If you're at all familiar with the history of football, you know that the sport has evolved greatly over the past 200 years. American football arose in the early 19th Century from a disorganized game played by violent mobs. It was a sport in which injury—and death—were not uncommon. Even after standardized rules were introduced in the 1870s, the game remained extremely dangerous due to brutal tactics like the flying wedge formation.
The brutality of football reached its peak in 1905, when a multitude of deaths and horrible injuries shocked the public into action. There were calls from many quarters to outlaw the game. Harvard—birthplace of the flying wedge—considered banning the sport, and Stanford, California, Duke, Columbia, and Northwestern actually shut down their teams. At this point, President Theodore Roosevelt stepped in and convened a meeting of college coaches to determine how to make the game safer. Out of this meeting arose a number of changes, giving birth to a governing body that would eventually become the NCAA. The rules were reformed, the flying wedge was banned, and the forward pass was introduced. It was literally a game changer.
