Coach counting

[RefCT]

I would stop it immediately. If their count doesn't match my count (which it probably won't), then they are also disadvantaging the other team - potentially making the other team rush because they think they are about to violate. Completely unsportsmanlike.

If the coach is doing it to trigger changes in his defense, he can figure out trigger words to communicate this without counting out loud. Hell, I wouldn't even care if he used the number on the count to trigger (i.e. at his 8 he yells 8 to trigger a trap) - just don't actively count out loud.
