A lot of no huddle teams get the playcall from the sideline by looking at HUGE black numbers and letters on huge white pages.
Additionally, when it comes to 2-minute offenses, a lot of teams will call more than one play from the huddle. So, maybe they call Pass Play A then Pass Play B then Pass Play C. If at any point an interception is thrown or a player gets run out of bounds, let's rehuddle and recall some plays, if not, this is the order we're playing in, and after C, we'll either call a time out, or spike it, or whatever.
It would be cool if it actually were more difficult to audible and hot route in loud stadiums...but it's not really. Just a minor inconvenience. I've never seen anyone do the wrong thing, get confused, etc. nothing.
As far as the OP goes, if you want to see your home stadium shake, plug in another control and control the away team.
