True statement right here. If you go and look at your player ratings you'll see that they have help defense ratings and double team effectiveness rating. So if your playing a team such as the Celtics if you change the pressure on rondo to loose and the cpu is guarding him, you'll see sagging off him anticipating helping. But you have to be careful which players you do this to cause if you do it to say a Ray Allen in he's in the corner and your playing loose off him. They can just throw a skip pass across court and it's money. Also certain players like Rondo make be hot at the time so you have to adjust accordingly.
