Can anyone make a step back before shooting?

Do you understand what I'm saying? CPU makes a step back before shooting sometimes (like Iverson in real life) and it's very difficult to block this shoot. Please, help me.

for me
it is easy to block the shoot because when I see AI want to step back, I just keep close to that player and jump !

but i do not step back before I shoot !
I nearly got 20 blocks pre game !

I do the step back move... actually I do it way too much. I am so used to it that I try it with Ben Wallace and get the ball stolen everytime. It is a sweet move. I ussually drive a little, spin and then step back and shoot.

But, how can I make it? What are the keys?

I like the "Kobe Byrant Style" turn around jumper. It always works!

Keys? I dunno. I use the Analog stick.
