A spin move in basketball is a move used by an offensive player with the ball to get by the defense. It involves the ball handler getting to a defender and spinning his/her body 360 degrees while moving laterally to create space between him/herself and the defender.
To start, the offensive player begins by dribbling the ball in his/her right hand to approach the defender. Once the ball handler reaches the defender, he/she gets low and puts his/her left shoulder into the defender's chest. As the offensive player does this, he/she places his/her left foot, angled to the right, between the defender's feet. Both feet should be on the court at this point.
Simultaneously, the ball handler takes a strong, but controlled, dribble. This allows the offensive player to keep his/her hand on top of the ball through the entire move while still being in control of it. A stronger dribble will give the ball handler more time with the ball in his/her hand.
The offensive player stops his/her forward progress, but leans forward, placing more weight on the ball of his/her left foot, making sure to stay balanced. He/she then pivots on his/her left foot and picks up his/her right foot, turning in a clockwise fashion so he/she is facing the opposite basket.
Now, the ball handler's body weight shifts to the heel of his/her left foot as he/she continues to swing his/her right foot around. This foot should not stretch very far from the pivot foot. As the offensive player spins back so he/she is facing the defender again, he/she takes one more dribble with his right hand. This dribble, however, should be snatched back and end up in his/her left hand to make sure the ball is protected. Finally, the offensive player pushes off his/her right leg and blows by the defender.
One thing for players avoid when performing a spin move is transferring the ball to their other hand immediately after taking that strong, controlled dribble discussed before. This makes it more difficult to get away from the defender and gives the defender an opportunity to steal the ball.
A dribbler can use a spin move in a few different situations. The first is in the open court, when the defender is pressing, or at least playing far away from his/her team's basket. A quick, explosive spin move against a defender in this position can put the ball handler ahead of the defensive player and set up a good possession for the offense.
Moreover, a spin move is good for layups or other shots close to the basket. This can mean beating the offensive player's initial defender near the basket or against help defenders who are scrambling to help their teammate.
Finally, a spin move can be used as a reaction to good initial defense. When a defender beats the ball handler to the spot, the ball handler can smoothly transfer his/her forward momentum into a spin move that will set him/her up in the other direction, away from the primary defender. The spin move as a reaction or counter can be incorporated into any of the three above uses.
Setting up a spin move can help it to be more effective. Either stepping in the direction away from the intended spin move or crossing over, for example, can help to move the defender in the other direction. This will create more space between the ball handler and the defender.
On some plays the ball can be picked up after the dribble that starts the move off. Picking the ball up is effective if the ball handler is in heavy traffic and needs to protect the ball. As long as the player shoots the ball, or at least gets rid of it, by the time he/she takes two steps, this is not a traveling violation.
