Big 12 media days have arrived, which means the start of the season is around the corner. Here are five storylines to follow over the next two days in Frisco, Texas:
1. Rookie Red River coaches
Not since 1947 have Oklahoma and Texas had first-year head coaches in the same season. Blair Cherry got the best of Bud Wilkinson that year. But Wilkinson's Sooners won the next three matchups, and Cherry resigned amid criticism, despite going 9-2 in his final season. With the retired Bob Stoops no longer roaming the Oklahoma sideline, the pressure will be ratcheted up in this rivalry.
