The best way to draw a charge is to be sure you're positioned correctly. Stand in an athletic position and make sure your feet are planted to the floor. Next, you have to be mentally prepared to take contact. To get a charge call, you can not move from where you are standing. By being in an athletic stance, you allow yourself to be closer to the floor. Take the contact and the fall will be short. If you decide to stand straight up, then the fall will be much harder.
