An unhinged weekend that saw the majority of conference play kick off across the country did not disappoint, as three of the final unbeaten teams in college basketball fell on Saturday — including Villanova, the No.1 team in last week's AP Top 25 poll.

As a result, the top of the rankings is a mired mess with a makeover and a new name at the top.

Welcome to the No. 1 spot, Sparty!

Michigan State (14-1) began the season 1-1 but hasn't lost since, steadily idling in the top 5 all season before pouncing in the middle of the madness this weekend. The Spartans face a hobbled Maryland team iThursday as they look to defend their spot atop the standings.

Behind Michigan State is Duke (13-1). Villanova and Arizona State each fell to No. 3 and N. 4, respectively, after watching their unblemished records slip away this weekend. Rounding out the top five is Xavier, which moved up one spot from last week.
