Edward Franklin Camp, Jr. (December 23, 1905 – January 26, 1986) was an American football player and coach.
 He served as the head football coach at the University of Louisville from 1946 to 1968, compiling a record of 118–95–2 (.551).
 He is credited as the man who brought back Louisville football following a three-year absence caused by World War II, and has the most wins of any head coach in school history.
 NFL Hall of Fame quarterback Johnny Unitas was among the players Camp coached.
 In 1947, Louisville had a 7–0–1 season.
Gary Samuel Cuozzo (born April 26, 1941) is a former professional American football player.
 An undrafted quarterback from the University of Virginia, Cuozzo played in 10 NFL seasons from 1963 to 1972.
 He began his NFL career on the Baltimore Colts as a backup to Johnny Unitas.
 When Unitas was injured in 1965, Cuozzo replaced him until getting sidelined by injury as well, forcing coach Don Shula to use running back Tom Matte as an emergency quarterback.
John Constantine Unitas ( ; Lithuanian: "Jonas Konstantinas Jonaitis" ; May 7, 1933 – September 11, 2002), nicknamed "Johnny U" and "The Golden Arm", was an American football player in the National Football League (NFL).
 He spent the majority of his career playing for the Baltimore Colts.
 He was a record-setting quarterback, and the NFL's most valuable player in 1957, 1959, 1964, and 1967.
 For 52 years he held the record for most consecutive games with a touchdown pass (which he set between 1956 and 1960), until quarterback Drew Brees broke his long standing record on October 7, 2012.
 Unitas was the prototype of the modern era marquee quarterback with a strong passing game, media fanfare, and widespread popularity.
 He has been consistently listed as one of the greatest NFL players of all time.
The 2010 Towson Tigers football team represented Towson University in the 2010 NCAA Division I FCS football season.

The Johnny Unitas Golden Arm Award is given annually in the United States to the nation's outstanding senior or fourth-year quarterback in college football.
 Candidates are judged on accomplishments on the field as well as on their character, scholastic achievement, and leadership qualities.

 Unitas played his college career at the University of Louisville and set many records in the National Football League while playing for the Baltimore Colts.

 From Columbia University, he was drafted in the first round of the Common Draft as a quarterback by the American Football League's San Diego Chargers.
 Domres played in nine professional football seasons from 1969–1977 for four different teams.
 He is perhaps best known for replacing Johnny Unitas as the Baltimore Colts starting quarterback during the 1972 season.
Zak Adam Kustok (born February 24, 1979) is an American businessman who was starting quarterback for the Northwestern Wildcats from 1999 to 2001.
 He originally matriculated at Notre Dame, but suffered from a change in the offensive game plan when Bob Davie replaced Lou Holtz, who had recruited him.
 Early in his second season in 1998 he left the program and joined Northwestern after its fifth game in 1999.
 Despite playing only two and a half seasons for Northwestern, he is the current Northwestern record holder for many quarterback rushing and passing statistics, including single season and career rushing touchdowns, career rushing yardage, career and single-season consecutive games with a touchdown pass and career consecutive pass attempts without an interception.
 He was a 2001 Johnny Unitas Golden Arm Award finalist.
Earl Edwin Morrall (May 17, 1934 – April 25, 2014) was an American football player who was a quarterback in the National Football League (NFL) for twenty-one seasons.
 Morrall, who also occasionally punted, played 21 seasons in the National Football League as both a starter and reserve.
 In the latter capacity, he became known as one of the greatest backup quarterbacks in NFL history.
 During the 1968 Baltimore Colts season, he filled in for an injured Johnny Unitas leading to an NFL championship shutout victory and Super Bowl III, and for the 1972 Miami Dolphins season (both under coach Don Shula) he filled in for an injured Bob Griese leading to Super Bowl VII and the only perfect season in NFL history.
 Morrall made Pro Bowl appearances following the 1957 and 1968 seasons.
