One aspect specifically relating to Catholic schools that is often overlooked is multiple K-8 feeders feeding one HS. Looking specifically at smaller classes, but the fact that one HS might have 3-4 QB’s getting quality reps in MS, 6-8 RB’s, 15-20 OL, etc. While their public school counterparts have only one feeder school so competition starts in the 7th grade. Again looking specifically at boys how many public school kids lose interest because their classmates who matured sooner dominated all those positions in MS and walked away. Then the late bloomers are beasts when they’re upperclassmen but they’ve moved on to other things.
