No team is going undefeated. After former No. 1 Kansas and Sherron Collins(below) fell to shorthanded Tennessee, only Kentucky and Texas had spotless records through Sunday, but both will lose because they are heavily dependent on freshmen.... Oklahoma is the most disappointing team in the country. Ranked 17th at the start of the season, the Sooners lost by 31 in their Big 12 opener at Baylor last Saturday to fall to 9--6.... Wisconsin's Bo Ryan is a leading candidate for national coach of the year. His team's upset of then--No. 4 Purdue last Saturday was its second over a top 10 team this season. The Badgers (13--3, 3--1 in the Big Ten) have gone from unranked to No. 13.
