Baker Mayfield went from being a walk-on at Texas Tech to winning the Heisman Trophy at Oklahoma and becoming the first overall choice in the NFL draft. While his departure from Texas Tech was unexpected at the time, he now clarified that it was because of coach Kliff Kingsbury. Mayfield said during his Heisman acceptance speech that "someone has to be the face of the franchise" while pointing out that no Red Raiders were listed on the trophy's cover. He later signed with the Cleveland Browns as a rookie. Kingsbury left Texas Tech after one season to become the head coach at Arizona State. He was replaced by Matt Wallerstedt, who had been the team's offensive coordinator. Mayfield was drafted first overall by the Browns and will begin his career with them. He commented on his decision to turn down Texas Tech by saying "I think it's best for me to go where I can start right away." Mayfield's success at Oklahoma was expected since he came into college football with a lot of hype. However, what wasn't expected was his immediate impact on the field when he started playing right away. He led the Sooners to an undefeated regular season before losing to Alabama in the College Football Playoff. After his freshman year, Mayfield announced that he would forgo his remaining years of eligibility and enter the 2018 NFL draft. He was also named the winner of the 2017 Heisman Trophy.
