You bring a good point. Will Sydney have a bye in rivalry round? If not who would?
Remember. This is the AFL. The GC will have a bye and Sydney will play Brisbane in "The State-Of-Origin" epic.
Seriously though, as someone said earlier once the GC beat Brisbane the rivalry will kick off. Until then it will be less intense than the Showdown and Western Derby. It has the potential to be a very big rivalry.
