The Montreal Canadiens walked into Buffalo believing their playoff resilience would carry over from an emotional first round triumph against the Tampa Bay Lightning. Instead, a Game 1 defeat at KeyBank Center delivered a brutal wake up call.
Martin St. Louis did not sound panicked after the Canadiens’ 4-2 defeat at KeyBank Center, but the Montreal coach made it clear his team had just encountered a completely different monster. Buffalo’s transition speed, relentless forecheck, and suddenly lethal power play exposed weaknesses the Canadiens managed to hide against Tampa Bay.
The biggest concern for Montreal heading into Game 2 is not simply the series deficit. It is the realization that Buffalo appears built to punish every small mistake with terrifying efficiency.
The Sabres struck quickly in Game 1 and never truly allowed the Canadiens to settle. Josh Doan capitalized on an early defensive breakdown after Lane Hutson lost an edge, Ryan McLeod doubled the lead, and Buffalo’s power play added two goals in a performance that stunned a Montreal team expecting a tighter, lower scoring battle.

That statement may define the series.
The Canadiens survived Tampa Bay by staying structured, disciplined, and opportunistic. Against Buffalo, however, every turnover in the offensive zone instantly became a dangerous counterattack. The Sabres looked faster, more aggressive, and far more comfortable playing at high speed through the neutral zone.
Nick Suzuki admitted Montreal essentially “shot ourselves in the foot” during the opening stages of the game. The Canadiens trailed by multiple goals for the first time this postseason, and they looked rattled by Buffalo’s relentless pressure.
That pressure starts with Buffalo’s emerging core, which suddenly looks ready for a legitimate Stanley Cup push.
Rasmus Dahlin continues to dominate all over the ice, Bowen Byram is producing offense from the blue line at a historic pace for the franchise, and Ryan McLeod has become one of the postseason’s most disruptive two way forwards. Alex Lyon also gave Buffalo stability in net with 26 saves, frustrating Montreal during several key moments in the third period.
Perhaps the most alarming development for Montreal was Buffalo’s power play finally coming alive.
The Sabres entered Game 1 struggling badly with the man advantage, converting only once in their previous 46 opportunities. Then suddenly, against the Canadiens, Buffalo buried two power play goals in one night and looked dangerous nearly every time it gained possession in the offensive zone.
If that trend continues, this series could shift dramatically in Buffalo’s favor.
The Canadiens did show signs of life late in Game 1. They dominated puck possession in the third period, outshooting Buffalo 11-1 during one stretch while desperately attempting a comeback. Kirby Dach provided energy, Suzuki continued battling, and Montreal’s top lines finally established offensive zone time.
But even then, Buffalo never appeared overwhelmed.
That composure reflects how much this Sabres team has evolved under Lindy Ruff. Buffalo is no longer simply a talented young group happy to end a playoff drought. This roster now believes it can control games against elite opponents.
The Sabres already eliminated the Boston Bruins in the first round and finished atop the Atlantic Division during the regular season. Their confidence has only grown stronger with each playoff victory during the NHL Stanley Cup Playoffs.

The Canadiens entered the playoffs with little pressure and shocked many observers by eliminating Tampa Bay. Suddenly, expectations changed. Buffalo’s dominant stretches in Game 1 exposed how inexperienced parts of Montreal’s roster still are in handling momentum swings against elite playoff teams.
Cole Caufield remains quiet offensively. Rookie Ivan Demidov is still searching for his first postseason goal. Jakub Dobes looked human after an outstanding first round performance. Even Hutson, who dazzled against Tampa Bay, endured one of his roughest nights of the postseason.
Still, St. Louis refused to sound defeated.
The Canadiens coach emphasized that his team has responded well after losses throughout the playoffs and insisted Montreal can adapt to different styles. That optimism has defined his coaching tenure, helping transform the Canadiens from rebuilding project into legitimate postseason threat.
Elsewhere around the league, the Maple Leafs continue reshaping their future after major front-office changes, while projected superstar Gavin McKenna remains the center of NHL draft speculation.
Game 2 suddenly feels enormous.
If Buffalo wins again, the Sabres will head to Montreal with complete control of the series and growing belief that this playoff run could become something special. For the Canadiens, another defeat would reinforce the harsh reality St. Louis already understands: the Sabres are no longer an up and coming team.
They are a legitimate powerhouse, and they are playing like one.
Fans looking to watch NHL playoff games live are already circling this series as one of the postseason’s fastest rising rivalries.
