How games at these numbers have gone

  • The key number. 3.5 sits half a point past 3, one of the margins games actually land on. That hook is most of what you are paying for or getting here.
  • Spread 3.5 — the 3-4 point band. In 1,737 games since 1999 the favorite covered 48.5% of the time — a coin flip once the 95% range (46.2–50.9%) is taken into account.
  • Total 40.5 — spread in the 3-7 point band. Games with a spread this size went over 49.5% of the time across 3,551 of them.

The Read

Seattle Seahawks open a 3.5-point favorite over Arizona Cardinals — about 67% implied to win outright. The 40.5 total prices it near 22–19, a low-scoring script.

Seattle Seahawks went 14–3 in 2025 — #1 of 32 by point differential (+11.2/g).

Arizona Cardinals went 3–14 in 2025 — #29 of 32 by point differential (-7.8/g), and were 2.4 wins unlucky versus their margin.

Arizona Cardinals face one of the NFL's toughest 2026 schedules (strength of schedule #3).
