An intercollegiate conference, which would become the forerunner of the NCAA, approved radical rule changes for the 1906 season. They legalized the forward pass, abolished the dangerous mass formations, created a neutral zone between offense and defense and doubled the first-down distance to 10 yards, to be gained in three downs. The rule changes didn’t eliminate football’s dangers, but fatalities declined—to 11 per year in both 1906 and 1907—while injuries fell sharply. A spike in fatalities in 1909 led to another round of reforms that further eased restrictions on the forward pass and formed the foundation of the modern sport.
