One of the most difficult aspects of coaching is applying the right approach to each goaltender, at varying age levels. The reality is that not all goalies are created equal. As a result, goalie coaches have to adjust their methods based on a number of factors, including the age of the goalie, their experience, their commitment level and their talent level.
Good coaches know there’s no "one size fits all" approach to coaching. There are so many physical and mental challenges to the position that you need to assess each child (or young man, young woman or adult) individually.
