That doesn't reflect the reality of college football today, IMO. If you give even a mediocre QB time to throw, he will make you look bad, as we repeatedly proved this season. If your DL isn't trying to push into the backfield, then the OL can ignore them and focus on picking up the pressure from the LB, and the QB can just sit pretty and wait for a window to throw. And QBs that grow up playing 7-in-7 don't need big windows to throw anymore.

Our defensive philosophy is: 1) We will play assignment sound football and wait for you to make a mistake, and 2) We will apply pressure in select spots. That doesn't cut it in today's college football environment, not against the teams we play now. QBs won't just make mistakes, not enough to keep good offenses (even mediocre offenses - Utah State, Nevada, Memphis) from putting up 35+ at least. You have to make the QB nervous at least 75% of the time he wants to throw it. You don't have to get pressure every time to do that, but he has to think that you are more likely to get pressure than not. That doesn't work if the DL doesn't make the OL worry about them getting to the QB, even in a 3-4.
