Upsets are one of the best things about college football from a neutral perspective.
In Week 9, four Top 25 teams fell to unranked foes, and those results could create another rearrangement of the rankings ahead of Week 10.
Oklahoma State lost its inside path to the College Football Playoff through an upset to Texas at home, Michigan lost to a rival on home soil, North Carolina fell on the road for the second time and Kansas State failed to gain ground on Oklahoma State by tripping up on its travels.
The expected drops of those four programs, plus the fall Penn State should take after losing to Ohio State, opens up space for Group of Five teams and upstart Power Five squads to move up in the Week 10 rankings.
