The forward pass is legal anywhere behind the line of scrimmage. Previously, the passer had to be at least five yards back from the scrimmage line. This change is referred to as the "Bronko Nagurski Rule" after his controversial touchdown in the 1932 NFL Playoff Game.
Hashmarks or inbounds lines are added to the field 10 yards in from each sideline. All plays would start with the ball on or between the hashmarks.
To increase the number of field goals and decrease the number of tie games, the goal posts are moved from the end lines at the back of the end zones to the goal lines.
It is a touchback when a punt hits the opponent's goal posts before being touched by a player of either team.
It is a safety if a ball that is kicked behind the goal line hits the goal posts, and rolls back out of the end zone or is recovered by the kicking team.
