Being able to move without the basketball to get easy baskets adds great value to your game, and to your team on offense. To do this effectively though you need to work on being able to sell like you are going one way and then change it up.
These types of basketball drills are great for working on game specific situations that you will come across during the course of a game. This will help you work on selling that you are coming up to receive a handoff, and then cutting back door for the finish at the basket. In a game a big part of this move is reading the defender. If they are overplaying the handoff you will be open for the backdoor.
