Several principles need to be used in order to obtain the best results against any zone defense and they are;
– attack the seams/gaps
– dribble and pass penetration
– move the zone/distort the zone
– screen the zone
– skip pass and reversals/cross splitline
– dribble one way, pass the other
– your allignment
If the zone defense is a 2 – 3 setup then your allignment must be 3 out 2.
This is often called “odd guard front”.
Your baseline players must be “deep” at least at the level of the backboard.
