This topic recently came up and I thought I would ask it of the greatest Broncos fans in the world - so guys and gals of Broncos Country - which is the biggest rivalry the Broncos face?? We all know the Raiders are the historic rival, but their lack of success may have dampened that. The Chiefs and Broncos battled for AFC West supremacy in the 90's and early in this decade but they too are now struggling. The Broncos and Chargers are battling it out nowadays, and it appeared Philip Rivers and Jay Cutler were going to have their own personal rivalry going until the events of the off-season.
Please explain your answer in the comments. Call it a little "market research"!
So, I ask all of you -
