This video is with Coach Joe Jones of Boston University.
The defender guards 3 different players in the 3 stages of the drill to rep several defensive skills in a short period of time.
You can certainly change the drill to fit your needs and or change it so that several baskets are going at once to get all players involved in a shorter amount of time.
