I guess that's why it's called an average...It was a pretty clear point. The reason you averaged nearly 20k is because you hosted 2 of the highest-drawing matches of the year. Your crowds are average without them. No other Sydney team got a huge rivalry to open the season nor did they get an ANZAC Day match.
Yes, their crowds without those matches averaged 15.5k. So average. In a year that they won the comp.
Take the top drawing games out of any clubs aggregate and the average will suffer, Souffs drew 60k against us...Dogs 50k on Good Friday...the Storm should draw well on ANZAC day, Eels got over 40k in Hindy's last game, Warriors have some big crowds at Eden park.
Take them out and those clubs' averages will suffer too.
I actually do get your point, I just don't think it's a good one.
