It has happened this century.
It looks much more possible today than it seemed on October 25th.
In conference, OU has played the 10th, 9th, 8th, 6th ranked defenses in the B12. (Nationally 110, 106, 86, & 83.)
K-State was the first top half B12 defense they've played in conference at #2 (35th nationally).
Out of conference, they've played the 97th & 114th best scoring defenses.
They have #1, #3, #5, and #7 Oklahoma St. left to play. (19, 40, 50, & 86).
Safe to say that the schedule ahead of them should be much tougher than the schedule they've played to date.
