The Weekly Line Cycle
Look-ahead lines open Sunday night, sharpest money arrives early week, and public money floods Friday through kickoff — typically inflating favorites and overs. Injury reports (Wednesday-Friday practice designations) drive the biggest mid-week moves; QB news moves lines 4-7 points, more than any other position.
Key Numbers Rule Everything
Field goals decide NFL games: margins of 3 (most common) and 7 dominate outcomes. Crossing 3 — say +2.5 to +3.5 — changes win probability more than any equivalent half-point elsewhere. Never lay -3.5 or take +2.5 without shopping for the number across books first.
Beyond the Main Lines
Player props (yardage, receptions) are softer than sides — books can't sharpen hundreds nightly. Derivative markets (team totals, first-half lines) sometimes lag main-line moves. Live NFL betting rewards those who understand situational football: script changes after turnovers and injuries take moments for models to fully digest.
