Drop kick

In 1934, the ball was made more pointed at the ends. The creation of the pointed football is generally credited to Shorty Ray, at the time a college football official and later the NFL's head of officiating. This made passing the ball easier, as was its intent, but made the drop kick obsolete, as the more pointed ball did not bounce up from the ground reliably. The drop kick was supplanted by the place kick, which cannot be attempted out of a formation generally used as a running or passing set. The drop kick remains in the rules, but is seldom seen, and rarely effective when attempted. In Canadian football the drop kick can be taken from any point on the field, unlike placekicks which must be attempted behind the line of scrimmage.
