But I'm so old I played both ways and wore 13 as an interior lineman. And the goal posts were still on the goal line. (Nice extra blockers if you used them.)
A traditional NT is head up on the center. In a 43 defense it is not necessary. But a lot of teams use a 43 Over, made famous by the Tampa 2 defensive style, which shifts the strongside DT into a three technique and the weakside DT shades the center. Because of this formation, the weakside tackle must be a little bit stronger at the point of attack than a traditional DT. He is often called the NT to distinguish him from the quicker three tech.
