Colorado, Duke Climb Into Week 2 AP Top 25 Poll After Historic Upsets

The Colorado Buffaloes and Duke Blue Devils both climbed into the Week 2 Associated Press Top 25 poll following historic upsets in Week 1.

The Buffaloes defeated the reigning Big 12 champion and national champion runner-up TCU Horned Frogs, 45-42, in Pro Football Hall of Famer Deion Sanders' debut as head coach. Duke upset the reigning ACC champion and perennial College Football Playoff contender Clemson Tigers, 28-7, during a primetime matchup on Monday (September 4) night.

Naturally, the Horned Frogs and Tigers saw the biggest fall of any team ranked in the preseason Top 25, with TCU, which had ranked No. 17 overall, falling out of the rankings completely and Clemson dropping 16 spots to No. 25 overall, the only winless team included in the Week 2 Top 25.
