Only two active quarterbacks can say they've defeated Alabama: Ole Miss' Chad Kelly and Texas A&M's Trevor Knight.
The latter faces the Crimson Tide for the second time in his career and the first time since Jan. 3, 2014, when Knight -- then a redshirt freshman -- led Oklahoma to a 45-31 Sugar Bowl win over Alabama.
Much has changed since then: Knight is now a fifth-year senior, he no longer plays for the Sooners and most Crimson Tide players on the field that day are no longer on the roster.
