Who picks up
Decide whether the first defender picks up at half court or as soon as the ball is inbounded. Place those two defenders first. The other three protect the middle and the sideline.
The trap
A trap is two defenders meeting on the sideline. Draw both closing down, then the passing lane you want to take away. Mark the defender who stays home so the drawing does not send all five to the ball.
If they break it
Add one arrow for the outlet pass you are willing to give up, and one for the rotation behind it. Save the press and the break as two plays if the picture gets crowded.
