How about the 9th grader who is better then the senior but has to wait his turn.
He's not, and that's what you knowingly signed up for ! That 9th grader doesn't even get to play JV. They play on all freshman team.
All while my son has been lighting it up on varsity since freshman year for a great public school program, and I mean great athletically as well as academically. He will go to a top 20 school with enough AP credits to enter with sophomore standing. And he has the excitement and experience of 4 years of varsity. Is there really even a debate?
