American football
Shutouts in American football are uncommon. Keeping an opponent scoreless in American football requires a team's defense to be able to consistently shut down both pass and run offenses over the course of a game. The difficulty of completing a shutout is compounded by the many ways a team can score in the game. For example, teams can attempt field goals, which have a high rate of success. The range of NFL caliber kickers makes it possible for a team with a weak offense to get close enough to the goalposts (within "field goal range") to kick a field goal. Of 2,544 regular season NFL games from 2000 to 2009, 89 (3.5%) were shutouts.
