Grading the Sooners' 62-21 victory over Missouri: Depth: A Linebacker Austin Box and tailback DeMarco Murray (after the opening kickoff) missed the game, but OU reserves Mossis Madu, Quinton Carter and Mike Balogun played well. South reputation: B The South Division won its fifth straight Big 12 title (four by OU, one by Texas), but Missouri became the first North team to score more than one touchdown in the Big 12 title game since Kansas State in 2003. The North had combined for just two touchdowns the previous four Big 12 title games. Sportsmanship: D Sam Bradford in the game late, throwing deep with a 54-21 lead? I know bad blood brewed all night between these teams, but OU didn't need that kind of style points. OU fans: A Another trip to Kansas City, another great turnout by the Sooner swarm, estimated at 20,000. Juaquin Iglesias: A The smooth flanker had nine catches for 125 yards and two touchdowns, including six catches for third-down conversions. Maclin Containment: B The Sooners did not let Mizzou speedster Jeremy Maclin get free; seven catches for 46 yards; one carry for two yards and seven kickoff returns for 132 yards, with a long of 30 yards.
