With spring ball now a month away, we're ranking position groups in the Big 12 over the next two weeks. These evaluations will be based on past performance, future potential and quality depth of the entire group. Our outlooks will look different after the spring. But this is how we see them at the moment.
We begin this series with the quarterbacks:
1. Oklahoma: Baker Mayfield might be the top returning quarterback in college football. He's twice finished in the top five of the Heisman Trophy voting and broke the FBS passing efficiency season record last season.
