Lineman in American football. (See also American and Canadian football position names.) Linemen are the front players of the offense or defense of any play during the game. By rule, there are always at least five offensive linemen, not including the tight ends, that are on the line. The number of defensive linemen can vary from three to five players on the line.

Linemen are usually the physically largest and strongest players on the field. The physical size of linemen is necessary to protect the backfield players, or to push through the opposing line.

Without a strong offensive line, running lanes cannot be opened for an effective running attack. Likewise, without an offensive line effectively protecting the backfield, the quarterback will not have sufficient time for passing plays to develop downfield. Conversely, without a powerful defensive line to pressure the opposing quarterback, the opposing team can often pass at will without fear of the quarterback being sacked for a loss of yardage.

Offensive linemen are commonly compared to custodians, lunch ladies, and bus drivers. Their work sometimes goes unnoticed and their job is not as popular as the position of teacher, or principal. However, without these wonderful people, teachers and principals couldn't effectively do their job, just as the ever-popular quarterback could never do his job without his offensive line.

There are two types of lineman: offensive linemen and defensive linemen. The offensive linemen comprise the offensive line, while the defensive linemen comprise the defensive line. When an offensive lineman and a defensive lineman are compared to each other, the offensive lineman is usually the larger, stronger. The defensive lineman is the faster, more athletic.
