The upper levels on the sides would have still been shit, they weren't going to knock down half the stadium and bring one side in 25m. The design was alright for the olympics but absolutely shitful for the remaining life of it which was predominantly going to be rectangle sports.
What should have happened IMO was in the original design for the olympics, was both side stands built 15m closer to the pitch but the lower bowl front row have a 5m drop off, then when the olympics was over, continue to build the side lower bowl down towards the pitch. It would have lost some capacity but did the joint really need a 110k capacity for the olympics?
I went to the opening double header in 1999 and the flaws of the joint were obvious for footy immediately.
The ends should have been demolished and brought in the 30m and the AFL told to f**k off but that argument is for another day.
