Just to give you a point of comparison, my brother’s high school in Maryland (catholic, all boy) has a class size of about 250, but two years ago sent 16 graduating seniors to D1 lacrosse programs, and many of them to TOP programs - JHU, Duke, Maryland, Virginia, Navy… The 16 weren’t all starters (of course, since only 10 guys are starters and those aren’t all seniors), and the school did not win the state championship. That’s just how good and competitive east coast lacrosse is.
