Sports leagues are organized groups where teams or individuals compete against each other in various sports. These leagues can be professional, like the National Football League (NFL) or Major League Baseball (MLB), or amateur, such as local youth leagues. They provide a structured environment for competition, allowing teams to play a set number of games and compete for championships. In a sports league, teams earn points or wins based on their performance, which helps determine rankings. Fans often support their favorite teams, creating a sense of community and excitement around the games. Leagues also promote sportsmanship and teamwork, essential values in athletics.
