A lot of sports concepts talk about "taking care of the middle" to approach a good unit. The Steeler 3-4 is no exception. Everyone knows you need pressure on the QB to succeed and that tends to come from edge rushers, generally speaking, and we need those too. BUT....think about when our D has been good in the modern era...what has it alway had and what has it not had when it is poor? A dominant NT first and foremost, followed by pro bowl ILB and a quality, if not great safety. The D in the the 90's was formidable. Our NT was Steed, and he was immovable. ILBs Kirkland and Brown were great. And SS was Lake, a perennial pro bowler in his own right. By 2000, the D regressed, as Steed was gone, and without that beast in the middle, that D won't fly. Kirkland was still here, but way too heavy to play like he once did. And our safeties were "Burn't" Alexander and Bell, not exactly pro bowlers. But the D started to be its old self (or at least show improvement) with the 1st round selection of Casey "Big Snack" Hampton. He was born to play NT. He wreaked havoc. No one could run the ball vs. us. And, oh by 2005 we had Farrior at ILB (heavilly valued by the team) and at S some guys named Troy and Hope, oh, and we won a ring. So, now, no more Hampton, no more Farrior or Shazier (from injury) and a pair of safeties that might be the dead last S unit in the NFL. And, are we surprised - without the middle of the D in good hands - that the unit is not getting it done? Why should we even be surprised? Hargrave was a decent value for where he was drafted, but he is no where near what a Steed and Hampton were. Having a NT who can get to the QB once in a while is nice, but the core job of NT is to gobble up space so the opponent can't run the ball. Until we get a NT of that caliber we will continue to struggle and our ILBs got to be upgraded in a significant way. And the safeties need an even bigger upgrade. If the team notices these trends, I could see us draft all D for 3-4 rounds, looking to upgrade all the middle spots: look for NT, ILB and S to all go early.
