For the 07 age group specifically, next year is a pretty important recruiting year for an MLS Next team that isn't part of an MLS Academy. After U15, LOTS of Galaxy and LAFC Academy kids are cut (like a third or more of the rosters at least) and most of those players have invested too much and love it too much to go to what they perceive as not the top league. A few want to play HS, but not that many as far as I can tell. They get a lot of playing time and the MLS Next clubs often give them opportunities to practice and/or play up with their U17 or U19 teams. There's a reason they were let go, but most of them have talent and the clubs that get the best ones can get better. Those that don't still pick up some pretty good players let go by the clubs replacing them with former MLS Academy players.
While some of this effect was just the fact that the MLS Academies couldn't really do the normal shuffle of players during Covid, most of it is because the U15 players have to get squeezed onto the U17 rosters and they don't want to carry a lot of players considering most of the U16 players are going to sit on the bench.
