NFL key numbers are the final margins of victory that NFL games land on most often. From 2015 through 2025, 14.8% of NFL games were decided by exactly 3 points and 8.7% by exactly 7 — far more than any other margin. That is why a point spread moving across 3 or 7 changes a bet’s value much more than a move between 4.5 and 5.5.

Why 3 and 7 are the key numbers in NFL betting
Most NFL scoring comes in field goals (3 points) and touchdowns with an extra point (7). Close games are often decided by one score, so the final margin clusters on those values and their combinations: 6, 10 and 14 are the next most common.
How the 2015 extra-point change moved the numbers
In 2015 the NFL moved the extra-point snap back to the 15-yard line, making the kick less automatic (NFL.com). Comparing the two periods in the table:
- 7 dipped from 9.3% to 8.7% and 10 from 6.0% to 4.8%.
- 6 rose from 5.4% to 6.9%, and 1 and 2 both became more common.
- 3 stayed the single most common margin in both periods.
What a half point is worth around 3 and 7
A half point only matters when the game lands exactly on the number. Around 3, that happens often:
- The favorite won by exactly 3 in 8.6% of all games since 2015 (261 of 3,024 games with a closing spread).
- When the closing spread was exactly 3, the favorite won by exactly 3 — a push — in 10.2% of those games (44 of 433).
- So −2.5 wins, −3 pushes and −3.5 loses in roughly one game in ten near that line. The same half point between 4.5 and 5.5 changes far fewer results.
How to use key numbers when you compare lines
- Pay the most attention to spreads that sit on or next to 3 and 7.
- Compare the spread and the price together: a better number at a worse price is not automatically better.
- Track whether you beat the closing number over time with closing-line value (CLV).
