-- Baylor's stint as the No. 1 team in the country lasted one week -- and in actuality, one day, as the Bears lost Monday in Morgantown. Now it's a close call among the top half-dozen teams in the country, and we'll give Villanova the slight nod after it pounded Xavier.
UCLA, Kansas, Gonzaga, Baylor and Kentucky are all in the mix. Duke had a rough week and tumbled 10 spots. Xavier also fell after losing twice. South Carolina returns to the Power Rankings, and Maryland cracks the top 25.
1. Villanova Wildcats
Last week's ranking: 2
Josh Hart was held to a season-low 11 points and Kris Jenkins missed his first nine shots, but the Wildcats still wound up beating St. John's on Saturday at Madison Square Garden.

Last week's ranking: 4
Bill Self's team has reeled off 16 straight after a loss to Indiana in the season opener in Hawaii.
4. Gonzaga Bulldogs
Last week's ranking: 5
