NFL Overtime Rules Explained: Why the Format Keeps Changing
How the Format Works Today
NFL overtime is a single ten-minute period played in the regular season and a full fifteen-minute period in the playoffs. A coin flip decides which team receives the opening kickoff. Under the current rule, both teams are guaranteed at least one possession unless the team that receives the ball first scores a touchdown on its opening drive — in which case the game ends immediately. If the score is still tied after that first exchange, the game becomes sudden death: the next score of any kind wins. In the regular season, if the period expires without a winner, the game ends in a tie. In the playoffs, teams keep playing additional overtime periods until someone scores.
Why Both Possessions Became the Rule
For years the format allowed a touchdown on the opening drive to end the game, which meant the team that lost the coin flip might never touch the ball on offense. That arrangement drew steady criticism because it gave the coin flip outsized influence over who advanced. The league eventually guaranteed both teams a possession in the postseason after a high-profile playoff game in which the winner was decided by the opening drive alone. The change was a compromise — preserving the excitement of sudden death while removing the perception that a single coin flip could settle a postseason outcome.
The Controversy That Keeps Driving Change
Every meaningful reform of NFL overtime has followed a game that fans and team owners viewed as unjust. The format has shifted several times over the decades — from a full extra quarter, to sudden death, to the modified both-possessions rule — and each change has been retrospective, fixing the last visible problem rather than anticipating the next one. Regular-season ties and the-injury risk of extended play remain live issues. As long as a coin flip has any role in deciding who gets the ball, the format will keep inviting debate.
