Preventative officiating, or not?

I think the coach was probably going there already, just based off the fact that he approached you and didn't quite know exactly what he should say. I don't know NFHS, but ASA allows this with no penalty (so long as the player may re-enter) if the offended team doesn't discover it first.

You straddled the line a little bit there, but sometimes for the sake of keeping the game moving along (and avoiding a long-winded explanation from the coach as to why he's so confused), you can push the line a tad.
