This past Saturday featured the craziest, most upside-down day of the men's college basketball season thus far. Eleven AP-ranked teams lost, according to ESPN Stats & Information research, with 10 of them losing to lower-ranked or unranked opponents.
Eight top-15 teams lost, with five losing at home. Three top-10 teams lost -- at home.
And it didn't stop after that, with five top-15 teams also losing between Tuesday and Wednesday.
There were massive changes to the Power Rankings as a result, with Purdue the biggest beneficiary, rising six spots. The Boilermakers have great résumé-based metrics, strong efficiency-based metrics and rank third in the country in Quadrant 1 and 2 wins, behind only Auburn and Alabama.
