LA Galaxy no longer exists and Royals are in. Many would argue the Royals aren't even the best club in AZ. But they are better than the other two AZ clubs currently in AZ
There is room for both, almost has to be. There is enough talent in CA that girls from GA and ECNL will move on to D1/D2/D3/NAIA etc, etc. schools. I won't argue that ECNL consists of the top CA clubs. There aren't enough roster slots available for all of the top talent in CA to play in these top clubs, thus the GA. They have the platform, the connections, and the clout to access coaches, YNT staff/scouts ETC. Will the GA stick around? who knows. They've done well during this weird year. Do they carry the clout in CA (at least in parent's eyes), not yet, maybe never. Will they place girls in college. Yep. Will they get YNT looks, yep.
Find a club in either league that your kid can play consistently on, find a coach with a track record of placement and you will be fine. The first day of college preseason, no one is talking about what league they were in.
Besides, I think it's silly that CA even has to be in ECNL. You guys are your own league. Just play each other, drive down the street, get in a good game, have coaches in attendence, and call it a day. Why drive to AZ or Vegas? I know it's not that simple but many would agree that minimizing travel is a good thing....keeping down costs expands the talent net.
