Understand the players respect each other more in R3PL - both my daughters have been subjected to lesser players fouling them intentionally at the high school level. It might make more sense to ask how much more "dangerous" is HS soccer than R3PL??
It would be easy to paint either argument with broad strokes - it's the isolated incidents that stay with my memory.
I'll always remember my oldest daughter being pushed to the ground from behind when she was a sophomore; clearly a cheap shot by a lesser player from a school not necessarily known for its soccer program. Referee calls a foul - no card, no "talking to", nothing. Because of that incident, she fully realized how dangerous playing high school ball can be.
No question, that incident - and others - at the high school level caused my kids to be stronger players - and put many gray hairs in their parents' heads!
