In sports, the scout team, also referred to as a practice team, taxi squad, practice squad or practice roster, is a group of players on a team whose task is to emulate future opponents for the featured (or starting) players. Frequently used in American or Canadian football, these teams consist of less athletically developed or less skilled players. However, unlike a traditional scrimmage, scout teams often have to learn a variety of different football playbooks in order to simulate the tendencies of future opponents.
