Each point begins with the two teams starting in opposite end zones. The team who scored the previous point are now on defense. The teams indicate their readiness by raising a hand, and the team on defense will throw the disc to the other team. This throw is called a "pull". When the pull is released, all players are free to leave their end zones and occupy any area on the field. Both teams should not leave the end-zone before the pull is released. Thus, the defending team must run most of the field length at speed to defend immediately, and a good pull is designed to hang in the air as long as possible to give the defending team time to make the run.
