Following the introduction of rugby-style rules to American football, Camp became a fixture at the Massasoit House conventions where rules were debated and changed. Dissatisfied with what seemed to him to be a disorganized mob, he proposed his first rule change at the first meeting he attended in 1878: a reduction from fifteen players to eleven. The motion was rejected at that time but passed in 1880. The effect was to open up the game and emphasize speed over strength. Camp's most famous change, the establishment of the line of scrimmage and the snap from center to quarterback, was also passed in 1880. Originally, the snap was executed with the foot of the center. Later changes made it possible to snap the ball with the hands, either through the air or by a direct hand-to-hand pass. Rugby league followed Camp's example, and in 1906 introduced the play-the-ball rule, which greatly resembled Camp's early scrimmage and center-snap rules. In 1966, rugby league introduced a four-tackle rule (changed in 1972 to a six-tackle rule) based on Camp's early down-and-distance rules.
