Below are some things I've been wondering about in-game play calling that I don't know the answer to...
Does Borges actually call EVERY play (aside from 4th-and-short-type decisions that Hoke makes)?
To what extent are the plays scripted?
Who is on the other end of Al's headset, and who is listening in? Assistant coaches? Backup quarterbacks? The NSA?
Who relays the play call to Denard? Do they just tell him a number that corresponds to a particular play on the play card he wears on his wrist?
Also, what's the backup plan in the event that Al's headset malfuntions suddenly during a game? Who would call the plays in that situation?
