You can see whos in GA Southwest (2009 level) here...
Socal needs more ECNL options.
SDSC is Surfs way of keeping one foot in GA. WCFC needs to continue getting things together after the OC Surf days but I believe they used to be ECNL before going to DA. City has Duggan and he's guaranteed to go down with the GA ship. For the big socal teams this leaves Albion who just lost MW to Sharks. There's blood in the water and clubs are looking for a way out.
ECNL just needs to wave the golden ticket to 1 or 2 of the big GA Southwest clubs and it will collapse locally.
Another option would be for GA to take on some of the lesser teams in Socal so there's more local games. Problem with this approach is that GA would be admitting second tear status.
