(1) A team's defensive half of the basketball court. (2) The collection of players consisting of a team's guards.
The physical backcourt is the back half of the basketball court behind the half-court line. The ball is often inbounded into the backcourt, especially after a change of possession following a scored basket or dead ball. Failure to bring the ball into the frontcourt by the team in possession within 8 seconds results in a backcourt violation.
The term backcourt is also used to refer to a team's starting guards (or those who have played the most minutes in any given game), including the point guard, shooting guard, and any combo guards. This use of the backcourt term is usually applied to overall scoring or performance by players in this category.
