Game 1 win matters

In the National Hockey League playoffs, winning the opener still tilts a best-of-seven series: teams that take Game 1 have won the matchup 68% of the time. (espn.com) ESPN used that number on Tuesday, April 21, to frame four first-round Game 2s: Montreal at Tampa Bay, Boston at Buffalo, Utah at Vegas, and Los Angeles at Colorado. All four series leaders had won Game 1 on Sunday, April 19. (espn.com) (nhl.com) The schedule made the stakes immediate. NHL.com listed Canadiens-Lightning at 7 p.m. Eastern, Bruins-Sabres at 7:30, Mammoth-Golden Knights at 9:30, and Kings-Avalanche at 10 on April 21. (nhl.com) The statistic is about format as much as momentum. In a seven-game series, the team that wins first needs three more wins, while the loser needs four of the next six. (hockey-reference.com) (espn.com) That edge is not a guarantee, and it is not evenly distributed. Historical data compiled outside the league show National Hockey League teams that win Game 1 on home ice have converted series at a higher rate than road teams that steal the opener. (sportsinsider.com) (whowins.com) That context fit the April 21 board. Buffalo, Colorado and Vegas opened at home and were trying to turn a one-game lead into a 2-0 cushion before the series shifted, while Montreal was trying to leave Tampa with both road games. (nhl.com 1) (nhl.com 2) The Canadiens-Lightning matchup carried an extra historical wrinkle. ESPN noted that in the four previous playoff meetings between those clubs, the Game 1 winner went on to win the series every time. (espn.com) (nhl.com) The broader point is simple by the time puck drop arrives for Game 2: the opener does not decide a Stanley Cup series, but the league’s own playoff history says it changes the math right away.
