What's with the Pick & Roll???

Hey, in Live 07, whenever I call for a pick and roll, the CPU that is defending me presses up on me before the pick is even set. Then when I want to use the pick, i can't, cause im trapped between two CPU defenders and my player that is setting the screen. It's not that the entire pick and roll doesn't work.. its just that its COMPLETLEY unrealistic.

Is anyone else having this problem? Can I adjust sliders to stop this?

Hold down on the analog to protect the ball while the guy setting the pick comes over.
