The Fundamentals of the Duck In and Seal

This offensive move can help post players secure position and create a target for teammates to pass to in the paint.

When you’re battling for position in the post on offense, there’s limited real estate to work with on the basketball court. You’ll need a variety of moves in your arsenal to receive the pass from a teammate and establish yourself in scoring position.

One of the most effective moves is the duck in and seal.

“The duck in and seal is an effective way to create space and a scoring opportunity near the rim, especially for post players,” says former high school and collegiate basketball player Jason Ronai.


As a post player, a good time to duck in and seal off your defender is when the ball is reversed from the other side of the court to your side. To execute the duck in and seal:

  • Stay low with your knees bent and chest up. Quickly move toward your defender and a position near the rim. As you do this, you should place an arm bar to your defender’s chest with your outside arm.
  • Drive your hip into the defender as you use your body to seal off the defender from the expected pass from your teammate. Through this process, keep your arms out and maintain a wide base. This can help you receive the pass in an athletic position. You should also be able to react quickly to a poor pass.
  • Once you receive the pass, use your positioning to finish with a layup or short shot.

“The duck in and seal move teaches players how to use their body to create space near the rim,” Ronai says. “Developing strong legs and core muscles will make the duck in and seal that much more effective.”
