What's the history here?
Boston and Chicago have competed for two pro sports championships. The Bears beat the Patriots in the 1986 Super Bowl and the Red Sox beat the Cubs in the 1918 World Series. But between the Bruins and the Blackhawks, the two franchises have never competed for a Stanley Cup.
However, because both teams come from the Original Six era, they have competed in six playoff series in the almost 90-year history of each franchise. The Bruins hold the edge, 5-1, sweeping the Blackhawks in their last meeting in 1978.
