The best-known type of draft is the entry draft, which is used to allocate players who have recently become eligible to play in a league. Depending on the sport, the players may come from college, high school or junior teams, or teams in other countries. An entry draft is intended to prevent expensive bidding wars for young talent and to ensure that no one team can sign contracts with all of the best young players and make the league uncompetitive. To encourage parity, teams that do poorly in the previous season usually get to choose first in the postseason draft, sometimes with a "lottery" factor to discourage teams from deliberately losing.
