The 1951 team was undefeated as Roberts won the first of his two All-America honors and became a three-time All-MIAC selection. The National Football Foundation selected Calvin Roberts for entrance into the College Football Hall of Fame in 2003. Calvin was drafted by the New York Giants, but an illness prevented him from taking on competition at the professional level. Therefore Roberts then entered the Marine Corps where he was named to the All-Marine Corps team while playing for the El Toro Marines. Calvin later became a line coach at Augsburg College for a short period before entering a role as a teacher in physical education.
