Two devastating weapons of a good defense are surprise and change.  Keeping your opponent guessing and out of any kind of rhythm is a very effective way to control tempo.
 
NUMBER ONE KEY….everyday we play 3 on 3 full court for about 15 minutes. It is controlled by the coaches. Usually stop and retake ball out at each end.
 
BOTTOM LINE: We want to put our 3 quickest guys up front after a field goal is made in a situation where we have worked 3-on-3 full court everyday. The three can guard the ball out of bounds or they can drop back and get in a 2-1- 2 full court set. They can ZONE out of this or TRAP or play straight MAN TO MAN. Your two back men are usually your 4 and 5 men.  
Note: We “might” show it after a free throw made depending on the situation. 

NUMBER TWO KEY…After crossing half court they fall back into a 1- 2 -2 half court “zone” (ALWAYS WITH PRESSURE ON THE BALL) or a match up that could be a box and one or a triangle and two or yet again man to man (you could throw in don’t go with first cutter but pick-up man to man after first pass. 
Note: Man on the ball forces baseline and other 4 show the man with the ball your numbers on your jersey (square up…packed inside)
 
As you see we are looking for confusion and change. They are not sure what we are in and we (coaches) aren’t always sure ourselves. They sort of feel it out of the daily 3 on 3 that those 3 do everyday. 3 on 3 everyday might just be our number one drill because if you look at it on both sides it is teaching pressure defense and attacking the press every single day.
 
I personally feel that there are going to be more and more “match up defenses” which again is trying to get the job done through confusion. We’ll just have to wait and see.
 
Note:  Watch California Poly San Luis Obispo and UCSB and tell me what defense they are running. Also remember Ralph Miller and his concepts at Oregon State university.   Very confusing with change.
