These documents are a common method for individuals to participate in prediction pools centered around the National Football League. Participants select the winners of each game scheduled for a specific week of the regular season, in this instance, week 4. An example would be a document listing all NFL games scheduled for week 4, with space for entrants to indicate their chosen winner for each contest.
Such contests offer a recreational way to engage with the sport, fostering friendly competition and enhancing viewership. Their popularity stems from ease of participation and low barrier to entry, appealing to a broad audience regardless of their level of football expertise. Historically, these pools have been organized informally among friends and colleagues, but the advent of the internet has facilitated wider participation through online platforms and spreadsheet templates.
