In my up coming The New Arms Race - Mega facilities thread, you will see that WCE, Hawthorn and Geelong are building facilities with MCG dimension ovals for training. I think Freo's new $109m facility shared with Curtain Uni, will have MCG dimension oval or they have access to one away from the new facility and Essendon's two ovals at Tullamarine are the exact dimensions of MCG and Docklands ovals.
My mate and I stood in front of the Williams family stand at the family day and he noticed the boundary in front of the Quinn stand seemed to be 2 or 3 metres further in from the fence than normal. He asked if I knew why and the only logical explanation I could think of is that we have changed the dimension of Alberton to be the same as Adelaide Oval. If the oval surface area, both length and width allows us to have the exact dimension as AO, including the right angle of the curves, then why not do it?
