Carolina is the 12th NHL team to extend the defending Stanley Cup champions to seven games in the opening round and 10th in the expansion era (since 1967-68). Six have won, most recently the 2016 St. Louis Blues, who defeated the 2015 champion Chicago Blackhawks.
The Capitals are 5-11 in 16 Game 7s, including 3-8 at home. They will play a Game 7 for the 12th time in their past 20 playoff series since 2008, more than 17 current teams have played in their history.
The Hurricanes are 4-3 in Game 7s and 2-3 on the road but have won their past four. The only teams with longer winning streaks are the New York Rangers (six from 2012-15), Boston Bruins (six from 1983-94) and Detroit Red Wings (six from 1949-64).
The home team has won every game in the best-of-7 series, the 21st time that has happened in playoff history. The home team has won all seven games 10 times, most recently in 2016, when the San Jose Sharks defeated the Nashville Predators in the Western Conference Second Round.
Carolina's Rod Brind'Amour and Washington's Todd Reirden will become the seventh set of first-year coaches to meet in a Game 7. The last time it happened was the 1990 Adams Division Semifinals when the Bruins, coached by Mike Milbury, defeated the Hartford Whalers, coached by Rick Ley.
