Kastelic and Jeannot have a side fans rarely see

The Bruins' official account just shared what a teammate says about Mark Kastelic and Tanner Jeannot, and it's not what you'd expect.

Those two spend their nights banging bodies and making life miserable for the other team's fourth line. Apparently the locker room sees a very different version.

The teammate, who isn't named in the post, put it this way:

"They're two of the nicest guys on the team. It's kind of crazy how they can just flip the switch." He went on to say Kastelic is "the nicest guy I've ever met," so soft-spoken that "sometimes you can't even hear him."

Picture that for a second. A 6'4", 235-pound center who barely raises his voice in the room, then skates out and does the heavy lifting.

The teammate says Kastelic "cares about everybody so much," and that you see the same thing in Jeannot. That fits a player who dropped the gloves with Nicolas Deslauriers on October 27 and is, by all accounts, a good teammate the rest of the time.

Why the Bruins fourth line works

The numbers back up the role. Kastelic has 3 goals and 4 assists in 17 games, and he's a +3. Jeannot has 1 goal and 4 assists in the same 17 games, with a +5 rating and 30 penalty minutes.

That plus-minus matters on a fourth line. Nobody is asking these two to score 30, and a +5 tells you they're not getting hemmed in their own end either.

At practice, the lines had Jeannot, Sean Kuraly and Kastelic together. Kuraly has played six games this season and was drawn into the lineup at Pittsburgh on Thursday, a 6-2 win.

That group gets a real test this afternoon at TD Garden. The Panthers, coached by Paul Maurice, come in after a 4-3 loss in Washington last night, and a fourth line that wears down a defense can tilt a game like this.

Boston is 12-4-1 and sits first in the Atlantic, with a three-game winning streak. Marco Sturm's depth guys are a big part of that, whether or not you can hear them in the room.

Quick hits

CHICAGO BLACKHAWKSA players-only meeting after a 9-2 loss in Carolina. Nobody calls that meeting after a one-goal game, so the room clearly wasn't happy.

TORONTO MAPLE LEAFSGavin McKenna knew he'd probably sit after his mistake against Montreal. The Leafs didn't let him stew, and it's worth hearing what Jim Hiller told him.

PITTSBURGH PENGUINSSidney Crosby moved past Marcel Dionne into sixth on the NHL's all-time points list as the Penguins beat the Kings 5-2. Another name passed, and another one to chase.

CAROLINA HURRICANESJordan Martinook scored twice in the first 19 minutes, and the depth lines never let up on Chicago. That's how a 9-2 game happens.

DETROIT RED WINGSBlanked 4-0 in Colorado, the Red Wings now head to St. Louis on a three-game losing streak. The offense has to show up, and soon.
