This shooting drill is going to allow the player to get a lot of repetitions at the jab step go opposite shooting move, but it is also going work on a few other areas of the players game as well. It will teach the player to be able to make shots under pressure, as well as when they are tired. Since the drill is based on makes and not just a set time or number of shots, it forces the player to make shots to get out of the drill. It is also great for improving the players overall conditioning, and their ability to make shots when tired.
Basketball drills like this are also great for teams, because every player involved in the drill is working on a skill. It is primarily a shooting drill, but the passer must focus on making quality on time passes, and the rebounder must not allow any missed shot to hit the floor. Both of these are key skills that will translate over to a live game.
