A fullback's primary job is to be a lead blocker. Similar to offensive linemen, fullbacks get very little recognition despite making important blocks the entire game. Unlike offensive linemen, the fullback usually lines up 2-3 yards behind the quarterback and may run with the football or catch balls thrown from the quarterback; however, it is rare for the fullback to touch the football (hence little or no recognition).
