Postgame shows are generally shorter and less structured than pre-game shows, especially for national broadcasts. In many cases, especially in prime time matchups, there may be virtually no post-game show at all. This is partially due to the unpredictability of the length of a typical sporting event, which can vary in length by a considerable amount depending on clock stoppages and overtime. The post-game show is expected to fill the gap between the end of the game and the start of regularly scheduled programming. A team's success may also portend whether a post-game show is detailed or merely a summary of the box score and highlights.
