The pick and roll is not used by me more than 2 times(or 0 times) , and people who play against didnt use it more,but i know how to stop more or less the pick and roll.
When the user call a pick you take to controll the pick man defender and then call for a doble team(circle in PS3) , Now you only have to take a good situation for the pass line to the free man.
With this, the ball man will be double and he cant do nothing only to pass , but the roll man dont cut to the basket.
This tactic isnt 100% effective, but has a 80% or more.
Try to do it and tell me your exit (or not).
Bye.
