What the NBA Point Spread Actually Means
When you see the Lakers listed at -7.5, that means they need to win by eight or more for a spread bet on them to cash. The underdog, listed at +7.5, covers if they win outright or lose by seven or fewer. The half-point — called the hook — eliminates any chance of a push, meaning every ticket resolves as a win
or a loss. Oddsmakers set the opening line based on team strength, rest days, travel and injury reports, then the line shifts as money comes in from across eligible states. Watching that movement tells you where sharp action is landing before tip-off.
