Garbage Time

Garbage time, also known as "junk time", is a term used to refer to the period at the end of a timed sporting event that has become a blowout when the outcome of the game has already been decided, and the coaches of one or both teams will decide to replace their best players with substitutes. This serves to give those substitutes playing time experience in an actual game situation, as well as to protect the best players from the possibility of injury.

Garbage time owes its name to the fact that that period in a game is frequently marked by a significant drop in the quality of game play. This occurs for two primary reasons. First, the players involved during that time are generally less experienced, having not played nearly as often as the starting players. And second, the fact that seldom-used substitutes usually desire more future playing time means that when those players do play, they are often more concerned with making an individual impression than with executing team play at its best; this is especially true during garbage time because at that point, the matter of which team will win has already been decided anyway.

There are so-called "unwritten rules" for garbage time which indicate that the leading team should neither continue to play its starting players, devote unnecessary effort toward increasing the size of its lead, nor attempt particularly difficult and spectacular plays. Doing so is interpreted as an unsportsmanlike attempt to embarrass or humiliate the trailing team, and in some cases may also be seen as retaliation, either against the opponent or the critics of the team in general (see running up the score for a more detailed explanation of this type of behavior). However, sometimes a team may have a legitimate motivation for running up the score, such when margin of victory is a factor in rankings, as it was for many years in the Bowl Championship Series.

During garbage time, the trailing team can sometimes rack up an unusually high tally of statistics, leading the respective box score to be misleading with respect to their actual game performance. For instance, in American football, if the losing team is behind by several touchdowns, the offense may resort entirely to the passing game in a futile effort to catch up. At the same time, the leading team (on defense, with inferior players) may allow them to complete plays (which benefits them by running out the clock). This may lead the statistics to indicate a high amount of passing yards for the losing squad, which would suggest the team performed better than in reality. In general, although not always the case, it is not unusual for the losing team to have more passing attempts/yards than the winning team.

Particularly at the youth level, garbage time is eliminated by the use of a mercy rule, which automatically ends a game when the margin of winning has crossed a point that is commonly believed to be insurmountable.

The phrase garbage time is one of a number of commonly used basketball terms, each of which is thought to have either been coined by broadcaster Chick Hearn, or first given widespread exposure through Hearn's adoption of it for use during his broadcasts.
