James Hagens impressed Marco Sturm as the Boston Bruins rookie spoke out after his first NHL game at TD Garden.

“It's definitely different when you're wearing the Bruins jersey. The fans are amazing, how loud they get out there. It's something I've never seen before, so that's really cool.”

That quote travels fast inside a locker room. Veterans hear it. Coaches hear it. It tells you the moment isn't too big.

Hagens has 1 point in 2 NHL games. But that's not the story driving this decision.

Sturm didn't park him at the end of the bench. He rolled him into regular shifts, not just sheltered minutes.

That's a coaching call with weight, especially this close to puck drop in the playoffs.

And now it carries straight into a first-round matchup against the Buffalo Sabres.

Bruins rookie James Hagens gets major playoff trust from Marco Sturm

The Bruins wrapped the season with 100 points and slid into a wild card spot. There's no runway left for development.

Hagens brings pace through the neutral zone and pushes defenders back on controlled entries. That stood out right away.

He doesn't hesitate with the puck. If there's a lane, he attacks it.

That element has been missing at times in Boston's middle six, where the game can slow down.

Sturm is reading that and adjusting on the fly. That's not typical for a rookie stepping in this late.

But playoff hockey punishes mistakes fast. Defensive zone coverage, faceoffs, and tracking through the slot become everything.

Hagens hasn't been through that grind yet. Not at this level.

Still, the Bruins aren't playing it safe. They're looking for a spark against a Sabres team that finished with 108 points.

Buffalo can skate. They can stretch the ice and force turnovers if you hesitate.

That's where Hagens becomes interesting. His speed can match that pace, not just react to it.

And if he can hold his own away from the puck, his minutes won't shrink.

They'll climb. Coaches reward players they trust shift after shift.

Boston's forward group suddenly has a different layer. Not just structure, but a bit of unpredictability.

That matters in a playoff series where matchups tighten and space disappears.

Hagens already showed he's not overwhelmed by the stage. Now it's about handling the details.

If he does, the Bruins may have found more than a late-season call-up.

They may have dropped a rookie right into a playoff role and stuck with it.
