Boise State moves down a spot to the third spot this week. The Broncos move down despite defeating San Diego State on the road this week. Tulane also moves down a spot this week to the #4 position. Like Boise State, the Green Wave also move down despite a victory this week as Tulane defeated FCS Nicholls State easily at home.

Fresno State rounds out the top 5 and joins Air Force as the two remaining undefeated teams in the Top 5. The Bulldogs finished their out-of-conference play with an easy win over Kent State at home. The Falcons and Bulldogs are currently two of just six remaining undefeated G5 squads.
