I get that, and agree the biggest current issue is not upgrading Strachan.Most clubs do though. If Gawn goes down for Melbourne (he never does though), they are playing Tom Campbell. I think the biggest mistake has not been upgrading Strachan.
Melbourne do have Tom Fullarton and Will Verrall developing on their list though. We don't have any pure rucks under 28 (T.Murray as more of a FWD who can chop-out).
Whether they are 19 or 22, I'm not as fazed - but we should be making room for one more IMO.
