Which team is the Broncos biggest rival?

Welcome to SB Nation FanPulse — a survey of fans across the NFL, powered by SurveyMonkey. Each week, we send 32 polls to 100+ plugged in fans from each team.

For the Denver Broncos, we asked who might be the franchises biggest rival. As a newly 40 year-old, my answer continued to be the Oakland Raiders. However, fans overwhelmingly voted for the Kansas City Chiefs in this poll.

That was when I realized that the Raiders really haven’t been relevant for almost two decades, while the Chiefs and Broncos have.
