The final Saturday in February turned out to be a historic day in college basketball. Each of the top six teams in the AP Top 25 lost, the first time that has ever happened on a single day in the history of the poll. A total of seven members of the AP top 10 fell, also a single-day record.
What does it mean from a Bracketology perspective? Well, imagine an NFL weekend in which every game ends in a tie. No team would lose or gain an inch in the standings. That's what happened in college basketball on Saturday.
