Before the Sooners' 31-14 win over Iowa in the Insight Bowl, Jake Trotter and Brandon Chatmon analyzed each Oklahoma position group. Now, the SoonerNation staff is giving each position a grade for its performance in 2011.

Grade: B-
The Big 12 is a tough league to defend, but a No. 55 ranking in total defense is unacceptable at OU. The defense had some phenomenal performances (Florida State, Texas and Kansas State). But it will be remembered for how it fared against Texas Tech (41 points), Baylor (45 points) and Oklahoma State (44 points).
