It's well known by now, but Mayfield played in eight games as a walk-on true freshman at Texas Tech in 2013. He left the program after one season -- citing "miscommunication" with coach Kliff Kingsbury -- and did not play in the Red Raiders' bowl game that year.
3. Arrest in Arkansas
Mayfield started 2017 on the wrong foot. He was arrested in Fayetteville, Ark. for public intoxication, disorderly conduct, fleeing and resisting arrest. He issued a long apology in the aftermath of the incident, calling it one the "biggest mistakes" of his life.
