In Maryland the holdback/reclassify is out of control. In the last two years all club youth lacroose went grade base to accomdate this disgusting aspect of holding kids back in sports.
The private schools are the engine as few public schools hold back kids unless its absolutely needed. MIAA schools are rift with these holdbacks. I personally know of one MIAA school grade that has over half the boys in it heldback!And it is common at many others. Many of the elite MIAA HS teams have many holdbacks/reclassify on them. Basically college freshman going against HS players. It will only get worst in MD, not better as more parents see the effect of holding your child back for an advantage. #1 MD club Crabs are the king of holdbacks and everyone wants to play for them , especially MIAA kids.
