Well the NRL are used to playing in largely empty stadiums, so it is a bit more interesting to see how the AFL goes without crowd input, both the players and the umpires.
AFL umpiring is more subjective and without crowds baying for free kicks there may not be as many, or home teams may not get an advantage.
