Lol 8k for ECNL. Not in AZ its closer to 12 with near multiple trips a month, out of state events and GA, ECRL cost pretty much the same with DPL slightly lower. Nail on the head as far as switching to letter leagues at around their freshman or sophomore year of HS. Those are the only years that matter.
With the new NIL roster spots and scholarships are reducing not sure any will get a full ride anymore, if they are that good then go straight to NWSL. Also how much would they have gotten without soccer? Most of these girls would get academic money regardless so soccer isn't likely financially benefitting them.
Don't know what the importance of D1 is other than the brag. Plenty of D2 and even D3 schools are better academically than the lower tier D1. 99.9% of these girls will stop playing after and sometimes during college so the dream will end you are just extending it. For those 99.9% the point of college is not to play sports but to get a degree that will get them a career where they can live comfortably. The difference between a degree from UCSD, UC Irvine, ASU, or NAU is much more marketable and will prepare them much better than some obscure Midwest or eastern D1 school. Plus staying in state reduces your travel and moving costs every year. Not to mention the stats of college students settling where they get their degree from. (hint its nearly 70%) If they can play at a school that has a great program in the degree field they are aspiring to great that works, you have hit the soccer jackpot. If not why are you handicapping their future career by getting a degree from a school you that would never have been on your radar if not for soccer. Sunk cost fallacy is crazy strong in youth soccer.
