A native of Elkins, West Virginia, Moss played college football at the University of Maryland and was drafted in the fourteenth round of the 1952 NFL Draft by the Los Angeles Rams. He was traded to the Washington Redskins on July 11, 1952 for Nick Bolkovac and a sixth-round draft pick.
After playing one season in the National Football League with the Washington Redskins, Moss joined the United States Air Force and was stationed at Bolling Air Force Base in Washington, D.C. where he played for the base football team.

After one season as the Saskatchewan Roughriders defensive backs coach, Moss became head coach of the Ottawa Gee-Gees football team. He led Ottawa to the 1980 Vanier Cup and won the Quebec University Football League coach of the year award in 1982.
