1. St. Louis Blues
While not an Original Six rivalry, the Blackhawks and the St. Louis Blues hate each other as such. Since the NHL expansion in 1967, the Blues and Blackhawks have both been linked to major levels of success and having it come at the other’s expense. It also doesn’t hurt that the Cardinals and Cubs have a huge rivalry in baseball as well, essentially pitting the two cities against each other forever.
While the Blackhawks got the better of St. Louis early on in the rivalry, the Blues were able to start putting more and more pressure on the Blackhawks in the 1980s and really turned up the heat in the rivalry from there.
Since 1972, the Blackhawks and Blues have met 12 times in the Stanley Cup Playoffs, with the Blackhawks winning eight of those matchups and the Blues winning four. Three of those Stanley Cup Playoffs series wins for the Blues have come in the last four meetings between the two teams, with St. Louis coming out on top in the 1993 first round, 2002 first round and last season’s first round.
It took a few years for the rivalry to reach the height that it’s at now, but just like with the Blackhawks and the Kings and Ducks, mutual success and Stanley Cup Playoffs battles make for great heat and great hockey. The best thing going for the Blues-Blackhawks rivalry is that they still play in the same division, unlike the Red Wings.
The Blackhawks and Blues open the 2016-17 season on October 12 in Chicago, and the Winter Classic this year has the two facing off in St. Louis at Busch Stadium. This is one of, if not the hottest rivalry in the NHL today.
