Football was derived from early versions rugby played in Britain during the mid-19th century. Walter Camp is considered to be the creator of American football, implementing new rules to the game of rugby such as team size, the creation of the line of scrimmage, the scoring system, and many other aspects of the game that are still adhered to today. American football therefore was established at the Yale campus in Connecticut in 1879. Early versions of football can be traced back to England with the highly unorganized "mob football" played with inflated balls or other spherical objects.
Uniforms now are slightly similar to the uniforms worn by football players during its early days. Current players still wear cleats and have similar socks and pants. However, there is more padding on the shoulders and chest area that previously did not exist, as well as large adjustments made to the helmet worn. There is now more protection for the face and back of the neck, as well as solid material surrounding the head. Gloves are now worn to aid ball control as well.
One major significant event in the history of football was the establishment of professional football. On November 12th, 1892, William Heffelfinger, a Yale graduate, was paid $500 to play for the Allegheny Athletic Association. He became the first professional football player and sparked the beginning of the establishment of professional football teams. The first official professional football game was played on September 3, 1895 between the Latrobe Athletic Association and the Jeannette Athletic Club.
One major challenge that American football currently faces is the debate over the establishment of new rules and regulations. A great deal of research has been done on the consequences of multiple concussions suffered by football players and their mental health once they retire. Many people are pushing for new rules regarding tackling, and others are attempting to redesign helmets and gear in order to ensure fewer concussions for players. It is argued that over the years there have been so many rules and regulations nit picking players that there won't even be real football in the future. Players are heavily restricted in the plays they make due to the constantly changing rules and penalties. American football is challenged with creating a safe environment for the players, while maintaining the original concept of the sport.
