His playing career is best remembered for his role on the 1962–63 Loyola Ramblers men's basketball team, which won the 1963 NCAA Championship.

He was later scouted by Loyola-Chicago coach George Ireland at a Catholic League All-Star game and eventually offered a full scholarship, which he accepted.

[4] Loyola finished 22–5 but lost in the second round of the NCAA Tournament to Michigan, which Egan attributed to poor team chemistry.

[1] After graduating Loyola, Egan played three years in the short-lived North American Basketball League.

He worked in the Cook County State's Attorney's office in the late 1960s before starting his own criminal defense practice.
