Personnel Packages, or ‘Offensive Personnel Groupings” found in the NFL, the NCAA, and other football offenses, and an explanation of the two-digit naming system.
In football, offensive personnel packages — also known as offensive personnel groupings — are commonly denoted using a two-digit numerical system that identifies the type of offensive personnel, and the number of each type of personnel.
Every common offensive personnel package has five offensive lineman and one quarterback, which leaves five players from the following three position groups: running back, tight end, and wide receiver.
The first digit identifies the number of running backs on the field, and the second digit identifies the number of tight ends on the field. Instead of using a third digit, the number of wide receivers on the field is implied; simply subtract the total number of running backs and tight ends from the five remaining players:
