AYSO United. Lower cost uniform, not too many tournaments, lower fees. AYSO United did very well in the SoCal State Cup last year, particularly among the youngers.
Nothing in life is free though. There are tradeoffs to everything. The tradeoff here is that the organization treats soccer like little league: development is a lower priority...if they develop players those players when they get older may just go off to higher level teams...though they are backstopped by a crew of professional coaches to oversee things, the amateur coaches are of varying quality,...and many go into it not for the cash but for the glory of the win and to try to build a winning team (think fantasy football)....leads to usual short cut stragies: running game, long balls, kick it high over the GK, etc.
The other challenge for them COVID specific in Socal is that the entire pyramid recruitment has been destroyed by COVID. With no core season there's no way to ID All Stars/Select Teams. Extras teams were unable to do tryouts. United Teams that are already put together can continue training and recruiting here and there, but with big casting call tryouts stopped its very hard to build new teams.
