If you're going to come at someone like that, at least get some facts straight. The 16/17 team came in 3rd during the playoffs. Pretty much the same team roster as the current 18/19 team that's struggling. http://www.ussoccerda.com/2018-Academy-Playoff-Standings-Girls-U15-U1617-U1819So what about their U15 team? That team hasn't lost a game. Did the girls from that team defect once high school soccer season began? My point is that it's harder to appreciate or feel the importance of something if you never experienced it. The girls that age into HS while on a DA team (u15) seem to be a little less drawn to HS soccer than those that have already developed a social network through HS soccer. I think it will take a few years to see how important HS soccer really is - assuming DA lasts that long.
I'll also quibble with your assertion that the quakes had dominant teams at the older age groups last year. Their 18/19 team finished in 8th out of 10 last year. And the 18/19 team only won two games this year before high school season began. The 16/17 team did finish second in their division last year, but couldn't manage to win a game in the playoffs. What teams are you referring to that were so dominant?
And the Earthquakes U15 team isn't even the best U15 team in their own county. Almost the entire squad on the best U15 team in their county played high school soccer.
