Well, this is the list of teams:
G2009 Discovery NPL
Beach FC 2009 Ko.Kutscher
Beach FC 2009 W. Lopez
CDA Slammers FC - HB G09 Elite
Las Vegas Surf SC Select G2009
Rangers FC G 2009 White
Sand and Surf SC G09 Elite
So Cal Blues G2009 Draluck
South Slammers FC G09 Elite
We have to consider that most of the flight one teams (from the last actual season,2019) have moved to either ECNL, ECRL or GA, so that left the door open for some teams to petition for Discovery.
2021 spring league and earlier tournaments results were also greatly affected by roster changes in my opinion.
