to temporarily stop their football programs. In 1905 there were 19 fatalities nationwide. President Theodore Roosevelt reportedly threatened to shut down the game if drastic changes were not made. However, though he lectured on eliminating and reducing injuries, and held a meeting of football representatives from Harvard, Yale, and Princeton on October 9, 1905, he never threatened to completely ban football. He lacked the authority to abolish the game and was actually a fan who wanted to preserve it. The President's sons were playing football at the college and secondary levels at the time. Meanwhile, John H. Outland held an experimental game in Wichita, Kansas that reduced the number of scrimmage plays to earn a first down from four to three in an attempt to reduce injuries. The Los Angeles Times reported an increase in punts and considered the game much safer than regular play but that the new rule was not "conducive to the sport." Finally, on December 28, 1905, 62 schools met in New York City to discuss rule changes to make the game safer. As a result of this meeting, the Intercollegiate Athletic Association of the United States, later named the National Collegiate Athletic Association (NCAA), was formed. One rule change introduced in 1906, devised to open up the game and reduce injury, was the introduction of the legal forward pass. Though it was underutilized for years, this proved to be one of the most important rule changes in the establishment of the modern game. As a result of the 1905–1906 reforms, mass formation plays became illegal and forward passes legal. Bradbury Robinson, playing for visionary coach Eddie Cochems at St. Louis University, threw the first legal pass in a September 5, 1906, game against Carroll College at Waukesha. Other important changes, formally adopted in 1910, were the requirements that at least seven offensive players be on the line of scrimmage at the time of the snap, that there be no pushing or pulling, and that interlocking interference (arms linked or hands on belts and uniforms) was not allowed. These changes greatly reduced the potential for collision injuries. Several coaches emerged who took advantage of these sweeping changes. Amos Alonzo Stagg introduced such innovations as the huddle, the tackling dummy, and the pre-snap shift. Other coaches, such as Pop Warner and Knute Rockne, introduced new strategies that still remain part of the game. Besides these coaching innovations,
