Walter Camp would then be a huge impact in the football world. He proposed rules such as 11 players per team and established the line of scrimmage and also the snap from the center to the quarterback. He was also responsible for shortening the size of the playing field, as back then it was very large. Other things he had an impact on were scoring, making sure there were at least two paid officials during each game, and making sure players tackled below the waist.

Football would start to become popular around the country in the early twentieth century. Fans loved watching it for the fierce and intense competition. Players were starting to get paid to play around 1900, resulting in football becoming a professional sport.
