The switch to a 3-4 defense

Before any retooling at all. Give it a draft and some cheap free agents and it might look better.

There's realistically no retooling possible to keep us from being an awful defense.

We don't have any cap space to sign any stud FAs.

We would need to draft slam dunk defensive studs to keep us from being awful which we haven't been able to do recently.
