There seems to be countless "how to back down" threads so I figured I could get through to more people with a thread, this is also not about the posting up you're used to so it's a different subject.
So your big guy has the rock. Make sure he's bouncing it (with his right hand, the defender to his left). Press the cursor that points towards the defender, then hit the power dribble/pro hop button with the cursor held. Your player will hit the defender with his shoulder. Takes a little practice to get it right.
If you succeed, it's an easy two or a defensive foul is called - if not, your guy lets go of the ball or you get an offensive foul. I feel this is more realistic and challenging compared to Live 2005, where most players would just give you the space when you posted up. Then again in 06 you won't even need this move if you've got your sliders on default.
What do you think?
