Too many times in a game, the disc will be thrown, the player on offense will catch it, the defender will turn to their team and shout “Where was the up call?”.
However, it’s not up to your team to tell you where the disc is. Sure, an “Up” call will help, but you should also be aware and know where the disc is, where the offensive player is and be ready to make a bid on the disc.
Since the receiver already has the advantage, you must work on your field awareness in order to increase your chances of getting a D on the disc.
As I mentioned once before, my sporting love before ultimate was volleyball. Another tip I learned was when preparing to receive serve, you want to stand with your weight forward on the balls of your feet and slightly pigeon toed – that is with your toes slightly pointed in. The reasoning being that your ankle joint provides optimal force moving forward compared to laterally, and it’s even worse when your pushing backwards. So by angling your toes in, if you need to step left, the closer your right foot is to pointing to the left, the more force you can generate in that direction.
