I don't think those sliders affect the number of times the cpu runs. I think if those are lower they may run more because they are having more success.
My question is regarding th coaching sliders and the % each coach's playcalling is split. That will make the cpu run more if the team is a running team all the time.
As an example, I played the Redskins & the Eagles. Portis is leading the league in Rushing but only ran 16 times in a close game. They never even tried to establish a running game. Adjusting the coaching Strategy may get them to run the ball more right.
