Why did American football replace traditional rugby in the US?
American football has been the most popular sport in the United States since the early 20th century, replacing traditional rugby in the process. The two sports have many similarities, but there are a few key differences that have allowed American football to take the lead. The most important difference lies in the rules and regulations governing each sport. American football has been structured and adapted to encourage a more physical and aggressive style of play, which appeals to many American sports fans. Additionally, American football has been adapted to include a number of safety rules, which have made it a much safer sport for athletes. Finally, the rules of American football are much easier to understand and follow, making it more accessible to the general public. All of these factors have contributed to American football's overwhelming popularity in the United States.
