Mayfield finished his career as one of the most decorated quarterbacks in college football history, topping it off by winning the Heisman Trophy, Maxwell Award, Davey O'Brien Award, and the Big 12 Championship and a spot in the 2017 College Football Playoff. Mayfield completed 70.5 percent of his passes (285-of-404), throwing 43 touchdowns against just six interceptions (also rushing for 311 yards and five scores). The Big 12 Offensive Player of the Year led the nation in pass efficiency by a large margin (setting a NCAA record that he himself set the previous year) and yards per pass attempt (11.8), and finished in the top five of pretty much every other passing category. He was an all-state pick from Texas, but his lack of size scared major college programs away. He began his college days in Lubbock, walking on at Texas Tech. In his one and only season there, Mayfield started seven of eight games played, winning Big 12 Offensive Freshman of the Year (218-of-340, 64.1 percent complete, 2,315 yards, 12 touchdowns, nine interceptions). Tech head coach Kliff Kingsbury decided to open up the starting competition, so Mayfield left campus to find a new home. He sat out the 2014 season as a transfer student to Oklahoma (eventually, Big 12 coaches approved a rule that gave Mayfield an extra year of eligibility to make up for the lost season, as he was a walk-on that never received a scholarship offer from Tech). Finally on the field as the No. 1 starter in 2015, Mayfield became a second-team Associated Press All-American, Big 12 Offensive Player of the Year, finished fourth in Heisman Trophy voting, and was a finalist for the Davey O'Brien, Manning, and Walter Camp Player of the Year Awards. He also won the Burlsworth Trophy as the nation's top player who began his career as a walk-on after completing 68.1 percent of his passes (269-of-395) for 3,700 yards and 36 touchdowns against just seven interceptions. In addition to winning Burlsworth Trophy again in 2016, Mayfield was first-team All-Big 12, finished third in Heisman voting, and was a finalist for the Maxwell and Davey O'Brien Awards after leading the FBS in passing efficiency (196.4 rating, ranked first with 70.9 completion percentage, 3,965 yards, 40 touchdowns, eight interceptions). While his completion percentage was aided by horizontal throws, his mobility helped him find secondary targets and his ability to throw passes over the top of defenses also led him to lead the FBS with 11.1 yards per attempt. Mayfield was arrested for public intoxication, disorderly conduct, and fleeing/resisting arrest in February 2017. He was not suspended for those actions, though he was required to participate in alcohol education classes and community service.
