Can we please stop pretending that anybody cares about three quarters of these so called "rivalries" in Sydney.
With the exception of a few games like Easts v Souths, St. George v Cronulla, and in the past Manly vs Norths and Manly vs Wests, most of the so called "rivalries" in Sydney are really just rivalries in name only.
Once you look under the surface there isn't really anymore passion or hatred in those games than any other, and the only reason that people call them rivalries is because both teams are from the same city, and lets be honest, that is the shallowest form of rivalry that there is to begin with, and when just over half of the competition comes from the one city and there're multiple "Sydney derbies" every week, it devalues the novelty of said derbies to the point where it's not a must see special event that only happens once or twice a season anyway.
I mean honestly, your average punter doesn't treat the vast majority of the Sydney derby games as must see rivalries, and never has, and just because Rabs and Gus will wax lyrical about the great "rivalry" between e.g. Cronulla and Penrith, that doesn't mean that they actually have a rivalry or that anybody particularly cares anymore about their matches than any other match.
