On the clock
When a play ends, the play clock is reset to 40 seconds.
From high above
Before offensive coordinator Josh McDaniels calls the next play, director of player personnel Nick Caserio gives him the Patriots’ situation from the press box, including down, distance, yard line, and time.
What’s the play?
McDaniels radios the play to Tom Brady, and also tells him what personnel is coming into the game.
On the field
In the huddle, Brady calls signals to let his teammates know who goes where and does what.
Only McDaniels has the ability to communicate with Brady. With 15 seconds left and the players lining up, McDaniels' headset box on his hip buzzes and then shuts off.
Brady calls play at line of scrimmage and identifies the middle linebacker.
Ready, set, hut
If Brady has changed the play, receivers line up in new locations, then Brady receives the snap.
