Garbage time

During the garbage time of an already settled American football game, the previously full stadium is now half-full and the substitutes are on the field.

In sports, garbage time is the period near the end of a timed sports competition that has become a blowout and the outcome has effectively been decided. Typically during garbage time, coaches of one or both teams replace their best players with substitutes. This gives playing experience to the substitutes, who are usually less experienced or younger players, and protects the best players from the possibility of injury.
