in all my years of coaching I didn't know THEN how that actually works. It comes up so seldom!
Here's the way we worked it in my 'coaching' days... when a timeout was crucial we SCREAMED it at every player on the field and MORE than audible to the officials.. whom I made sure were 2 inches from the words coming out of my mouth to let them know it was coming.... but who called it? Oddly, I don't know... or I do... everyone on the field called it... but were they watching me? The Captains? The QB? I don't know. - JamesJM
