“This is an example of a Backcourt violation. The offensive player, Buddy Hield, passes to his teammate, De’Aaron Fox, but the pass takes Fox into the backcourt to gather it. Since he is in his backcourt when he gathers the pass, this is a violation. Note that once a player establishes position in his frontcourt, he cannot move into his backcourt, nor may he pass the ball to a teammate positioned in the backcourt.”
