You serious? You live in what you call a soccer Mecca and you don't know what the ECNL is?
For the past several years, the ECNL was the highest level a girl could play. College coaches skewed their recruiting to the teams that played in that league. Bias toward those players set in as coaches continued recruiting that leagues events. The thought was that they would put an ECNL club in all the big soccer markets and the best players would gravitate to that club, thus making it easier for college coaches to find and scout the best players from an area because they all play for one team.
Until just this year, the ECNL did not expand into Pittsburgh, so Joe's nieces team at Beadling and my daughters team at Beadling had to fight the "non ECNL" bias that college coachs had, even though they consistently beat ECNL teams every time the played them at select events.
Like Duquesne, my daughter also plays at a mid major. If she had played for an ECNL club, she would probably be playing in the Big10 or ACC. My daughter was part of a 9 player recruiting class at her school and she was the only non ECNL player in the class. My theory is that her mid major coaches go to the ECNL events, see which players have not committed to a Power5 school and then offer whoever is left. The problem is, the girls who are left are not standouts, but because they are on ECNL rosters, coaches over value their worth.
My daughter, probably due to ECNL bias, sat behind some of these players for a chunk of her freshman year. But these girls aren't that special. My daughter ended up overcoming that bias, rising up the roster, and is actually 3rd in the conference in goals scored in her sophmore year.
And now the ECNL has expanded way to much and there's way too many players and teams in the league. It's no longer "elite". Maryland United is the ECNL club in your area. In Virginia, there's Bethesda, McLean Youth, and newly BRYC (Braddock Road)
I never knew of or even tried to find out what the highest level was. My daughter played only rec league through the end of 7th grade, only played travel actually just one year, U15, just regional travel. two years in a local league they called select, because you had to try out, now 3 years playing high school, 1st year starting varsity in 11th grade. I always thought she'd eventually quit, playing soccer was never a priority, she's been doing ballet 11 years, soccer only 9 and most of the time it was rec with daddy coaches. But yeah, our area is pretty much a mecca of kids playing soccer, thousands of teams everywhere, just within one county, I know of at least 7 "travel teams" of varying strength you can try out for. And a big concern for us was, really this is just for fun, no expectation of any scholarship, so choosing which teams to try out for always the priority was somewhere close to home, like less than 15-20 minutes to practice and games. So no, I never heard of ECNL and I do live in an area totally oversaturated with kids soccer.
