There are 41 undefeated Power Four football teams with at least two wins. The Big Ten has the most undefeated teams with 14, followed by the SEC with 12, the ACC with eight, and the Big 12 with seven. TCU's 1-0 record is not included in the Big 12's seven. Human polls love undefeated teams, but wins against inferior opponents sometimes suggest strength that is not real.

In the current AP Poll, Penn State is ranked No.
