How we got therePoints
Power ratings LV −2.5, KC +3.6: points vs an average team, from every play this season. Each rating point is worth 1.00 points of margin.KC +6.1
Expected TDs LV 2.6, KC 3.0, from Boom TD!'s starters. Each extra expected TD is worth 1.9 points of margin.KC +0.6
Home field home teams won by this much on average over the last five seasons.LV +2.1
Our projected spreadKC +4.7
Projected yards LV 427, KC 522 (Boom Yards). Shown for context, not in the formula: next to the ratings and TDs, yards added nothing in testing.—

We're within a point of the line: the plays, the TDs and the market all tell the same story.

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

If he scores…

  • Kenneth Walker III scores → KC covers 60% (vs 42% when their RB doesn't)
  • Ashton Jeanty scores → LV covers 60% (vs 42% when their RB doesn't)
  • Patrick Mahomes throws 2+ TDs → the over hits 68% (vs 34%)
  • Kirk Cousins 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.
