Position: Nose Tackle
Nose tackle (also nose guard or middle guard) is a defensive alignment position for a defensive lineman. In the 3–4 defensive scheme the sole defensive tackle is referred to as the nose tackle. The nose tackle aligns across the line of scrimmage from the offense's center before the play begins in the "0-technique" position]
In this position, frequently taking on the center and at least one if
not both of the guards, the nose tackle is considered to be the most
physically demanding position in football.
In five-linemen situations, such as a goal-line formation, the nose
guard is the innermost lineman, flanked on either side by a defensive
tackle or defensive end.
According to Pat Kirwan, a traditional 3–4 defense demands "a massive man who can clog up the middle," while a 4–3 defense is looking for "a nose tackle who relies on quickness to penetrate and move along the front."
The terms "nose guard" or "middle guard" were more commonly used with the five-man defensive line of the older 5-2 defense.
Effective against most plays of the day, but with a weakness to the
inside short pass, the 5–2 was phased out of the pro game in the late
1950s.] In the 4-3 defense, the upright middle linebacker replaced the middle guard. The nose guard is also used in a 50 read defense. I
