I am not sure if the grounding at 100 compared to 0 makes a difference with the QB holding on to the ball. I didn't notice a difference has even at 0 I get like 8 sacks a game. I think either nothing makes a difference when it comes to the QB holding on to the ball to long or that having the QB slider below 50 I think may make a difference. When I first got the game I only had 5 sacks in 3 games and I was like what are people talking about the CPU doesn't hold on to the ball to long? Then after that I lowerd QB slider because like ever one to high of completion % and ever sences I lowerd it I have been seeing to many sacks like ever one else has been.
