You guys have beaten this horse to death over and over again. These boys are almost in high school. If you talk about this at home your boys hear you and you are giving them built in excuses to not play hard against the holdbacks. What’s next? They get to high school and say “but dad, he’s a sophomore/junior I can’t beat him”. In the immortal words of Coach Boone “you’re crippling them, you’re crippling them for life”. The age cutoff is a unicorn, especially for this age group.
