The good vibes in Boulder could not even last a week. After the Colorado Buffaloes picked up their first Big 12 win of the season against Kansas State, they went on the road and laid a dud against Arizona State. It was the Buffs ' fifth Big 12 loss and sixth overall loss of the season.

National power rankings obviously haven't been kind to the Buffs, and that continued this week when USA TODAY Sports' 1-138 re-rank dropped Colorado six spots.

Colorado now ranks No. 97 nationally and is the lowest-ranked Big 12 program. This week, the Buffaloes face Houston, the No. 15 team in the power rankings.

The Buffs have no wiggle room when it comes to bowl eligibility, needing to win out to reach six wins. They face a top-15 opponent this week, followed by a road game at Cincinnati and a home game against UCF. All three opponents have winning records, and the latter two are also fighting for bowl eligibility, both with five wins entering Week 11.

A few other Power Four programs surround Colorado, including Stanford (No. 94), Cal (No. 100), Georgia Tech (No. 102) and Maryland (No. 103). The top 10 changed significantly again, with Georgia taking over the No. 1 spot and Utah moving up to No. 2. Notre Dame, Miami and Indiana round out the top 5

The Big 12 is well represented at the top of the rankings: Utah at No. 2, BYU at No. 12, Houston at No. 15, Texas Tech at No. 17 and Arizona at No. 22.
