The Roosters really have buried their 'small club, small crowd' stereotype haven't they?
With a slick organization, consistent success (anchored by 3 x premierships in the 2010s), and now a brand new stadium, I think they have revolutionized the rugby league product in Sydney. Their crowds have been great at Allianz 2.0 and are actually only growing year on year (particularly notable this year considering their injuries, slow start to the season, and home game vs South Sydney has been flipped from R3 to R27).
It's certainly left the likes of Wests Tigers and St George Illawarra Dragons (Sydney's long touted 'sleeping giants') in the dirt.
