I read in another thread where the [lacrosse]'s Sporting Goods Tournament of Champions is requiring birth certificates to enforce age restrictions. Couple youth age restrictions with 4yr limitations for HS players and you will go a long way toward resolving reclassing issues.

It would neither prevent the kindergarten holdbacks, nor the 8th grade reclassers, but it would eliminate some advantages. Right now, an old 4th grader would still play with his classmates. Age restrictions would force him to play with the 5th grade teams. Additionally, many reclassed 8th graders play JV (or varsity) to continue their development. If these players were forced to play another year of youth, it would make this a less attractive option.
