Yet another crazy week, especially in the Big 12, as Kansas, Baylor and West Virginia all lost to unranked teams at home on Saturday. Eight of the top 15 in last week's Power Rankings went down at least once, and Baylor and Notre Dame both lost twice in the past week.
Oregon made a huge statement by blasting Arizona in Eugene. Florida did the same with a shellacking of Kentucky -- and Purdue re-entered the poll after a one-week hiatus following wins over Northwestern and Maryland.
