There were four newcomers to the rankings this week: No. 20 Wisconsin, No. 22 Memphis, No. 24 Colorado State and No. 25 Kentucky. Wisconsin, Memphis and Kentucky, the defending national champion, were all ranked early in the season, while Colorado State makes it first appearance in the poll since March 9, 1954. They replace Creighton, Cincinnati, Minnesota and Missouri, the only one of the four not to lose two games last week.
