A Fantasy Football League is a game where participants create their own virtual teams made up of real-life professional football players. Each player earns points based on their actual performance in games, such as touchdowns, yards gained, and other statistics. Participants compete against each other, and the team with the most points at the end of the week or season wins. Players typically join a league with friends, family, or coworkers, and they can draft their teams during a designated event. The league may have specific rules regarding scoring, trades, and player acquisitions, making each league unique. Popular platforms for managing leagues include ESPN, Yahoo, and NFL.com.
