Yeah, I'm not a huge fan of the "Brovivors", because even though they don't join game together like a traditional pre-made, they're still a large group of good players who will always align.
I'd say the "Brovivors" this season are not that close, but AJ kind of forced them together by blowing up post-vote off, and made them a force to be reckoned with.
Right now the anti-brovivors have the numbers, since Ryan left last round, but the problem is no one except Nikki, Stephen and Adrianna have a clear idea of who is anti-Brovivor and who isn't. So that might end up being the Brovivors saving grace, that the anti-Brovivors doesn't fully trust each other, and doesn't know who are Broviors-supporters.
