How we got therePoints
Power ratings SEA +5.4, LAC −1.5: points vs an average team, from every play this season. Each rating point is worth 1.00 points of margin.SEA +6.9
Expected TDs SEA 2.7, LAC 1.9, from Boom TD!'s starters. Each extra expected TD is worth 1.9 points of margin.SEA +1.6
Home field home teams won by this much on average over the last five seasons.SEA +2.1
Our projected spreadSEA +10.5
Projected yards SEA 468, LAC 360 (Boom Yards). Shown for context, not in the formula: next to the ratings and TDs, yards added nothing in testing.—

We're 3.5 points more on SEA than the line. The biggest reason is the power ratings (SEA #2 on the field but #3 in the market; LAC #22 vs #14). 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 3–6 points, our side covered 44% of the time (399 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 319 games it never saw (2025–2026), the line was closer to the final margin 60% of the time, and betting our number against it won only 43%. The full record

Every NFL regular-season game 2006–2026 where the favorite laid 6.5 to 7.5 points (as close to 7 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.

If he scores…

  • Omarion Hampton scores → LAC covers 60% (vs 42% when their RB doesn't)
  • Jadarian Price scores → SEA covers 60% (vs 42% when their RB doesn't)
  • Justin Herbert throws 2+ TDs → the over hits 68% (vs 34%)
  • Sam Darnold 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.
