1) Players A and B set the defensive line and do not reshuffle once set, with A communicating their role and defending inside runners off 9 while B communicates their role to 9 and defends 9 and potential forward runners. 2) C acts as the decision maker, communicating their role and calling for the defense to spread if the attack draws multiple defenders. 3) Numbers 1, 2, and 3 push out from C if late to the line and communicate their roles, defending their assigned channels or drifting depending on the attack.
