Footwork has a big impact on the percentage of a shot going in or not. This is especially true when coming off of a down screen, or cutting out to the 3 point line for a shot. The shooter needs to do a great job of getting their body back towards the basket and squared up before shooting the ball. It takes repetition upon repetition to get this down the correct way, so it is important that you spend a lot of time working on developing great footwork coming into your shot.
This shooting drill will allow you to work on your footwork and shooting, even if you don't have a passer. That means that you are able to get the repetitions that you need, even without a partner. It is also a drill that can be used to work on conditioning as well. If the player executes the drill at a high speed, it will allow them to also develop their conditioning.
