when did they move the field goal back
Field goal The goalposts were originally located on the goal line; this led to many injuries and sometimes interfered with play, and the NCAA moved the goal posts to the rear of the end zone 90 years ago in 1927. The NFL (still following NCAA rules at the time) followed suit, but moved the posts back to the goal line starting in the 1932 NFL Playoff Game, a change made necessary by the size of the indoor Chicago Stadium and kept when the NFL rules stopped mirroring the NCAA rules in 1933. The NFL kept the post at the goal line until 43 years ago, when they were moved back to the rear of the end zone for the 1974 season. This was partly a result of the narrowed hashmark distance of 1972, which had made for easier field-goal angles. The Canadian game still has posts on the goal line.
Field goal The longest field goal kick in NFL history is 65 yards, a record set by Matt Prater on December 8, 2013. The previous record was 63, originally set by Tom Dempsey and then matched by Jason Elam, Sebastian Janikowski, and David Akers. High school, college and most professional football leagues offer only a three-point field goal; however, some professional leagues have encouraged more rare kicks through four-point field goals. NFL Europe encouraged long field goals of 50 yards or more by making those worth four points instead of three (much like Australian rules' Super Goal or basketball's three-point line), a rule since adopted by the Stars Football League. Similarly, the sport of arena football sought (unsuccessfully) to repopularize the drop kick by making that worth four points; it failed, since only one kicker (Brian Mitchell) was able to do it with any semblance of proficiency. (In six-man football, where there is no offensive line, all field goals are worth four points instead of the usual three.)
