Its been so long since we've gone after a great defensive guy (I guess McKenzie) that I find it very easy to agree with you. We DID get Fujita but he wasn't really a guy that almost every team coveted.
But everything SP said, the fact that its OBVIOUS we need a playmaker or two on D, and the way they went after Brees a couple of years ago makes me more optimistic. If they could have a defensive signing/drafting spree equal to what they did offensisvely that year, we'd be unstoppable.
