Much of this looks the same heading into Week 6:
1. Boise State (4-0). The No. 4 Broncos dominated New Mexico State in a 59-0 win but still slipped in the national polls after Oregon beat Stanford. They are still the best non-AQ team out there.
2. TCU (5-0). The Horned Frogs have been less than impressive in back-to-back games. The latest was a 27-0 win over Colorado State in which they had a 6-0 lead at the half.
3. Utah (4-0). The Utes were off but still managed to move up to No. 10 in the rankings after other teams lost ahead of them. They have a big game this Saturday at Iowa State, coming off a win over Texas Tech.
4. Nevada (5-0). The Wolf Pack continued their best start since moving to FBS in 1992 with a 44-26 win over in-state rival UNLV. They have now won a series record six straight against the Rebels. The win, combined with other losses, moved them up to No. 21 in the AP poll.
5. Air Force (4-1). The Falcons beat Navy for the first time since 2002, winning 14-6 in a defensive struggle. Their only loss came on the road at Oklahoma. They moved into the AP Top 25 this week at No. 25.
6. Temple (4-1). The Owls erased a 15-point second-half deficit to rally and beat Army 42-35 behind Matt Brown, who had 226 yards rushing. They have a huge game this week at conference foe Northern Illinois.
7. Fresno State (3-1). The Bulldogs only led 21-17 over FCS Cal Poly at the half before pulling away 38-17. Injuries have started to really hurt the team. Running back A.J. Ellis is out for an extended period with a foot injury and the receiving corps also has been hit hard.
8. San Diego State (3-1). The Aztecs had a bye and have extra time to prepare for a big conference game at BYU, which is reeling after losing for the first time in 11 games to Utah State to drop to 1-4.
9. Southern Miss (4-1). The Golden Eagles dominated Marshall 41-16, holding the Thundering Herd to 180 yards of offense, the lowest total of any opponent in the two-plus seasons since Larry Fedora became coach.
10. Northern Illinois (3-2). The Huskies have beaten a team from an automatic qualifying conference (Minnesota) and came close to upsetting another (Illinois). They have won two straight road games and now get Temple at home.
Dropped out: Navy.
