I have seen a couple games and i think those teams are less than ECRL squads. Pecking order for sure is MLS Next > ECNL/CSL Premier > ECRL . some of the ECRL teams can definitely compete with the ECNL/CSL Premier, and although a bit watered down, some top SCDSL Discovery Division teams are at the ECNL/CSL Premier level as well. EA may be more close to SCDSL Flight 1/CSL Gold
IMO (without considering the one-off/why is their 06 team so much better than every other team at their club... kind of team):
Like, as been said, LA Surf's 06 teams is really good. RCFC's CSL 06 teams could also beat some teams... and so on.
1. MLS Next MLS Teams. Ex: LAFC/LAG
2a. MLS Next Teams without an ECNL Ex: TFA
2b. ECNL Only Teams. Ex: SD Surf
Average D1 or top D2 High School
3a. CSL Premier: Ex: Anaheim FC, Glendale something or other team...
3b. MLS Next Teams with an ENCL/RL in same age group. LA Surf
Average D2 or down High School.
4. SoCal (SCDSL) F1: RCFC, Celtic, Newcastle, Sand and Surf, and so on...
Average D4 or down High School
5. SCDSL D2, ENCL Teams with an MLS Next Team in the same age group: By now you got the point of examples.... haha.
6. NPL/ECRL/DPL/Flight 2... Just go have fun and don't worry about rank at this point.
7. Intercities La Liga playing 11 v11 on a 40X70 pitch with a goat on the sideline and half the pitch is a baseball diamond... 100% happened to us. Great food options but not good soccer.
