FWIW, Golden is correct in most everything he's said.
In defense of Cash, several people call defense's by the wrong name because they are disguised so well they give off the illusion of a 50, or the function of the 5th man is so close to what a 'down' lineman does, but that is really just responsibility based on what the offense does.
We run a 3-4 base and two gap most of the time. We like to stunt our DL quite a bit and that has led to some massive holes- especially on the cutback. The responsibilities we put on the SOLB are pretty remarkable and that is quite simply both why Shayon Green played so much (he knew his responsibilities), and why he failed so much (didn't have the athleticism required to perform well in the role).
I've read a lot on here about wanting to run the old school 4-3 to put pressure on the offense at all times, but a 3-4 honestly can put even more pressure than the 4-3. If you change the responsibilities of the defense and what you ask of them, you can get pressure off the edge much quicker than out of the 4-3. The reason is in the ability to disguise who's coming and from where. The downside is the complexity and difficulty finding athletes who can handle all responsibilities.
The way we run the 3-4 is simply built differently and requires a ton of talent to be effective.
