Why do NFL referees explain the rules of overtime before it begins?
When an NFL game goes into overtime, the captains of each team meet at midfield for the coin toss. Before the coin toss, a referee explains that overtime is a single 15-minute sudden-death period, each team gets two timeouts, there’s a 2-minute warning, etc.
Why do they do this?
The captains obviously know how overtime works. I assume it’s for the benefit of the watching audience but why do they assume that the audience doesn’t know how overtime works? They assume the audience knows about all the other rules of the game. Why is overtime any different?
