Bottom line: Baker Mayfield started his college career as a walk-on at Texas Tech, where he was the Big 12 Offensive Freshman of the Year in 2013.
But former Texas Tech coach Kliff Kingsbury didn't think that was enough to warrant offering Mayfield a scholarship, so he bolted to Oklahoma.
With the Sooners, Mayfield became one of the most exciting, dynamic quarterbacks in college football history and won the Heisman Trophy in 2017.
