Quota players
Quota players are athletes in team sports whose numbers in a specific team are limited due to the rules of specific competitions said team plays in. At present most of these restrictions are used to aid financial equality between teams or encourage the use of local players.
Such quotas can limit the number of players from outside a team's country, or limit the salary a players is on. Oppositely, quotas can also dictate teams have a minimum number of a specific type of player. Racial quotas have also been used in the past with the aim of combating racism.
