OK, got it. I thought you were talking about the tuning update which you can delete. Yes, I turned game tuning to off and put fumbles at 40 and didn't see any. I don't use the hit stick, but the AI didn't force any either.
If you have the Defensive PI penalty slider set to high, you will have to lower INT.
I am going to test this a little more tonight. Probably going to lower Human Run Block and Fumbling to make the run game a little more challenging.
