Why 1985 mattered

In 1985, the NCAA standardized the field at 64 teams, which locked in the four-region bracket of 16 teams per region that made office pools and bracket predictions explode in popularity. This structure created more room for underdogs, setting the stage for the “Cinderella” runs that are now a huge part of March Madness culture.
