Gone are the days when an NHL coach has to tap an enforcer on the back and let him know it’s time to change momentum.

Nowadays, those guys can sense when they need to provide a shot of energy by a well-timed heavy hit or a hefty haymaker.

“I don’t think that ever really happens anymore. I think it’s always just kind of a feel thing for guys on the ice, feeling the intensity, emotion of the game,” said Tanner Jeannot following the Bruins’ morning skate Tuesday. “Maybe I’m wrong, but it’s never happened in my career.”

Jeannot and fellow heavyweight Mark Kastelic dropped the gloves and swung the momentum in the 4-3 shootout win over the Blue Jackets in Columbus Sunday night.

With the Bruins scuffling and trailing, 2-0, the 6-foot-2-inch Jeannot went toe-to-toe with 6-5 Erik Gudbranson in a spirited and lengthy bout, with Jeannot scoring a victory.

Get Starting Point

A guide through the most important stories of the morning, delivered Monday through Friday.

Just six seconds later, the 6-4 Kastelic exchanged some thunderous hits with Mathieu Olivier, widely considered the top pugilist in the NHL. Kastelic gave as good as he got in a pretty even battle — though rumor has it Derek Sanderson scored it for the guy in Black and Gold.

Though the Bruins fell behind, 3-0, moments later, the tide had turned. Boston was the better team for the final 45 minutes, plus the shootout.

It all started with the fourth-line fireplugs igniting their teammates.

“It was huge,” said Kastelic. “Give credit to a lot of guys, Jeano, and then for everybody to just rally after the first period. It was incredible. For us, you could just feel us get stronger as the game went on. Once we tied it up there, that was huge just to get the 1 [point], but to get the 2, that was the cherry on top. It was a complete team effort, per usual. I think it starts with Jeano to get everybody going. It’s something we can build off.”

The fights were organic.

“Nothing was planned, no, it just happened. It’s easy to have a lot of courage when I see a guy like Tanner do what he did there, and I definitely fed off it,” said Kastelic.

Jeannot was equally effusive in his praise of Kastelic for taking on one of the league’s toughest customers.

“[Olivier’s] got to be one of the toughest, if not the toughest guy in the league, and it takes a lot of guts to stand up to a guy like that,” said Jeannot. “Kasty’s been doing it all year. He’s the heart and soul and he gives everything for us every night. It doesn’t surprise me that he stepped up. You’ve got to show respect for that and give everything you’ve got for a guy like that.”

Long road

The win in Columbus was the sixth straight road game in which the Bruins collected at least a point and raised their record away from friendly confines to 15-14-7. Boston is over .500 on the road for the first time since Opening Night … The Bruins start a four-game trip Thursday in Sunrise, Fla., followed by stops in Tampa (Saturday), Philadelphia (Sunday), and Carolina (Tuesday).
