Four teams join the top 25 this week, headed by the return of Gonzaga at No. 22. Utah State also returns at No. 23 and Florida moves in at No. 24.

Rounding out the list at No. 25 is the season debut of American Athletic Conference leader South Florida. It is the first ever ranking for the Bulls in the coaches poll, though they did receive votes in the 2011-12 season, the last time they made the NCAA tournament.

It was a good week at the top for the Big 12, but a rough one near the bottom of the rankings as three league members fall out. Brigham Young, Texas Tech and TCU all exit the Top 25 along with Colorado State.
