I cant imagine the ARLC would let the Magpies come back, and i doubt they would just let the Tigers die.
Souths have shown teams dont need a Leagues club to turn a profit, they just need some business savy, which (i would guess) the new ARLC board members while bring.
The positive side of the Balmain side falling over is that we will be able to finally leave Liechhart. I cannot see the Tigers ever being truely popular with games spread over 3 stadiums.
While i have doubts about Campbeltown being able to support a team on its own, SW sydney is where the Tigers need to be.
Ive already said it a million times but Liverpool seems their best bet if they were to move to a 1 stadium policy. It has reasonable access from Campbeltown and Camden areas but is still outside of the SW-bottleneck so its a location that will draw people from closer to the City ( from what i can gather, a large portion of the Cabramatta/Fairfield population are Tigers fans)
But a move like this will only be possible if the vested interests of the Leagues Clubs are removes.
