The Denver Post recently had a poll up on who the fans feel Denver's biggest rival is. The Chargers won by a land slide.
This baffled me as a lifelong Broncos fan-As I see it the Chiefs and Raiders have long been Denver's biggest rivals with the Chargers and the Seahawks being merely irritants through-out the years.
So to all you Chiefs fans. F*ck you and may we continue to hate you're team and loath in it's mediocrity for years to come.
