San Diego State 21, No. 19 Boise State 19
So much for Boise State's BCS-busting dreams. The Broncos were well-positioned to earn an at-large berth despite having lost their season opener to Michigan State, but that hope died after a shocking home loss to San Diego State. The Aztecs held off Boise's fourth-quarter rally to win their fifth straight and move into a tie for first place in the conference. Boise has now lost at home two years in a row; San Diego State had not beaten a ranked team since topping Wyoming in 1996.
