Dough you make a very good point. Breaking into a quality team is almost impossible in some areas. Polished players who learn at a young age are miles ahead of late comers.
I am trying to understand Daque's point but it defies logic. We all know talent is the bases of any sport. That also involves learning skill sets and that involves reducing reaction times. I consider 15 to be the latest you should be involved with quality teams and instruction. Earlier even better.
