My last comment on this...for all you dads who play your kids down you are making them losers. You are giving them biology for now which will eventually equalize when all of the boys mature. My 12 year old will grow from your mistake. Your sons will fall below their peers. Their peers aren't 12 year older. They are older kids. Make the game about the sport...not YOUR son whimsy score one or two goals on a smaller boy.
