If the player you are guarding has the disc, it is your job to make it as difficult as possible for them to throw it. Your first responsibility is to start a stall count. Get as close to them as you can (you cannot be closer than the diameter of the disc) and say loudly, “stalling one... stalling two...” Your count should be in seconds. If you reach ten, it is a turnover. Spread your arms wide and challenge the thrower on each and every pass they attempt. Use your hands, use your legs. Move around and get in the way as much as you can, and don’t forget to keep counting. If they do manage to get a throw off, immediately shout “UP!” to let your teammates downfield know that the disc is on the way. Up calls, even on short passes, let your team know what is happening with the disc. This communication is critical in many situations as your defense will be too busy guarding the receivers to watch what the thrower is doing.
