However, Louisiana, Oklahoma State and Houston all dropped significantly after a very trying week.Louisville slipped from the No. 2 spot after they lost their series against Ole Miss in Oxford, which also allowed the Rebels to move up nine spots in the rankings after making their Top 25 debut a week ago.
