Texas went 30-2-1 in Worster’s three campaigns, including a school-record 30-game winning streak that was halted with a 24-11 loss to Joe Theismann-led Notre Dame in the Cotton Bowl on Jan. 1, 1971.

The Longhorns were consensus national champions in 1969 and UPI national champions in 1970.

Worster was a second-team All-American in 1969 when he rushed for 649 yards and nine touchdowns. In 1968, as a sophomore, he rushed for 806 yards and 13 scores.
