“This is an example of a Backcourt violation. The offensive player, Kawhi Leonard, receives the pass from his teammate, Lou Williams, who had established legal frontcourt position. Since Leonard had not yet established frontcourt status when he receives 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.”
