Here is a drill that 2019 Missouri Valley Coach of the Year Darian DeVries uses to work on his ball screen defense.
Coach DeVries led the Drake Men’s team to the 2019 Regular season Championship in the MVC.
In the video, they are working on going under ball screens.
You can change angles and spots on the floor to get a lot of fundamental repetition on your ball screen coverages.
The video is hosted on You Tube.
