Conference play is Rubypointin full swing in men’s college basketball, and those results are sure to produce plenty of fluctuation in the USA TODAY Sports Coaches Poll the rest of the way.

The changes didn’t reach the top this week, however, as Purdue retains the No. 1 position. The Boilermakers handled their top-10 showdown with Illinois this week and retain 21 of 32 first-place votes to stay on top of the rankings.

Houston, one of the few remaining teams still unscathed, nudges ahead of new Big 12 rival Kansas for the No. 2 spot. The Cougars claim 10 first-place nods this week, with the Jayhawks holding on to the last one.
