1972 Cotton Bowl Classic

[1][2] The Texas Longhorns repeated as Southwest Conference champions and were ranked third in the polls in early October, but consecutive losses (to rival Oklahoma in the Cotton Bowl and to #15 Arkansas in Little Rock) dropped them to 3–2 and out of national title contention.

The independent Nittany Lions had climbed to 10–0 and fifth in the rankings before the last game of the regular season, a 31–11 upset loss at #12 Tennessee on December 4.

[3][4][5] (That loss left only Nebraska, Alabama, and Michigan as undefeated, and the first two met for the national title in the Orange Bowl in Miami.)

The teams traded field goals and Texas led 6–3 at halftime, but the Nittany Lions scored 27 unanswered points in the second half.

The convincing win pushed Penn State back up to fifth for the final AP poll, while Texas fell to 18th.
