The left tackle is the linemen on the left of the nose tackle in the defensive line.
IMPORTANT: There is also a left tackle position in the offensive line, but do not confuse the two.
Football Right Tackle
IMPORTANT: There is also a right tackle position in the offensive line, but do not confuse the two.
