Great story. While at Penn State, Urschel missed a practice. The coach looked in his chart showing which players had classes at what time. Color coded for underclass or post graduate classes. The coach saw a different color code, one that he had never seen before — so he asked his staff what class Urschel was taking. He was told “John’s not taking that class. He is teaching a post grad class in astrophysics.”
While still playing college ball, he had a paper published on two bodies in space orbiting a central point.
