If the screeners defender is dropping, or maybe you are a good shooter so they can’t go under, or maybe its just sloppy coverage and your defender comes over the top of the screen, but lets you get in front of him. Check out Cory Joesph of the Toronto Raptors in this clip. Once he knows his defender is behind him he stops and waits to feel the defender.
This provides Joesph with a huge advantage. Once he feels the defender he knows the defender has stopped his feet. As the defender has stopped his feet Joesph accepts the contact and uses the contact to explode towards space for a finish.
