Association football

In association football, numbers were traditionally assigned based on a player's position on the field, with the starting 11 players wearing 1-11, and the substitutes wearing higher numbers. The goalkeeper would generally wear number 1, then defenders, midfield players and forwards in ascending order.

Numbers being assigned to each player in a squad was initiated for the 1954 World Cup

Very high numbers, the most common being 88, are often reserved and used as a placeholder, when a new player has been signed and played by the manager prior to having a formal squad number.

This NFL numbering system is based on a player's primary position. Any player wearing any number may play at any position at any time (though players wearing numbers 50–79 must let the referee know that they are playing out of position by reporting as an "ineligible number in an eligible position"). It is not uncommon for running backs to line up at wide receiver on certain plays, or to have a lineman or linebacker play at fullback or tight end in short yardage situations. In preseason games, when teams have expanded rosters, players may wear numbers that are outside of the above rules. When the final 53-player roster is established, they are reissued numbers within the above guidelines.

This numbering system originated in football's past when all teams were using some variation of the single wing formation on offense. When teams switched to the T-formation in the 1930s and 40s, the numbers were taken with them to whatever position evolved from the old single wing position. The system was first used in college football and was used only informally in the NFL until 1952; under the original, somewhat informal system, the backs were numbered 1–4, and the line 5–8.

Tailbacks or left halfbacks therefore had a number in the 10s. The blocking back, which evolved into the quarterback in the T formation
T formation
In American football, a T formation is a formation used by the offensive team in which three running backs line up in a row about five yards behind the quarterback, forming the shape of a "T"....

, had a number in the 20s. The fullback had a number in the 30s and the right halfback had a number in the 40s. On the offensive line, the center was in the 50s, the guards were in the 60s, the tackles were in the 70s and the ends were in the 80s.

In earlier times, defensive players would wear a number that reflected their offensive position, as many players played both offense and defense. For example, quarterbacks and halfbacks would usually play in the defensive backfield and so had numbers in the 10s, 20s and 40s. Fullbacks were often linebackers and had numbers in the 30s. Centers and guards were linebackers as well and had numbers in the 50s and 60s respectively. Guards and tackles played the defensive guard and tackle positions and had numbers in the 60s and 70s respectively. Ends had numbers in the 80s: split ends would be cornerbacks and tight ends would be defensive ends.

When the AAFC merged with the NFL in 1950, the AAFC players kept their old uniform numbers which caused confusion and resulted in the NFL moving to a standard numbering system in 1952. This resulted in many established players having to change their numbers in mid-career. Most notably, Cleveland Browns

, a less rigid numbering system is employed. The only rule is that members of the offensive line (centers, guards, and tackles) that play in ineligible positions (those that may not receive forward passes) must wear numbers between 50-79. Informally, certain conventions still hold, and players often wear numbers in the ranges similar to their NFL counterparts; though the lowest numbers are often the highest prestige, and thus are often worn by players at any position. Kickers and punters are frequently numbered in the 40's or 90's, which are the least in-demand numbers on a college roster. The increased flexibility in numbering of NCAA rosters is needed since NCAA rules allow 85-player rosters; thus teams would frequently exhaust the available numbers for a position under the NFL rules.

Individual schools often have superstitions or traditions involving certain numbers. It may be a great honor to be given the number "1" uniform, for example, at the University of Michigan

One of the more unusual football uniform numbering anamolies took place in what has become perhaps one of college football's most iconic games, the 1984 matchup between University of Miami and Boston College. In this game, BC quarterback Doug Flutie bested the highly-ranked Hurricanes and their quarterback, Bernie Kosar, on the final play of the game, when he found his roommate, Gerard Phelan, in the end zone to steal the win for the Eagles. While that play, and the game, may be etched in the memories of every American football fan, what is little remembered is the unusual fact that both quarterbacks wore numbers higher than the standard 1-19; Kosar wore the number 20, and Flutie wore the number 22.

A similar system is used in many European-style championships at national and international level; the Champion receives number 1, and others are allocated by either by a driver's placing in the previous season (3rd place the year before equates to race number 3) or by the team's placing in the Team/Constructor championship. If the Championship driver does not return, the Championship team will be allowed to use #1.

While it is also the rule in the Indy Racing League that #1 can be used by the Champion Team (Rule 4.4B) from the previous season, the majority of champions since 1998 have ignored the tradition because of team or sponsor requests to keep their normal numbers in order to keep their team identity, similar to NASCAR.

Retired numbers

Retiring a player's number is an honor bestowed on a successful player, usually after the player has left the team or retires from the game. His team will stop issuing the number that the player wore, and no other player from the team is permitted to use that number in the future (unless the honored player permits it). It is also bestowed on players who have either died or had their careers ended by serious injury. The first number retired by a team in a professional sport was number 6, retired by the Toronto Maple Leafs
