I'm also on pc and i think it works a bit differently to what people have described about the run plays slider.I don't see people standing around as much.Mostly it's with run plays higher the cpu takes more offensive options during a play(e.g. shooting when open on look to the post plays instead of the second entry pass etc.) rather than execute the whole play.The run n gun situation after misses is like described above...has to do with fastbreak slider and most importantly your own crash offensive boards.Not really sure yet.
One last theory.Have you experienced a lot less pick n roll plays with lowering down the attack the basket(to let's say 2 or 1)?Because players will attack regardless of how it is setup, if you give them lanes.I just had the impression i was not seeing enough pick n roll plays from the cpu.It would be rather confusing if these sliders work differently from pc to consoles.
