The cut is determined by the defense. When the offensive player comes to the perimeter, he immediately goes backdoor if the defender is overplaying him. We teach him to swing his outside arm up as if he is giving a target to the passer and v-cut off his outside leg hard to the hoop. As he turns towards the hoop he immediately brings his inside hand up as a target for the bounce pass. Please note that this hand must be low enough to catch the bounce pass.
Communication is important.
Both players have to talk. The movement of his outside hand also serves as a non-verbal cue. The passer has to read this. We prefer a one-handed pass off the dribble. The problem we have found with this is that the passer cannot check his pass.
