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.
