Intercollegiate Football Association

The IFA teams, Columbia, Harvard, Princeton, and Yale, are now members of the Ivy League.

Harvard refused to attend the founding meeting, preferring to keep the Boston game, a cross between association and rugby football.

The rules were based largely on the Rugby Football Union's code from England, though one important difference was the replacement of a kicked goal with a touchdown as the primary means of scoring (a change that would later occur in rugby itself, favoring the try as the main scoring event).

Camp's most famous change, the establishment of the line of scrimmage and the snap from center to quarterback, was also passed in 1880.

At the 1882 rules meeting, Camp proposed that a team be required to advance the ball a minimum of five yards within three downs.
