Mt. Diablo Soccer has a very clear philosophy – its games are to be played so that they are a safe, positive, enjoyable, growth experience for the children. However, this is not achieved by adopting idiosyncratic or peculiar rules. Our games follow standard international soccer (FIFA) Law very closely, with only a very few changes to adapt to AYSO philosophy (e.g. controlled substitution to ensure that “everyone plays”) and, at the youngest age levels, to adapt the game to the physical and mental maturity of the players.
