The players in the stack are lined up like Pez candies and the first one in the stack of Pez must cut towards the thrower before the next one can come out of the Pez stack and cut. Ultimate is a game of flow. A good offense is characterized by quick passes, one after the other, that quickly move up the field. One of the most tell-tale signs of a beginner team is the problem of 'clogging'. With fourteen players on the field at any given time, twelve of which are running in order to try and get open for the pass, things very quickly get chaotic, and disorganized.
People begin to find that it is difficult to get open because someone is always in their way.
Because picks are a violation in ultimate, you also find that occasionally you must stop so that you don't inadvertently pick an opponent. The Theory Players can now make running plays to try and get open for the pass. This is usually done in a cascade of 'cuts'. This sharp cut usually gets the player a step or two in front of the defense. It is important to get eye contact with the thrower just before the cut.
