by week.
- Against the line
- Real results against the spread (wins, losses, pushes), next to the same count using the deserved margin instead of the final score.
- Not advice
- Everything here looks backwards. A gap can close because the market adjusts, because the team changes, or by chance.
