Rugby and American football are two of the most popular sports in the world, but many people are not aware of the historical connection between the two sports. Although the two sports may seem similar on the surface, their evolutionary processes differ significantly.
Rugby originated from Rugby School in England, where the rules of the game were first formulated in 1845. As students from British public schools spread around the world, the culture of rugby gradually spread.
"Rugby's schism began in 1895 when 21 clubs from the north of England broke away from the English Rugby Football Association and formed a new league over player remuneration."
Following the split, rugby league and rugby union began to develop in different directions. Rugby League simplified its rules and changed team sizes from 15 to 13, making rugby league and rugby union two separate sports.
The Olympic format of rugby is called rugby sevens, with only seven players per team and each half lasting seven minutes. This kind of competition is quick and easy to understand for the audience.
As time went by, rugby was introduced to the United States in the late 19th century and gradually evolved into American football. At the time, American football was similar to rugby, and the United States even won Olympic gold medals in rugby in 1920 and 1924.
"The development of American football was driven by Walter Camp and John Meldrum Barnside, and many rule changes made the sport gradually diverge from traditional rugby."
The main difference between American football and rugby is the way the game is played. While American football employs the concept of "offense and defense rotations," where the offense needs to go through a series of "downs" to advance, rugby places more emphasis on a free-flowing style of play.
Nowadays, rugby has a considerable status all over the world, especially in the United Kingdom, South Africa and New Zealand. American football, on the other hand, is dominant in the United States and Canada.
"American football leagues such as the NFL and CFL are the two major professional leagues in North America, attracting large audiences and rising commercial valuations."
Rugby has a strong tradition in British culture and is often seen as a representative sport of the upper and middle classes. American football, by contrast, is more associated with working-class experiences.
Because rugby is an intense contact sport, the risk of injury is relatively high. During any given season, approximately one in four players will be injured. American football faces similar challenges, especially with the growing concern about concussions.
In the future, as the number of athletes and interest in rugby grows around the world, the two forms of sports are likely to continue to merge further. However, a growing number of professional leagues and international tournaments have also proven their own uniqueness.
As two different sports, rugby and American football have undoubtedly left a deep mark on the global sports world. Will there be more intersections and mutual influences in the future?
