You can say that about any defense if you don't have the right personnel. What hasn't changed, is if you can't get pressure from your front 4 (or 3) you're toast if your LBs don't have coverage skills.
Really? Isn't the "striker" merely a converted DB lining up as a LB. Didn't JJ do that 30 years ago in his 4-3?
What's gone are the 250 pound plodding LBs that Golden tried to turn everyone into.
