For girls don't forget Albion Force and ECS. SDSC is an enigma great location great fields but terrible for olders.In my experience pre 11v11 in San Diego for girls it goes obviously Surf by a pretty significant gap… then City, Rebels, and Sharks all kinds right there behind
boys I’m not as sure for youngers , but I believe it’s primarily dominated by Surf, City , and Rebels. Also think SDSC has some strong boys teams
Boys is different because there's MLS Next which is a funnel of sorts (depending on who you play for) to pro soccer.
