Apparently, football used to be played a lot more like rugby is still played. 100 Years Ago today, Football's First Forward Pass was executed by St. Louis University when the coach was frustrated by his teams inability to move the ball. Of course, the first "projectile pass" was dropped by the reciever, but subsequent attempts must have worked better, since they won the game.
So what did they do before? Only hand-offs and laterals? Foward passing was actually against the rules until 1905 when it was prompted to be legalized by the deaths of several players(!) when things got a little too involved. Dang.
