The 2003 defense was bullshit. In 2007 and 09 we held down some legitimate offenses (not the Pats though).
Whenever 2003 defense faced a legitimate team it folded like paper.
While I agree they were not as good as they looked statistically, they held the eventual Superbowl champ to 12 points and the previous year's Superbowl champions to 16 points. That's not bullshit, especially when the offense was led by Quincy Carter, Antonio Bryant, and Troy Hambrick. Had the current offense been on that team, they would have gone deep into the playoffs. Maybe won the whole thing.
Dallas's 2007 defense rarely held any legit offense down without major help from the Cowboys offense. That team relied on Romo and TO to score so much they made opponents 1-dimensional. The defense allowed 27 points three times, 35, and 48 points. Only twice the offense didn't score enough in those games to win.
The 2009 team played a lot of bad teams, and lost consistently to the Giants and basically any team with a balanced offense. The 2009 team's best effort was in New Orleans and even still they couldn't stop a 4th quarter surge that nearly lost the game.
You could count on the 2003 defense not to fold at the end. If they struggled, like at Philly, on Thanksgiving vs Miami, or at Carolina in the playoffs you could see them in trouble from the start. There's nothing wrong with being outmatched, but they worked their asses off anyways. That defense played with heart and Dat Nguyen expended whatever years of football he had left into that one season. Darren Woodson was also at his very best. If they had any semblance of an offense to help them; I mean
at all, they'd have done well.
People have contended that the 3-4 is easier to stock with talent than the 4-3, and I think the last several years have proved the exact reverse. You have to not only have talented players, you also need a beast of a coaching staff to put it all together and keep it going.
Regardless, offense has driven who will win the Superbowl this last decade, not defense.
