Todd Haley didn't just hear about how Arrowhead Stadium used to be. Heck, he experienced it. It was loud and cranky, and if you were wearing some other team's colors, Sunday couldn't end soon enough. That was at the end of the 1990s, maybe the Chiefs' best decade. Kansas City was hungry for a championship, and when it didn't happen, that made Arrowhead an even more rowdy venue.
