It starts with a whistle and ends with a gun.

Professional football in America is a special game, a unique game ... It is a rare game. The men who play it make it so. All of them are fearless. All of them are strong, quick. And all of them are part of a story that began long ago. A story written by men who found, in the sport, a demanding measure for their own courage and ability.

Pro football is a game not a war. It's for win or lose, not life or death... but say that in the summer, for winter brings the playoffs, and a season is at stake.
