I’m not sure there’s a pair of teams in sports with more fitting colors to suit the brutality of the games they play against one another than the Pittsburgh Steelers and the Baltimore Ravens. It’s the color of bruises. As former Steelers CB Ike Taylor said, you spend days in the ice bath after those games.
For a variety of reasons, including changes in how games are officiated, Ravens-Steelers games aren’t quite so black and blue anymore. Certainly not in the heyday of the rivalry, in the era when players had rules informally named after them to reduce the physicality of the sport.
