question about ball moves in the game?

i still play nba live 06 until live 07 comes out.
And i don't understand what BOUNDARY FORCE FIELD IS USED for?

AND in the game for ex. exhibition match players pass ball
each other but these passes look bad to me . ball is flying i think.
not realistic and also i have question about shots
the same i think .

are we able to change these moves make them realistic and boundary force field option is about this?

or how do we change ?

please reply.

The Boundary Force Field slider controls how easy it is for players to step out of bounds. The higher the slider, the easier it is to stay in bounds when you're tightroping the sideline.
