Here are five storylines to keep an eye on during Week 5 in the Big 12:
Sooners need to rally
Oklahoma’s playoff dreams are probably dead, and for that reason this season might be labeled a disappointment no matter how the Sooners fare in Big 12 play. But they’ve had two weeks to get over the Ohio State loss. They have to get back to playing like the dominant squad that rolled through the Big 12 in 2015. A road game at No. 21 TCU presents a perfect opportunity to make a loud declaration that OU is still a major contender for the Big 12 title.
