Edward Scott Glacken (July 28, 1944[1] – December 27, 2006[2]) was an American football quarterback and coach. He played college football at Duke University. In 1963, Glacken threw for a school-record 12 touchdown passes. Glacken finished his Duke career with 3,170 yards and 24 touchdowns, helping the Blue Devils to a 15–13–2 record during his final three years as a player.
Glacken played two seasons with the Denver Broncos, leading them to a 1967 exhibition victory over the Detroit Lions, the first time an American Football League (AFL) club defeated a team from the rival National Football League (NFL).
Glacken would begin a two-decade long coaching career in 1970, taking the head coaching position at Georgetown University in Washington, D.C., helping to return the Hoyas to NCAA intercollegiate competition after a number of years as a club team.
Glacken retired as Georgetown's coach in 1992, having compiled a 98–94–2 record.
