Coaching Baseball Hitters
When coaching baseball, instruction like those contained in the linked hitting lesson, from the iBook, Practice Baseball to Win, and drills are for practice. During games instruction relating to how to do fundamentals are more distraction than help. For example, shouting at a hitter to keep your head down, elbow up or down, swing level (probably the dumbest) etc. will keep the hitter from the task at hand. See the ball and hit it.
