During the course of a game a player is sometimes going to have to make multiple reads in a quick period of time. They may have to execute a play, make a read on a ball screen, sprint back on defense, communicate, etc. So it is important that players are being trained to be able to handle this type of quick thinking, and being able to do multiple things at the same time while they are in the middle of the game.
This ball screen series drill is going to work on different specific skills, but it is also going to require the player to stay mentally engaged while they are doing the basketball drill. The player is going to have to execute multiple types of cuts and movements while they are getting fatigued from the drill. All this allows the player to work on their physical skill development, while also developing mentally as well.
