There could be a back-lash by the public at the decision(s) though, as I heard one radio caller suggest. I think many if not most fans wanted a postponement rather than ‘business as usual’ with no crowds.
The traditional first game between Richmond and Carlton is always huge, 90-100 thousand crowd at the MCG, atmosphere is incredible. It’s going to look and sound so weird. And the commercial impact from that missing crowd(s) will affect the AFL and MCG financially anyway.
