Rugby: backrow moves right

Getting quite frustrated that my u10's are not using the space on the pitch and tend to bunch up. Despite various drills and game scenarios to force them to spread out and pass to someone in space they revert in any game to bunching up around the ball and taking it back into the thick of the opposition rather than looking left or right! Any ideas how to change their ways?

I have started an under 10s team up, and I would say about 8 from the 13 children I have , did not play rugby until about 6 months ago. Of these players, there seems to be a lot of potential, as we are scoring tries against teams, that very rarely concede tries.the problem I got with them, is that we are very poor at organising our selves in defense when the opposition has the ball, which does result in us conceding quite a few tries. We have some very good tacklers in the team. Can anyone offer some ideas on how I can get them to organise themselves? Thanks . Chris.

I have just started helping our head coach with under12's team. He wants to retire and has put me forward to be head coach next season. I am a little worried on how i should aproach training with the boys, going to a full 15 a side team on a full pitch. Any ideas would be greatly appreciated.

Positional rotation at U9 level... I originally posted this as answer to a question about squad rotation, but thought I might get a better response if I posted it as a question in its own right... I have an 8 year old at the age level you are talking about - he isn't the best player at the club by any means, but has his good moments. He loves watching the game, he has a good understanding of the way it is played (to the extent that he has often shouted at the telly over recent weeks at some of our illustrious stars when they're out of position) and he has good handling skills - to be honest he's just not brave enough in the tackle yet, but I know it'll come so I'm not making a big thing of it. However, he and a couple of others are constantly stuck on the wing, and are getting fed up with the fact that they don't get the opportunity to get involved much. The coaches seem to have their "big names" and as you say seem more interested in the short term aims of winning each game rather than trying to keep the lads interested and challenged each week. I know my son's aware that I think they should move them all around, although I have made a point of not criticising the coaches at all - I think he heard me talking about it to someone else. The coaches have talked about moving players to different positions, but haven't done it, and aren't really receptive when they are asked about it. There are two coaches, and the one that seems to have the "casting vote" is pretty autocratic and doesn't seem to accept criticism or suggestions. My son has mentioned about moving to another club, where he may or may not get more of a chance to shine, but I am not sure this is the right move as it may teach him to give up rather than sticking with something. Any thoughts please?
