What a College Basketball Point Spread Actually Means
A point spread is a handicap set by oddsmakers to level the playing field between two teams. If Duke is listed at -8.5 against North Carolina, Duke has to win by 9 or more for a spread bet on them to cash. Back the Tar Heels at +8.5 and they just need to keep it within 8 points — or win outright.
The half-point eliminates a push, which is what makes the .5 line so common in college ball. Lines open days before tip-off and shift based on where the money lands, injury news, and weather for neutral-site games. Watching that movement tells you as much as the final number does.
