This version of The Shell Defense Drill comes from the FastModel Sports Basketball Plays and Drills Library
The site has thousands of drills and plays that have been submitted by basketball coaches from around the world.
Traditional shell drills don’t always put enough pressure on your help-side defenders to make game-like decisions.
The Diamond Shell Drill changes the alignment to emphasize ball pressure, post defense, and backside help.
Offensive player exchanges force defenders to communicate, adjust their positioning, and maintain their help responsibilities.
The drill also incorporates baseline penetration to reinforce defensive rotations and the importance of stopping the drive.
