It's been said many times that Cincy is the AFC's closest thing to the Seahawks. Their offense even kind of looks like our offense in a way, they love to run the football with a physical RB in Hill, they have a semi-mobile QB who isn't afraid to run it, and they will use read option from time to time. Their defense is not ultra elite, but tough and consistent.
I think Seattle beats their asses in Glendale if it comes to that.
The AFC team I want to see is Pittsburgh. They haven't faced the NFC West since 2011, and they really don't have any frame of reference for a team like Seattle. Baltimore and Cincy aren't really in the same class as the NFC West in terms of nastiness and physicality. That, plus the Steelers defense has mostly sucked this season.
If the Steelers beat the Seahawks, it would give me a reason to hate them again. If they lose to Seattle, it's sweet revenge. I'm not afraid of a SBXL revenge game.
