In college football's infancy, there were no hard and fast rules. It could be a very brutal game. In 1888, tackling below the waist was legalized and many players were getting injured, some fatally. Some colleges banned the sport. Four colleges convened in 1905 at the request of President Roosevelt to increase the game's safety. Head protection was one of the last places such equipment was accepted by players. In Marshall's early years, some players would wear a variety of headgear, while others chose not to. Here's a historical look at the development of Marshall's helmet.
