Automating your skills allows you to release attentional capacity to attend to more critical elements of the game, and to grow as a player in terms of your decision making ability. Repetition can demonstrate that you have the personal ability to listen, change and repeat. All great players can listen, change quickly. They are able to take a detail and switch a key decision or skill component as simply as you would change a fuse in a fuse box. When you can listen and change you are going to get playing time, I guarantee you.
Coaches invest time in players who are quick learners.
Repetition results in more consistent performances in practices and games. The best players in the game yesterday, today and well into the future are those who can consistently perform. If you are not willing to put in repetitions, you will have to accept your performances will vary like the rolling hills of Kentucky. Consistency also results in higher levels of confidence which open your mind to learning more advanced skills and jumping to higher levels of competition. Repeatability demonstrates you can more rapidly think the game.
