Jeremy Swayman gave Marco Sturm the backbone Boston needed to turn a retool year into a playoff return nobody saw coming.

That is the cleanest Bruins angle now. Boston did not get here on hype or one hot week. It got here because too many parts clicked at once after a dreadful 2024-25 season.

Sturm deserves a lot of that early credit. In his first year behind the bench, he got a roster that looked thin on paper to buy into a real push instead of drifting into another lost spring.

The belief inside the room mattered. Morgan Geekie said the Bruins always felt this could be a goal, even if the outside expectation dropped after last season.

Swayman is still the name at the center of it. His 42.1 goals saved above expected are 3rd most in the league, and his 0.8 mark per 60 minutes gave Boston the kind of nightly stability playoff teams need.

The bigger change is consistency. Swayman has saved more goals than expected in 41 of his 53 starts, and his quality-start rate jumped to 77.4 after sitting at 59.6 last season.

“It’s the combination,” Sturm told reporters about the second line’s ability to generate offence off the rush. “When you talk about entries, that’s what they bring. They switch it up, too, which is what makes them so dangerous. And now they know each other.

They’re good at it now. They’re comfortable. They talk a lot. They know where everyone’s at in any point of the game.”

The real reason the Bruins are suddenly a playoff threat and nobody saw this coming

That is why this turnaround feels real. The Bruins did not lean only on goaltending and hope for the best.

They built one of the league's more balanced attacks. Boston has 8 players with at least 15 goals, tied for 2nd most in the NHL, which makes them much harder to key on than a one-line team.

Geekie leads the group with 38 goals, and the second line has become a real problem. Pavel Zacha, Casey Mittelstadt, and Viktor Arvidsson have outscored opponents 21-11 at 5-on-5 since the Olympic break.

Then there is David Pastrnak, who changed the look of Boston's offense by becoming more of a creator. He sits on the edge of a 4th 100-point season and already has a career-high 70 assists.

That passing detail matters. Nearly 28 percent of Pastrnak's offensive-zone pass attempts have gone to the slot, and 50 of his 70 assists came off those passes into danger.

Charlie McAvoy and Hampus Lindholm getting back healthy gave the blue line a steadier frame too. Boston stopped looking like a patchwork team and started looking like one that could handle real games again.

Now the Bruins head into the playoffs as an underdog with a real puncher's chance. Balanced scoring can travel, a hot goalie can tilt a series, and Sturm has already pushed this group far past where most people thought it could go.
