The Jets and Blues are playing the fourth best-of-7 series in Stanley Cup Playoffs history with the road team winning each of the first five games. The others: the 1951 Stanley Cup Semifinals (Canadiens-Red Wings), the 1995 Eastern Conference Final (New Jersey Devils-Philadelphia Flyers) and the 2004 Western Conference Final (Calgary Flames-San Jose Sharks). A best-of-7 series never has featured the road team winning each of the first six games.
Each game in the Jets-Blues series has seen the winning team trail at some point. Ten previous series in Stanley Cup Playoffs history have had comeback wins in each of the first five or more games, including four in the past decade: the 2009 Eastern Conference Semifinals (Pittsburgh Penguins-Washington Capitals, six games), 2012 Eastern Conference Quarterfinals (Flyers-Penguins, five games), 2012 Eastern Conference Semifinals (Devils-Flyers, five games) and 2014 Eastern Conference First Round (Penguins-Columbus Blue Jackets, five games).
