NCAA Football: Texas Christian at Houston

Just one week ago, Boston College stood in pole position as the Power Five team most likely to join Virginia in the Bottom 25 rankings. The Eagles were coming off a season-opening loss to Northern Illinois and had nearly dropped a home game against FCS foe Holy Cross in Week 2 as they welcomed No. 3 Florida State to town.

BC was a four-touchdown underdog but nearly pulled the biggest stunner of the season so far before falling 31-29 to the Seminoles. With their impressive showing in defeat, the Eagles managed to avoid making their Bottom 25 debut this week. Still, the ranking does feature a new face from the Power Five.

Houston, playing its first season in the Big 12, cracks the ranking at No. 23 after a 36-13 home loss against TCU. The Horned Frogs more than doubled up the Cougars in total yards and nearly tripled them in total first downs while waltzing to a dominant victory. It was a rude welcome to life in the Big 12 for Houston and a sign that this program is not positioned for early success in a more difficult league.

Of course, the warning signs were already there in a 43-41 at Rice, but the lackluster performance against TCU suggested that fifth-year coach Dana Holgorsen's squad may be the worst of the league's four first-year schools.

Bottom 25 rankings

After years as the QB1 of the Bottom 25, Tom Fornelli has passed the baton to David Cobb this season. We're still using Fornelli's power rankings to determine the order -- with the No. 1 ranking belonging to the worst FBS team -- but the written jabs are from Cobb.
