Yeah, the auto double team needs to be patch. Right now I could safelly say that the man to man defense is broken since there is no way to stop your AI teammates from double teamming anyone in the low post. I would not be surprise if Scalabrine will be triple teamed in this game in the low post and he is rated 46 or something overall.
And I can confirm what you see in the video (thanks for the link videobastard) are all present and will constantly haunt your NBA2K10 experience.
I have however found some remedy. Since the auto double team will cause the AI opponent to be free, I set the shooting sliders to 40 (close, medium and long range) so they will miss 40% of the time. On ball defense to 100 to minimize the wide open shot of the AI opponent.
For the AI opponent spamming the paint, lowering the dunk slider to 45 makes them miss the cheap points.
But still, all this gameplay issues really needs to be adressed soon since the more you play the game the more annoying the issues are. Hopefully the PC version gameplay will not suffer the same fate. But with the mod community and all, it should not be a problem.
