|Head coaching record|
In May 1921, the Loyola University New Orleans hired Flynn as its athletic director and football coach. He was tasked with starting up an athletics program at the school, and he coached the football team in its inaugural season in 1921. Although the Associated Press described the first season as "unsuccessful", Flynn improved the team incrementally over his next two years. In 1923, Loyola compiled a 5–1–1 record. After three seasons at the helm, Flynn stepped down as coach and was replaced by Moon Ducote.
In 1934, he became the head football coach at Morristown High School in Morristown, New Jersey, a post he held until his death. A resident of Morristown, Flynn died on October 9, 1958 at Morristown Memorial Hospital.
