With a zone defensive strategy, the defenders cover an area rather than a specific person. The area they cover varies depending on the particular zone they are playing, and the position of the disc. Zone defense is frequently used in poor weather conditions, as it can pressure the offense into completing more passes, or the thrower into making bigger or harder throws. Zone defence is also effective at neutralising the deep throw threat from the offense. A zone defense usually has two components – (1) a number of players who stay close to the disc and attempt to contain the offenses' ability to pass and move forward (a "cup" or "wall"), and (2) a number of players spaced out further from the disc, ready to bid on overhead or longer throws.
