the line
We're 2.7 points more on ARI than the line. The biggest reason is the power ratings (ARI #25 on the field, #24 in the market; DET #13 vs #9). The market prices things our formula doesn't see: injuries, matchups, weather, last season, and the sharpest money in the world.
Is a gap this big an opportunity? When we've disagreed with the line by 0–3 points, our side covered 49% of the time (1410 games, 2019–2026). You need 52.4% to break even at −110. The line has been the better bet.
For your bet: This number explains the game; it isn't a bet against the line. Tested on 336 games it never saw (2025–2026), the line was closer to the final margin 59% of the time, and betting our number against it won only 44%. The full record

Show the 545 games behind these numbers
Every NFL regular-season game 2006–2026 where the favorite laid 4 to 5 points (as close to 4.5 as gives at least 300 games), and how it finished. Each bar is how many games the favorite won by that margin; below zero, the underdog won.
- Chance: the share of those games. “DET by 7+” = games won by 7 or more ÷ all 545.
- Fair odds: the price with no bookmaker cut, where you'd break even over time. 50% is +100; 25% is +300; 75% is −300. Pushes are set aside.
- Key numbers (outlined): 3 and 7 are the most common margins, a field goal and a touchdown.
- Checked: we re-test this on every update. See how close it's been.

Fair price −106 · at −110 it's about fair
Pick the bet your book offers and type its price. Win, push and lose are the share of the same past games. Value is the chance of winning × what you'd win, minus the chance of losing × your stake; within 2¢ per $1 we call it fair.
Total ladder
For your bet: Totals have no big key numbers: no single final total happens much more than 4% of the time. Don't pay extra juice to move a total by half a point.
Show the 2,707 games behind these numbers
Every NFL regular-season game 2006–2026 with a half-point total, and how far the final score landed from its posted total. Shown here as if the total had been 54.5. Totals move with the era, so the line itself sets the middle, and history sets the spread around it.
Touchdowns move this game
If he scores…
- Jahmyr Gibbs scores → DET covers 60% (vs 42% when their RB doesn't)
- Jeremiyah Love scores → ARI covers 60% (vs 42% when their RB doesn't)
- Jared Goff throws 2+ TDs → the over hits 68% (vs 34%)
- Jacoby Brissett throws 2+ TDs → the over hits 68% (vs 34%)
These are averages for every starting RB (3,277 games) and QB (3,631 games) 2019–2026, not numbers for these players. The players are this week's likeliest scorers on Boom TD!.
For your bet: These legs move together. An anytime TD plus his team covering hits about 19% more often than the two chances multiplied, so it's a natural same-game parlay. Check the parlay price against that.
