Eleven of those 14 unbeaten seasons have been “perfect” in the sense that no games ended in a tie.
The seasons in which the Sooners went undefeated have ranged from two-game seasons, which was the norm back in the late 1800s before the turn of the century, to a 13-game schedule, which was the case the last time Oklahoma recorded an undefeated, untied season, in 2000.
In the Bud Wilkinson years, from 1947 to 1963, Oklahoma went undefeated four times, including three years in succession (1954-56, during the Sooners’ epic 47-game winning streak). All four were perfect seasons.
