Rigby became a local and league hero and found himself on the cover of Sports Illustrated. He continued to provide positive exposure to the young NASL when he took fourth place in ABC's 1974 Superstars, a televised athletic competition pitting athletes from various sports.
February 1974 saw Rigby involved in another significant first. The NASL was toying with the idea of indoor soccer and the Atoms hosted the Red Army of Moscow team in Philadelphia's Spectrum. This was one of the first indoor games to use the configuration familiar to future indoor leagues, an artificial turf covered ice rink with small goals set into the far walls. While the Red Army team won, 6-3, its coach had high praise for Rigby who stopped 33 shots.
In 1973 Rigby earned his first cap for the USA in a 1-0 loss to Haiti. He played a total of six games, his last coming in a loss to Mexico on August 24, 1975. After a series of injuries and stints with other teams, Riby signed with MISL outfit Philadelphia Fever in 1979. When the NASL folded in 1984, Rigby became an indoor soccer star before recently settling down as a youth coach with Eastern Pennsylvania's Star Soccer Academy.
