College Football Power Rankings: BYU skyrockets into top three amid latest shakeup after chaotic Week 7

The Big 12 is slowly emerging as a contending power among its peers. Half of the remaining unbeaten FBS teams call the Big 12 home.

BYU lifted spirits with a huge win over Notre Dame, the sport's most recognizable brand, and one-loss Houston picked up an impressive win over giant-killer Oklahoma State. The three remaining undefeated Big 12 teams are slotted in the top 10 of CBS Sports' Power Rankings halfway through the season.

Meanwhile, the Big Ten and SEC keep beating each other to a pulp. Two of their undefeated teams, Indiana and Georgia, fell in Week 7, though Indiana's loss was more "impressive," a 19-15 setback to Ohio State. No. 1 Georgia fell between the hedges to an unranked Auburn squad. The Tigers delivered a historic upset, scoring multiple touchdowns in Athens for the first time in 17 years and securing their first win there in over two decades.

Week 7 was the wildest one yet this fall. Five of the top seven teams in the AP Top 25 lost, the most in the poll's history. BYU controversially held on in the final second to secure a 28-24 win over Notre Dame, the program's biggest win since 1990.
