It's funny how differently coaches look at this compared to umpires. I was reading this to a coach I know, and the coach stated the we should not say anything, and allow the defense to appeal. NFHS, the penalty for the first un-reported sub is just a warning. If we never give the warning, the coach, can in actuality, have three occurances of an un-reported sub before the coach and sub are restricted. So, what my coaching friend is saying is that we need to get the first warning on the books, so if the coach does it again, intentionally or not, then there are consequences for their either ignorant or deliberate violation of the rules.
I understand that position, however, I would still ask the coach if he wanted to re-enter #10.
