掩护与突破的组合以四人成箱形落位为基础,先回忆练习过的三人在把握时机训练时的规则。首先,持球者保持三威胁姿势,做投篮或持球突破状,准备一对一进攻。第二,与持球者临近位置的队员,为摆脱自己的防守者,做V形或I形摆脱空切。以图1为例, A和C分别向篮球方向挤入,A为了接到球向罚球圈顶移动,C向前锋移动。 The combination of screenings and breakthroughs is based on a box-shaped set of four people, first reminding the three practicing rules in grasping the opportunity training. First of all, the ball holder to maintain three threat positions, do shoot or ball breakthrough shape, ready to one-on-one attack. Second, the player in the immediate vicinity of the ball handler, in order to get rid of his defender, do V-shaped or I-shaped to get rid of empty cut. Taking Fig. 1 as an example, A and C are respectively squeezed towards the basketball direction, and C moves toward the front in order to receive the ball toward the top of the penalty circle.
