Our problem at the moment is that the safeties have completely neglected their deep responsibilities, and we need another pass rusher. But last year it was pretty awesome when Danieal Manning was back there playing out of his mind and Peppers was beasting all over everyone.
That's the problem with Cover-2: it's great if you have 2 or more freaks of nature on the front four in their prime generating pass pressure on every snap with a four-man rush, but the minute one of those freak of nature DE/DT guys gets old, or gets injured, or leaves in free agency, your Cover-2 becomes a sieve-like defense. It's too dependant on rare, premium talent in the front four.
A more scheme-based defense such as Lebeau's fire zone blitz, or Rex Ryan's system, can weather the loss of a front-seven player more readily because it's easy to find replacement players to fit that scheme. Replacing a Julius Peppers, or a Warren Sapp, in a Cover-2 scheme, however, is a much more challenging task.
It's easier to find talented cover cornerbacks to fit a blitzing system than talented DEs and DTs who are freaks of nature who are big enough to play the run but also quick enough to rush the passer.
