Need to treat the Old Colls sides a bit different on that basis.
For simple reasons of the flow of juniors backwards and forwards PNU and TTG are going to develop a close relationship with Norwood, Glenunga with Sturt, Brighton with Glenelg, Goodwood with West etc.
Obviously it's never going to be perfect, but for example, if someone gives Garry McIntosh a call and he looks good at a couple of PNU trainings he tends to find his way out to Norwood pretty quickly.
Not like in the olden days, when we would have kids on the sturt list wanting to play with us but Sturt would make them go to Scotch OC
On this my impression is that the SANFL Clubs seem far far less minded to encourage players to return to anything other than their junior clubs.
Think they've worked out the importance of the symbiotic relationship/risk of biting the hand that feeds.
