After back-to-back three-loss seasons, Bob Stoops shook things up by firing three assistants. That, combined with a regime change at quarterback, makes this spring perhaps the most intriguing -- and most critical -- of the Stoops era.
Outside of Damien Williams and Sterling Shepard, few Sooners from the Class of 2012 played a substantial role last season. But this class could still prove to be one of the better ones of the Bob Stoops era.
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).
