Not going to happen unless the AFL can get out of the contract with the MCG and I reckon that contract would be watertight.
In any case the MCG is the biggest and best place to play the GF for supporters and the AFL and after all Yarra Park where its built on is the birth place of Australian Football.
Public disgust will see the AFL seeking to get out of the deal, wont like its national comp being regarded as a joke. It will cost $heaps, Premier Dan played a compliant AFL off the break.
