Wow...so many parents that don't get high level sports. You think it's about ethics and morals. It's not. It's about winning. Always has been. Watch the recent news and see Russia and Kenya may be banned from Rio because of the overwhelming use of performance enhancing drugs. These are Olympic athletes that are some of best in the world but they still cheat for an advantage and to ensure they WIN. People so upset that some young men are a year or 2 older. Who cares. Always will be cheaters. Worry about your kid, your message to them and how they grow from competition. Win or lose. Maybe hold backs are same kids that using PEDs when older. You can't control other people's choices. Most on age kids could care less about hold backs. Next year there will be tons of kids older. Teach them to compete and not complain.
