A key number in sports betting refers to the most common margin of victory or total points scored in a particular sport. These numbers often have a significant impact on the outcome of a game and are important for bettors to consider when placing bets. For example, in football, the most common key numbers for the point spread are 3 and 7, as many games are decided by a field goal (3 points) or a touchdown and extra point (7 points). In basketball, key numbers for the point spread are 3, 7, and 10. Understanding key numbers can help bettors make more informed decisions when placing bets, as they can consider how the odds may be affected by these numbers.
