When can a kid drop Club lax if he’s not really interested in college lacrosse but wants to be competitive in Highschool?

Here’s the situation my son will go to highschool with a very competitive lax team. He really wants to play varsity lax in highschool. He is a good player on a top team. But honestly he’s not a world beater. In my estimate the only way he would play D1 or D2 would be to go to whatever team would take him. In other words, he would have to twist his college choice around lax. I don’t think that makes sense and While he loves lacrosse he’s not that committed. Is the smart move to wait till he makes varsity and then stop club?

Thanks in advance for your thoughts
