Good reading!
On Daddy Dice's 3 level system of talent...what about level 4? you know, the crazy girl who is the 11/12th player on the team who thinks they know it all and whose parents compound the issue because they think she knows it all as well, the type of girl who always has some issue, spreads cancer like ebola in an african jungle, and wouldnt even be a starter on a school varsity team...
Commitment first is taught and instilled by the parents (now mind you, some people have it instilled in them, so in essence, commitment is alot like work ethic). In anything a kid does, in school, playing for a team, etc, they put forth a certain amount of instrinsic effort plus parents motivation. In the end, a girl learns from what she sees. She has a parent committed to getting her to practice when shes a whiny 11 yr old? eventually it pays off to the 16u girl who makes every school ball practice during the offseason, helping catch her varsity pitcher at camps and even makes the weekend travel ball indoor practice.
Some girls do fall by the wayside. they fall in love with other sports, maybe even band (hey i read on espn, a 6'4' all-american who went to uconn suddenly gave it all up to play volleyball). Parents dont have to push when it comes to committment, its just that inderstanding that comes with making a team and that families expectations. sure, every once in a while you will have a girl who has more drive then her parents, but its hard for teen girls to do this alone. what happens to that girl? they drop out and fall into that gray area level 3, and coaches shake their heads when their names are mentioned as "she coulda been a contender".
Cancers spread, and they take other girls and families down with them. If it becomes a coach vs. poor old me, drop em and move on. its not worth it, and if shes a top level talent, most likely she or her dad is emailing the coach letting them know their situation, usually the case of multiple sports.
