Kyler Murray is indestructible. Or he thinks he is. He runs with the freedom of inexperience. As Orson Welles said to Dick Cavett in explaining how he was able to make Citizen Kane at 26: “You’re sure it’s gotta be you’re good and you’re great. It’s ignorance. There’s no authority in the world like it.” Murray’s talent as a scrambler is completely uninhibited by fear of injury or failure.
Apart from the hamstring strain he suffered in last season’s matchup with Seattle, and an inguinal hip strain he suffered as a freshman in 2015, I could find no history of injury for Murray.
