The Colorado Buffaloes came in as the No. 19 team in the nation in both the Associated Press' top 25 and the USA Today Coaches' Poll for Week 4. Tad Boyle's team moved up from the 23rd spot in last week's AP Poll and entered the top 25 altogether in the USA Today Poll.
The Buffs are now 5-0 on the year after Sunday's 89-74 victory against Air Force. And they're making noise after being ranked by Pac-12 media members as the sixth-best team in the conference, according to a preseason poll.
The Arizona Wildcats, at No. 9, are the only other Pac-12 team in the AP poll. They are ranked similarly in the USA Today Poll, which also has the UCLA Bruins at No. 24 despite their Sunday loss to Cal Poly.
Both polls have, in order, the Indiana Hoosiers, Duke Blue Devils, Michigan Wolverines and Ohio State Buckeyes in first through fourth place.
