What's the most important position in the 3-4 defense?

They say nose tackle but that was way back when every team basically ran the ball all day. Now in a spread league u can get away with a smaller nose tackle who is a penetrator plus the nose tackle is barely on the field with everyone passing the ball he isn't on the field when u run a nickel, bunkley is a freak and a great nose tackle go watch his game w the broncos vs thenjetsmin a 3-4 he absolutely owned nick mangold and was making insane plays

The whole point is getting pressure with a 3-4 so the most important position is if u run a 2 gap u need great linebackers if a 2 gap u need good linebackers and a good blitzes, my answer is outside linebacker
