I don't see anything about a West, Southwest, or CA conference, but there is this on the ECNL site:
https://www.eliteclubsnationalleague.com/ecnl-regional-league/
For "Regional League" teams in So Cal, I see the following:
- Arsenal
- Del Mar Sharks
- Eagles
- LA Breakers
- LAFC Slammers
- Rebels
- Slammers
- Blues
- Strikers
I haven't seen much info out there in the way of tryout announcements (I've seen quite a bit for DA, ECNL and DPL teams lately). Any insight on who is coaching, where the rosters have come from and any recent games played (tournaments or friendlies)? And any info on league play?
