Like life in general, there are elements of football that made no sense until someone started doing them; other elements made perfect sense until someone stopped doing them. Such is the case with huddling. Football did not need huddling initially because it served no purpose until teams had structured plays. Once the rule of possession entered the game, offenses lined up in consistent formations and used preplanned plays called at the line. Football at the time had a nearly continuous flow. One play ended, the offense lined up on the ball for the next play, called the signals, and snapped the ball. The rapidity of running plays did not result from rules requiring teams to do so but because teams had done so when playing rugby.
