NEW YORK — Missouri is No. 1 in The Associated Press Top 25 for the second time in history. Oklahoma is ranked No. 9 in the poll. Missouri became the fourth team this season — joining Southern California, LSU and Ohio State — to hold the top ranking, a day after beating Kansas 36-28 to earn a spot in the Big 12 championship game. Not since 1997 have so many teams been No. 1 in a season. The Tigers' only other time at No. 1 lasted a week in 1960. West Virginia moved up to No. 2 on Sunday, its highest ranking ever, and became the eighth team this season to be ranked second. The Mountaineers' 66-21 victory over Connecticut earned them the Big East title and knocked the Huskies out of the rankings. No. 3 Ohio State, Georgia and LSU complete the top five. This most unpredictable season took another tumultuous turn when Nos. 1 and 2 lost in the same weekend for the second time in two months.
