Was about to make this exact point.
It seems to me that the loss of atmosphere is largely due to the development of the ground. Lack of household names and a period of poor form contribute, of course, but even if we were coming dead last with a team of nuffies I still reckon the noise from a crowd of 11,000 six years ago would be higher than that coming out of 22,000 in the stadium today.
Unfortunately it's always been the case that you can hear a pin drop a few tackles after kickoff, it seems to be the nature of our crowds. But what we're lacking in recent times is the roll-on effect from the chanting initiated throughout the game. There was good noise on Sunday at critical times, and a lot of it coming from the Crusade's bay. Unfortunately though it doesn't seem to spur the rest on like it used to - perhaps people feel a bit more isolated from the mob, instead of getting excited sitting in a sea of chants.
While it might be a controversial question - and I mean this to be in no way critical of the fantastic job the Crusade do in the face of silent adversity - is Bay 2 the best place for a supporter's group? I remember the group massing in the south-east corner before the Andrew Johns Stand went up, and they were clearly visible and audible. The relative location hasn't really changed, but sometimes it seems like the grandstand has swallowed the group, tucked them away and dulled the voices somewhat.
I understand there's obvious reasons for the location, particularly the generous offer from the Knights to reserve the bay, however I sometimes can't help but think that location is a hindrance. Sometimes the Knights fans are out-chanted by opposition groups on the south hill - and sometimes they might not even be louder, it's just that their presence is more obvious. Would a supporter's group be more effective in the middle of the Eastern stand, or even going back to the hill?
Point of the rant being - while all the factors (Foxtel, form, prices, no more Rudder) contribute to smaller crowds, it's still a concern that those who do show up are stifled. And if people are unimpressed by the atmosphere on game day, they might just figure it's not worth tolerating what they used to and turn to Foxtel instead. Dunno.
