He also was a member of the Denver Broncos and Houston Oilers in the American Football League (AFL).
Guy hails from Ellwood City, Pennsylvania, where he played for the Lincoln High School Wolverines.
According to his obituary, he was known as Buster in high school, a more fitting name for a star athlete than "Melwood from Ellwood".
Guy was selected by the Dallas Cowboys in the 1960 NFL Expansion Draft and became the first starter at right guard in franchise history.
In October 1961, he signed with the Denver Broncos of the American Football League as a free agent and played in 9 games as a backup offensive lineman.
