Immediately following his retirement as a player, Egan was hired by Springfield Indians team owner Eddie Shore to coach the club, and the powerful Indians went on to win three straight first-place finishes and three straight Calder Cup championships under his aegis. His tenure under the turbulent Shore lasted three more seasons, but the Indians failed to make the playoffs in any of them, moving on to coach the Jacksonville Rockets of the Eastern Hockey League in 1966. With the team beset by injuries, Egan laced up the skates one final time, playing 19 games with the Rockets at age 47, after which he hung them up for good.
