Moore moved to the San Francisco Bay Area in 1967. As a young boy he played for E. Berkovich & Sons, Hayward United, The San Francisco Scots and Tri Valley Soccer Club. He quickly established himself in the youth soccer culture, joining the Ballistic United Soccer Club as an assistant coach.
NASL
In 1974, the San Jose Earthquakes of the NorthAmerican Soccer League signed Moore as the team’s first player. Moore spent four seasons with the Earthquakes playing in both the midfield and as a forward. In addition to his playing field duties, Moore served as the Earthquakes assistant general manager from 1974 to 1976. In 1977, he was elevated to the position of general manager and team Vice President. However, at the end of the season, the Earthquakes made Moore a Free Agent as a player and he signed for the Oakland Stompers for the 1978 season. His life long dream was to play for his boyhood hero's Celtic FC from his home town of Glasgow in Scotland but unfortunately that never materialized. He was instrumental however in having one of his Celtic heroes, Jimmy 'Jinky' Johnstone, join the San Jose Earthquakes.
MISL
While it may appear from many accounts that Moore bounced through four teams in the Major Indoor Soccer League, this is deceiving. In 1979, he joined Detroit Lightning for its first, and only year in existence. At the end of the 1979-1980 season, David Schoenstadt bought the team and moved it to San Francisco, California, renaming the team the San Francisco Fog. After only one dismal season in California, Schoenstadt moved it again, this time to Kansas City, Missouri where he renamed the team the Kansas City Comets. Moore remained with the team through both moves and name changes, even coaching the Fog during the 1980-1981 season. While the team was last in the league standings, this season was Moore’s most productive one indoors, as he scored 32 goals in 40 games. He also suffered a concussion which led to his wearing a helmet. He began his final season in MISL with the Comets, but was traded to the Phoenix Inferno. Moore retired from playing professionally in 1982. During his three seasons in MISL, he was a two time second team All Star. After retiring from playing, Moore returned to the San Francisco area and served as an assistant coach to Roger Thomson for the San Jose Earthquakes during the team’s 1982-1983 MISL season. The NASL had run an indoor schedule in 1981-1982, but had decided not to have a 1982-1983 indoor schedule. As a result, the Earthquakes played in MISL that season.
National team
Having never played a first division match with a U.S. club, Moore earned his cap with the U.S. national team in an August 20, 1972 loss to Canada. He became a regular starter for the U.S. as it ran through its failed qualification bid for the 1974 FIFA World Cup. His last cap came on August 25, 1975, in a loss to Mexico, just as his professional club career was beginning.
On February 8, 2002, the San Jose Earthquakes of Major League Soccer hired Moore as the team’s general manager. He remained with the team for two years, gaining a reputation for building a solid fan base. The Earthquakes reached the Playoffs in both years and won the MLS Cup in 2003. On January 12, 2004, Moore resigned as the Earthquakes’ owners contemplated moving the franchise to Houston.
