my dd played da/ecnl. plays power 4 now. and that was a lot of practice, a lot of travel and a lot of money. it definitely helps prepare you for a glimpse of what that life is truly like at the next level. it's a grind. everyday. if she didn't have the aspirations to play college soccer during her youth, past the 10th grade, i wouldn't have kept her at ecnl. there are other avenues to keep playing.
my son plays mls next, he is 15 turning 16 yrs old. practice is 5 days a week. and the residency is tailored to soccer, not school. you more or less fit school in with soccer. online, and fridays off because they are travel days and walk through days. you have to love it or it will consume everything in you. once again, i wouldnt support playing at that level if he didnt have goals and aspirations to play at the next level, whatever that may be. once again, there are other avenues to keep playing.
