A roster is a list of people who participate in an event of any nature whether it be competitive or not. Although rosters can be associated with non-competitive events, they are most commonly associated with athletics. Examples could be a team roster or depth chart in which the person's place on the team would be decided. The names of the places on a roster can be such terms as Starter or Backup, or for American football, First String, Second String, or Third String.
