Using a teaser bet can be a good strategy compared to a straight point spread bet when the bettor believes that the adjusted point lines will significantly improve their chances of winning, particularly in close matchups or games where teams have similar skill levels. Teasers are especially advantageous in sports like football, where scoring can be more variable, and key numbers (like 3 and 7) play a crucial role in the point spread. If a bettor is confident in the outcomes of multiple games but wants to mitigate risk, a teaser allows them to secure more favorable odds while potentially making otherwise difficult lines easier to cover.
