The holdback / reclassifying is fueled by the egotistical parents of private school kids that can justify it solely on the grounds "because they can". Mathematically it makes no sense at all - but they can afford it! Tough for the U13AA player moving up to the U15AA team only to find out half of players from last year's U15 team are repeating. I would have a hard time watching my son abuse 8th graders when he should be playing high school lacrosse with his peers.
