This drill is when you place 6 basketball in the most common 6 positions on either side of the court that your players would shoot from.
Most likely at the posts positions the elbows the middle of the key and the foul line on either side of the court would work.
Then you set a low time limit for the players to shoot at all 12 spots (both sides of the court).
This will help the players shoot like they should in a game.
This also puts a time constraint on the player.
Then you can keep track of the most shots made by a player and have each player set a goal.
This drill enhances the accuracy as well as simulating game like conditions such as time.
I am actually a player and this is a drill my team has used.
