My Nephew (8 years old) has recent started to play rugby with another bunch of clueless kids. Just wondering if anyone has experience in training younger kids in the fundamentals or rugby. Its full contact but there is no set piece at this stage. I'm not the coach, but I'd like to sound more informed then I actually do (I'm used to standing on the sideline shouting at the ref and telling the players to "kill em" and "hit em". Unfortunately that kind of carry on is frowned upon at an under-8's match). Anyhoo, the main issues are getting them to pass, and most importantly tackle other players on the move. Any suggestions on drills that can help them out?
