1. QB battle: For the first time in six years, the Sooners will have a quarterback derby. Veteran Blake Bell could quash the competition quickly with a dominant spring. But if he sputters operating the base offense or struggles with his accuracy, that could open the door for Trevor Knight or even Kendal Thompson to gain an edge in the contest heading into the fall.
