There is a lively discussion on the MLS page on Facebook as to whether SKC is automatically City's main rival and if so what to call it. https://www.facebook.com/photo?fbid=1082604485674822&set=gm.7744639878911351
I would've thought it'd be pretty even between SKC and CHI, so I'm surprised it's so strong in one direction.
Sporting KC, St. Louis City bring I-70 rivalry to MLS https://fox2now.com/sports/sporting...Tz6VhN1G9HyKDzyzDPTRgn7xYf5_Ys58j0POt2vtIHvlI
It will be interesting to see if KC ends up being our rival. St. Louis thinks KC is miles below STL. We’ve never had them as a rival in any sport.
I don't think there had been much rivalry between the Chiefs and Rams, but I thought I've heard people say that the Royals favs viewed the Cardinals as rivals even if the Cardinals fans didn't reciprocate. So there might have been some one-way rivalry even if not any two-way rivalries. That said, the one year we had "AC vs KC", it seemed like both fanbases bought into it. I'd still prefer it if we got more than one game per year with Chicago instead.
