2K11 questions

[vladiator]

Hi. I just bought the game. I played 2K10 and some things in 2k11 confused me in my first match. I would appreciate if someone could clarify them for me:

1. When dribbling with the ball in 2k10, I could hold LT (on Xbox) which would allow me to perform Iso moves, while still allowing me to actually run with the ball. In 2k11, it appears that I have to release LT to be able to run with the ball?

2. This year I need to hold both LT and RT to turn my back to a defender when near a post?

3. In 2k10, pressing LT when in "on-ball defense" initiated 'agressive' defense that allowed your player to follow the opposition's player a lot easier. Is this gone this year? (I play with JD's sliders, so maybe it is affected by this settings?)

Thanks in advance.
