No, the guard actually turns and looks back at the QB then taps the center. It's the darnedest thing I've ever seen and not be called for some sort of pre-snap illegal movement type thing. I think it might have started in the NFL many years ago? But, I've never stayed at a Holiday Inn Express so I don't know much and just guessing.So the left guard can hear but the center cannot? they are right next to each other.
