The St. Louis Blues’ biggest rival is the Chicago Blackhawks. The Blues entered the NHL through the 1967 expansion, while the Blackhawks were one of the first six NHL teams.
The Blues’ and Blackhawks’ hatred of each other goes way back, and their rivalry exploded 30 years ago. On St. Patrick’s Day 1991, St. Louis and Chicago fought tooth and nail for the President’s Trophy and faced off in a Norris Division game that would forever change the cold-blooded rivalry. The heated game was later dubbed as the “St. Patrick’s Day Massacre” as it should be.
