My point was that none of those Ds were stacked.
They were lead by league leading offenses that jumped on teams and forced them to abandon the playback and play from behind (pass a lot to play catch up, generally leading to inflated Sacks and INT numbers).
Having a good offense can easily tank the other teams gameplan. And if you're able to get timely stops on 3rd down and a couple important sacks, that's all you need.
Those 4 teams, and 2012 Giants, all won with timely stops, not necessarily "stacked" defense like the point you were trying to make.
Nothing wrong with paying Dez if we can get timely stops with Hardy, Lawrence, and Gregory.
