Wow! This is a good thread. The concern is genuine and the consensus is that each individual is different. The pitfalls as well as the rewards have been laid out by several. I have been inolved in soccer for over 30 years and have coached, played, instructed and observed in the various states around the US. I have also observed the youth training in other countries. I would just add that travel soccer for the young ages should not interfere with school, friends and family. It should not dominate their lives at that age and the main focus should be on player development. Not just skills but emotional, mental and physical development. Kids can be scarred for life from a bad experience at that age. Anyway, the collective thoughts of all the above people is right on. Above all, soccer should be fun. Even ,my women's college team has to enjoy practice etc.
