If the gist of your argument is that IH lost 10 kids to private schools from lower grades who might have played football at IH, I'm not sure why that is somehow an indictment of the IH coach--IH is the wealthiest school district in SW Ohio (and maybe in the state), and the families in that district ARE going to be considering private schools-- several of which are located in close proximity to IH-- why is that even a surprise, or noteworthy?
Moreover, EVERY CHL school loses kids to private schools-- even Wyoming does, and their football team seems to be doing fine. If you think substantive numbers of boys in Madeira, Mariemont, Wyoming, Finneytown (and even Taylor or Deer Park or Reading) don't go to private school, you are misinformed. I don't see how this is an IH-specific problem-- nor why it should be laid at the feet of the football coach-- and somehow blamed on him.
