I think it's a problem. I'm turning 19 in a couple of weeks and don't play Rugby anymore. I live in Queensland and I think there is the potential for so many more out of school leavers to be playing footy.
Most of the clubs don't have teams that go low enough to have lads the right weight involved.
A lot of the boys that play at schoolboy level in the 3rds and 4ths and to a lesser extent 2nds are drifting away and its rugby's loss. I think the clubs should work with schools close to them to get them to sign up and come down and play. Tell them it will be a good team, not a social team, a fun and enjoyable team that trains and plays hard, but isn't full of athletes, just journeymen.
For example in Brisbane - Easts should go to Churchie and more a less sign up their 3rd and 4th XV to come play. Wests should go to BBC.
IMO and this may be a little bias because I was a member of one but those 3rds, 4ths teams are the spirit of footy and they are the fans and backing of the game tomorrow.
Personally I like playing Rugby too much and will probably try and chuck 5kg's on and get back into it. I coach but I'm not that great a coach. I ref and love reffing a good game but nothing brings out the feeling of teamwork and pride like snatching a game against your rivals on the buzzer, as a supporter it feels great but as a player mmmm.
