- The I formation is one of the most common offensive formations in American football. The I formation draws its name from the vertical alignment of quarterback, fullback, and running back, particularly when contrasted with the same players' alignments in the T formation. The formation begins with the usual 5 offensive linemen, the quarterback under center, and two backs in-line behind the quarterback. The base variant adds a tight end to one side of the line and two wide receivers, one at each end of the line.
