Well if the penalties are as posted above then there's a contradiction in how they work. Whereas more risk of a holding call makes the offense line more aggressive, greater risk of interference call makes the coverage more timid. So, the risk of a penalty being called affects different players differently.

Now, my experience of intentional grounding on both generations is that when it's high a QB will take sacks and scramble a lot more because they hold on to the ball fearing to throw away. When I turn it down, I get a lot less sacks because as I hit the QB he will often just chuck the ball on the floor in front of him.
