I was reading about NFL europe http://en.wikipedia.org/wiki/NFL_Europe
that they introduced a 4 pt field goal for field goals over 50 yds.
Which makes it interesting when a team is down a touchdown it can come back and tie the score by kicking a 3 pt fg and and a 50+ yd field goal for 4 pts. It seemed an interesing rule change. I wonder if they would ever adopt that here.
