My personal opinion is that the pressure up the middle is not as consistent as earlier, for whatever reason. At one time, we were consistently getting a great push up the middle...QBs were not able to step up; they were being moved off their spots and rushing throws rather than waiting for the perfect window. Many were lamenting the lack of sacks, but I maintained that I didn't care when the next sack ever came if we continued that pressure up the middle. With Ware, we might get two sacks per game from him, but the rest of the time he was running behind the QB, who routinely stepped up into a clean pocket because we never got inside pressure.
Lately, I'm once again seeing our DTs getting stymied more often, and QBs are having a clean pocket because Marinelli has proven that no matter what the offense is doing, he does not want to blitz often, preferring to play soft and prevent the long, quick TD. The difference between those first three drives that resulted in 21 points for the Giants and the next 5-6 possessions that resulted in only 7 points was the DL pressure which came to life at the end of the first half. Any good QB will pick apart any secondary if allowed to stand on his spot and wait on receivers.
While we all love the time Romo was afforded on that final TD to Dez, I've been surprised that no one has expressed concern that it took a full 7 seconds for any of our receivers to shake the least bit free...I find that also problematic.
Philly's OL has struggled and endured injuries...today, we must have pressure up the middle. If we can push the pocket in the face of Sanchez, it does well for the defense. If Sanchez has time in the pocket, he will have success.
