Side Line Officials
The Head Linesman and the Line Judge were not always positioned off of the side line.Sideline officials
The head linesman and the line judge are the officials who have the best view of the line of scrmmage before each play. Before each snap they line up directly across from each other from the opposing sidelines with the ball in the middle. Their pre-snap duties include knowing the amount of substitutes coming off of their respective sideline, a count of how many players for one of the teams, down and distance, and false starts as well as keeping the neutral zone clear of everything but the centers hand(s) and head.
The wing officials were not always on the side lines, at one point prior to the decade of the 1990s that these officials were encouraged to be just outside the widest offensive players, often smack dab in the middle of the field.
