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.<\/p>\n

Every common offensive personnel package has five offensive linemen and one quarterback, which leaves the offense with five players from the following three position groups: running back, tight end and wide receiver.<\/p>\n

The first digit identifies the offense\u2019s 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.<\/p>\n
