What are key numbers in NFL betting? | Who Wins on Sunday?

Key numbers are margins of victory that occur relatively often because of football scoring. Three and seven are especially recognizable because field goals are worth three points and touchdowns plus extra points commonly produce seven.

What to remember

Crossing a key number can materially change the meaning of a spread. That is why -2.5 versus -3.5 is more significant than the one-point difference might first appear.
