The 3-4 "vanilla" defence is no good unless you are gonna USE the flexibility it gives ya to create confusion and pressure on the QB. Playing a "conservative" 3-4 is playing to lose - not to win. If the DC want's to keep his job, he is going to have to show a bit of testosterone and turn those dogs loose so they can hunt! Keep tying them to the portch and they will be guarding your retirement home.
