I reckon that's pretty unfair.
They shortened the quarters to give them the chance to compress the season if necessary and they need to keep that card up their sleeve in case of any further interruptions.
I doubt anyone would want to see the times of quarters change part way through the season.
Tonight was a heavily contested game, played by two teams with limited preparations and plenty of rust, The short quarters didn't seem to worry too many people in round one when it was 16 goals to 12 v Carlton.
Heavily contested? You r on drugs.
