It is easy to see football today and think the game’s evolutionary path was inevitable, but there is nothing pre-ordained about today’s game. Football might have taken any number of alternative paths, and often did, though many of those twists and turns are forgotten today. Consider that American football was played on a field with a 55-yard line and no end zones until 1912. Only the tweaking of the rules of the recently allowed forward pass led to the adding of end zones and the elimination of the 55-yard line. Likewise, the first wearing of numbered jerseys came in 1905 when rivals Drake and Iowa State met. Drake wore numbers between 1 and 25; the Cyclones wore 26 to 50. As numbered jerseys became popular, players were not numbered by position. Even when the NCAA mandated that player numbers correspond to their position, there were multiple systems proposed, including alphanumeric combinations tried by a handful of schools.
