u fight fire with fire, u need more fire than ur opponent to make it work
with 3-2, all u need is a better outside defense than ur oppoent's entry pass skill, and an on par reb skill from ur starting players
basically how the LI works is increasing the quantity & quality of the highest probability shot type and increase the probability of fouling out ur strongest starter.
a successful 3-2 limit the quantity of inside shot and hence contain the fire by taking out the air
o.reb is a problem but in LI, its the SF/SG getting the extra reb, and if ur C/PF ID can't contain SF/SG IS, it will be sosad
many people failed with 3-2 because they thought they can just flip the tactic and make it go, but they are only slowing down the entry pass, the ball still found another route inside and the LI fun began.
