2k10's isomotion had good timing. You had to set moves up. Thats a good thing. That worked. It was also accurate. I normally got what I wanted. My issue was that it wasn't balanced. There still wasn't enough fumbles and picked up dribbles. Some isomotion moves, moved the defender automatically. That was the main issue I had.
I would not mind seeing it mapped to the right stick if we can keep the shot stick. Really I think changes have to start with the defense.
