You must be talking about back dribbling 2!

If you are half a body away from him, the other party will generally not be able to knock you down. You may fall down if you are too far or too close. Since this kind of dribbling is difficult to knock down, I adopt the method of following closely. After the revision, there is a gap when pressing A, and you cannot use your back to swing twice, so as long as you follow it, it is still good. Be defensive, wait for him to knock him down when he makes another passing move, or wait for him to take a step and cover him! Remember, "half body", think about it yourself!
