OU will go into 2013 without its record-setting quarterback, two of its best receivers and several of its best defenders off a defense that was a disaster anyway the second half of the season. The schedule will be unforgiving, as well.
In the Sooners' losses to Kansas State and Notre Dame, OU scored touchdowns on just three of nine red zone possessions (33.3 percent). In its five wins, it scored touchdowns on 23 of 28 red zone possessions (82.1 percent).
Since the Red River Rivalry has involved Mack Brown and Bob Stoops, the team with the most rushing yards has almost always won. That could be a problem for Texas, which is ninth in rushing defense in the Big 12.
