That's a glitch. It will look as though your sliders and the dummy sliders are the same at the main screen but load the game anyway. Then once it starts, user the dummy controller and go into the sliders and you will see it has retained the settings.
now, if only they really had a good effect. It seems extremely wishy washy. The CPU offensive running game is still weak, even after lowering my sliders as low as possible and raising the CPU run sliders to max. A big game from the CPU would be 50-60 yds rushing.
The RB AI isn't smart and runs right into tackles and doesn't take angles to avoid tackles. I have to make up house rules to no tackle them behind the line. I let tmy CPU copntrolled players run the D-line and they still bust it up!
