but being serious rugby IS a game for specialists, it's part of the fabric and beauty of it, part of what makes it attractive to people of different characters and different body shapes.
at the kids level the specialisation can be a wonderful thng, it brings some structure that the kids can work around, they know what their job is, it's a great alternative to football where a kid has no special role and can end up lost not knowing what to do, left out. In rugby you can give that kid a particular job to do, and suddenly he has a purpose and enjoys it.
I think the current fashions underestimate the value of specialist positions, and over-egg the dangers of kids being pigeonholed. My experience of followiing an age group from U7 to u18 is that very very many players have changed positons often several times, dictated by body shape, size realtive to the others (which changes) attitude, relative speed and fitness (which changes) choice and the needs of the team - often the needs must of the team
As just one example I can think of a player who went from second row (he was quite heavy) to hooker (everyone else got bigger than him), to scrum-half (a combination of the existing scrum half leaving and him having suddenly skinnied down and gone from plump to actually quite fast) to winger (the team have two other scrum halves now and he was a late developer - now he is tall, skinny and fast) I don't think that's particualrly unusual.
And I think that's typical. I really DON'T recognise this awful vision of 100s of kids trapped palying in a position they don't like.
What is other people's experience?
