This Stanley Cup Final rematch between the Boston Bruins and St. Louis Blues is 49 years in the making

    (CNN)A word to describe this year's Stanley Cup playoffs: chaos.

    For the first time, all four wild card teams advanced out of the first round and all division winners were knocked out. It also marked the first time that the top teams from each conference -- the Tampa Bay Lightning in the East and Calgary Flames in the West -- were eliminated in round one.
    Left standing for the Stanley Cup Final are the Boston Bruins and St. Louis Blues, with the best-of-seven series beginning Monday in Boston. They last met in the Stanley Cup Final in 1970, when Boston's Bobby Orr flew through the air after scoring in overtime in Game 4 for the sweep.
