In my exploration of football around the world, I've found that different leagues play different types of football. While the NFL in America plays American football, known for its distinctive oval-shaped ball and unique scoring system, European leagues like the Premier League and La Liga play association football, commonly known as soccer. Australia's AFL plays Australian Rules Football, a fast-paced game with high-scoring action. Meanwhile, the Canadian Football League utilizes a blend of American and Rugby-style football. It's fascinating to see the variations of this beloved sport across the globe.
