When they are clapping their hands to indicate the center they want the snap does tha mean the entire cadence is silent or just the snap?
I don't know, I'll have to rewatch, but even then it might be hard to tell. Some teams go silent and the offense just goes on movement, some teams might have the center do the cadence after the QB signals he's ready, or it might be something else. And that might change from game to game.
