What coach or parent has not used the talents of a famous player as an example? How they trained, their work ethic, stories of their youth and their skills on the field. These are all used by coaches and parents to motivate young players.
These examples not only show them skills to aspire to, they also serve to provide role models and as examples of their potential. Young players who watch and attend professional and national team games dream of being on that field and wearing the jersey of their favorite player or team.
