Negative = favorite, Positive = underdog

How Point Spreads Work

A point spread levels the playing field between two unevenly matched teams. The favorite gets a negative spread (must win by more than that number) while the underdog gets a positive spread (can lose by up to that number and still "cover").

Key numbers in football: 3 and 7 are the most common margins of victory. Spreads crossing these numbers are significant.
