Besides these coaching innovations, several rules changes during the first third of the 20th century had a profound impact on the game, mostly in opening up the passing game. In 1914, the first roughing-the-passer penalty was implemented. In 1918, the rules on eligible receivers were loosened to allow eligible players to catch the ball anywhere on the field—previously strict rules were in place allowing passes to only certain areas of the field. Scoring rules also changed during this time: field goals were lowered to three points in 1909 and touchdowns raised to six points in 1912.
