The ball was made more pointed at the ends in 1934; this change is generally credited to Shorty Ray, a college football official at the time, and later the NFL's head of officiating. This made passing the ball easier, as was its intent, but
made the drop kick almost immediately 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.
While it remains in the rules, the drop kick is seldom seen, and as explained below, is rarely effective when attempted.
