Receivers should give a hand target like they want the basketball.
Passers should be taking a step forward on the pass. They should not be standing straight up when passing, they should have their knees bent and really getting their legs into the throw.
The coach can change the type of pass being thrown as well as the direction of the jab step and cut.
One way to increase the intensity of this drill is to have one set of lines compete against the other. The players would count out their passes and the first pair of lines to 20 sits down and is the winner.
