At the end of all youth sports it boils down to talent regardless of age,size or class. As “Outliers” has now been debunked re:hockey age/size and age doesn’t guarantee size. The reclass issue seems to focus on seeking competitive advantage through size which is ludicrous because good coaches see through all of that anyhow and want skill + character. If your player can compete at 1 or 2 years ahead of their age they will have the requisite talent for always progressing to the top level of whatever sport they play regardless of size. Challenge them with that opportunity to rise to the occasion and for you as a parent to come to terms with their true ability, or lack thereof.
