My daughter will be graduating this spring and committed after her freshman year of HS. While I think the school and program remains the right one for her (lots of reasons why, only a couple are soccer-specific though the overall athletic dept figures importantly), I am a big supporter of the change in the rules. Sitting with her during meetings with coaches when she was just 14 was really odd - here's this very young kid and here are these very experienced soccer people and they are talking about money and playing time and college majors and everything else. She'd have really mature insights into some things (especially if it related to the pitch) but could not really speak with any insight about what she might expect in a college (the social life, the academic support, etc.)). Think about how many of us were ready to make such a big decision - the biggest to that point in their young lives and one of the biggest in any life - before even completing a year of HS? The new rule eliminates a feeling of pressure to commit - even if you have multiple offers or a lot of interest, especially as a GK, you feel pressure that THAT spot will be gone - before you have matured enough to have a real clue about college.
Your kids in the HS class of '21 fell under the first change in the rule, if my memory serves, and then about 6 weeks of the current rule so probably a number of your kids committed pretty early. I'm not going to sit here and say the kids should continue to explore options just because there's interest (I think that is risky for all but a very small # of kids) but I do think it is good to make repeated visits to the school of choice and to have real, deep, substantive conversations with your kid about the choice - those conversations will change as the child gets older, can talk with clubmates who are a year or two ahead, develops a better understanding of what a "college student athlete" means. You may uncover reasons why doing some quiet exploration actually does make sense or some opportunities to help reinforce why a good decision a year or two ago remains a good decision even as your child has changed (that was the case for us).
