This will never be stopped because there are too many loopholes in it for payment of big money to greedy players..
Heard of one club paying the players wife through a sponsors business. and another of $$$$'s being put into an account at a service station.
I think you can trust that whilst people are prepared to pay it, the SANFL can never stop it.
BTW, have a look at the club hoppers who move from one club to another on a regular basis, the coin dries up up so they move to the next best offer.
I could name many but you don't have to be Einstein either!
