We continue ranking the top-5 players at every position in Big 12 history. Next up, we take a look at the defensive backs:
1. Roy Williams, Oklahoma (1998-01): He’ll forever be a Big 12 icon for his “Superman” leap against Texas in 2001, but that’s just where his OU legacy begins. Williams set the standard for Big 12 defensive backs in 2001. He won the Bronko Nagurski Trophy as the nation’s best defensive player, was Big 12 Defensive Player of the Year, took home the Thorpe Award and even finished seventh in Heisman voting.
