Sweeping rules changes were adopted by the NFL in 1974 to add action and tempo to games: one sudden-death overtime period was added for preseason and regular-season games; the goal posts were moved from the goal line to the end lines; kickoffs were moved from the 40- to the 35-yard line; after missed field goals from beyond the 20, the ball was to be returned to the line of scrimmage; restrictions were placed on members of the punting team to open up return possibilities; roll-blocking and cutting of wide receivers was eliminated; the extent of downfield contact a defender could have with an eligible receiver was restricted; the penalties for offensive holding, illegal use of the hands, and tripping were reduced from 15 to 10 yards; and wide receivers blocking back toward the ball within three yards of the line of scrimmage were prevented from blocking below the waist.
