发明名称 Basketball court
摘要 A basketball court is disclosed, having a circle on the floor under each goal hoop to clearly designate the area under the hoop. This is a critical matter in the playing and refereeing of the game, in the determination by players and referees whether or not the defensive player is directly under the hoop, and therefore may be subject to being call for a foul in the case of contact between offensive and defensive players.
