Problem is that those charging pass rushers/lineman leave gaps and you need LBs and safeties who can fill those gaps when you get a run, draw or shovel pass. I am not sure those players are on the Packers roster.
One thing that is odd about the Packer D is that if you two gap the D line you usually go smaller, speedier and deadlier elsewhere. But the Packers speed in the middle of the field is pretty average (except maybe Burnett) and their tackling is horrible. Sometimes it seems like a bad fit.
In other words, I still don't think this is all Cullen Jenkins fault
