Kansas City Chiefs fans have shaped Arrowhead Stadium into a breathing temple of tradition.
In the week prior to Arrowhead's 2010 wild-card clash, then-Baltimore Ravens offensive coordinator (and former Chiefs mastermind) Al Saunders told BaltimoreRavens.com, "The fans go there to be participants, not spectators. They take pride in being part of the game. It is loud. I mean, it...is...loud."
In the minutes prior to kickoff, opposing players pan around a red sea of hostility with a look that says, "I didn't sign up for this."
But in the past decade, the Chiefs' road to success has generally ended in detours, forcing fans to make a nostalgic U-turn down memory lane.
As a result, that same brand of hostility has gradually become color-blind.
