Stierle's own team had strong players from the LA Soccer Club team (including Sigi Schmid, who went on to play and coach at UCLA and coach the Los Angeles Galaxy), and won nearly all its games. To even things out and make the experience more competitive and enjoyable for the other teams, the policy of Balanced Teams was adopted, whereby the stronger players were distributed around the league. This had a slightly perverse effect, as some weaker players who formerly played every minute were forced to the bench by the newly-arrived stars. To overcome this, the policy "Everyone Plays" was adopted, which mandated at least half a game for all players. That in turn led to AYSO games being divided into "quarters" for the purpose of monitoring substitutions.

Girls:-

In 1971, two San Fernando Valley residents developed AYSO's first girls' program. Currently, 40 percent of AYSO's players are girls.

Special Olympics:-

In the mid 70s, an AYSO coach chartered new territory as he welcomed the organization's first player with Down Syndrome. As a result of this landmark union, soccer was introduced into the Special Olympics. Today, AYSO offers its membership the Very Important Player (VIP) program for kids with special needs. VIP boasts 75 programs and 1,500 players.

Sportsmanship:-

In the 1980s the policy Good Sportsmanship was adopted at the urging of Alan Witcher, a coach from the San Fernando Valley.
