[1] In 1973, Philadelphia Atoms coach Al Miller, an alumnus of East Stroudsburg University, took Rigby as the first pick in the 1973 NASL college draft.

[2] Rigby became a local and league hero and found himself on the cover of the September 3, 1973 Sports Illustrated, the first soccer player to be so honored.

The NASL was toying with the idea of indoor soccer and the Atoms hosted the Red Army of Moscow team in Philadelphia's Spectrum.

While the Red Army team won, 6–3, its coach had high praise for Rigby who had stopped 33 of the Soviets' 39 shots.

The Cosmos then brought in Shep Messing to replace him in goal and shipped Rigby to the Los Angeles Aztecs at the end of the season.

The Fury attempted to build on the Atoms' popularity by bringing back several fan favorites, but the team only lasted two seasons due to incompetent management.

In 1985, the Earthquakes joined with three independent west coast teams to play the Western Alliance Challenge Series.
