Games behind
National Football League (NFL) standings sometimes report games behind, although the statistic is not emphasized; winning percentage is used, computed from each team's win–loss–tie record. This is especially true since the introduction of the bye week in 1990, exacerbating differences in the number of games that teams have played at various points in time, and since tied games (while highly uncommon since the introduction of overtime in the regular season starting in 1974) do still occur on occasion. Games behind is omitted from standings on the NFL's website and is absent from most published standings.
