i think you have boarded the wrong train, based on the advice of small-minded, competition-oriented coaches.
unfortunately for the youth athletes involved in these sports, from baseball to soccer, from basketball to football and track, parents and coaches with minimal, if any, background in exercise science, physiology, biomechanics, psychology, etc., just coach kids to play specific positions from a very young age in a given coach-driven tactical line up, and look for wins in the short run over athlete development in the long run.
i would ask: how many of your kids, who have learned the lessons of competing from age 6 or 8, as opposed to those comparable baseball players from the Dominican Republic or Cuba, etc., where individual athlete development is stressed over team-oriented competitions like US little league stresses, make the big leagues? i am guessing zero.
competition-oriented youth sports impede the potential of athletes in all sports, vs. developmental programs that stress individual development of skills, athleticism, strength, speed, endurance, agility, and behavioral maturity.
