When coaching baseball, creating experience in each situation is key.  Explaining what to do is a necessary first, but actually experience is the only way to really learn.  For example one of the rules for tagging up is to tag only if you are intending to advance. When you tag, and when you take a lead to make sure the ball is caught, takes a lot of on the field experience.  The longer I coached, the more time we spent with situation scrimmages as described in the iBook, Practice Baseball to Win.
