For all of Patrick Mahomes’ success with the Kansas City Chiefs, it can be easy to forget that the soon-to-be 30-year-old quarterback was once a backup struggling to learn the position behind starter Alex Smith. Drafted 10th overall out of Texas Tech in 2017, Mahomes arrived in Kansas City with experience in then-Texas Tech head coach Kliff Kingsbury’s spread offense, but still lacked some basic fundamentals. ‘He was yelling his first play into the huddle,’ Chiefs offensive coordinator Matt Nagy remembered, as quoted by ESPN.
