After graduating from Pitt, Davies began a long career as a college football coach. His first coaching position was as an assistant to the legendary John Heisman at the University of Pennsylvania in 1922. At the time of his hiring at Penn, "The New York Times" noted: "Tom Davies, former Pitt captain and all-American halfback, makes his debut as a Penn coach. The versatile Davies, who raised havoc with a number of Penn elevens in recent years, will instruct in forward passing, punting and straight arming, and will also help Tom McNamara with the scrubs."
