The Number.
Negative means Seahawks is favored. Your number is the spread you think is right; leave it blank to see the market on its own.
Break-even at -110 is 52.4%. The market's number is right on average, so you need about a point of real edge before −110 pays.
6,999 regular-season games, 1999–2026, from nflverse. For the number you enter, the model takes every game that closed at that spread and reads off what actually happened — so the piles on 3 and 7 are real, not assumed. Win probability also shows the classic normal model (σ = 13.2 points).

Six-point teaser
Move this side six points in its favor. Worth it when it crosses both 3 and 7 and the price is right; at −120 for two legs you need each leg to hit about 74%.
A two-leg teaser at −120 breaks even when both legs hit 74% of the time; at −110 it's 72%. Legs that cross 3 and 7 — favorites of 7.5 to 8.5 and underdogs of 1.5 to 2.5 — are the classic candidates.
