LOUISVILLE, Ky. -- For the first time this season, the USA Today/NFCA Division I poll has a unanimous top-ranked team, as Oklahoma (22-1) took advantage of a 1-3 week by previous No. 1 Alabama (23-3) to ascend to the top position for the first time in 2013.

The Sooners went 4-0 during the past week, with a pair of run-rule victories against Northern Colorado and Drake.
