In case anyone was wondering whether the Bruins were still an elite team, this holiday weekend was a pretty good barometer.

And the B’s answered that question affirmatively.

On Sunday, they had to contend with the speed and explosiveness of the Chicago Blackhawks and came away with a point in the shootout loss. They very easily could have won that game.

And a little more than 24 hours later at the Garden yesterday, the B’s faced the bruising Los Angeles Kings. The result was a black-and blue 3-2 victory that pushed them back into the Atlantic Division lead by two points with a game in hand on the second-place Lightning.

Less than two weeks ago, coach Claude Julien was trying to get his team back on track after it lost consecutive games in Anaheim and LA. But he was understandably feeling pretty good yesterday.

“I’ve got to be honest with you, I’m pretty impressed with our team and the way we’ve handled these last three games, actually,” said Julien. “We had a good start in Dallas (on Thursday) and (Sunday) was one of those great games that as a fan you like to see. Wish we could have had that extra point.

“But to come out there today and play an afternoon game and play a real good team that plays a heavy game, is one of the elite teams in the league and was waiting for us here, I thought our guys did a great job of having a good start. I thought it was important to let them know that we were ready to play.”

Making yesterday’s performance even more impressive was the fact that the B’s were playing with a very green blue line. They started the game with four defensemen who had a combined total of 120 NHL games to their credit — Matt Bartkowski (53), Torey Krug (51), Kevan Miller (15) and Zach Trotman (one) — and they received some big contributions from the youngsters.

Krug scored his 11th goal of the year on the power play — courtesy of a Zdeno Chara screen — while Miller played a very gritty game, notching a game-high five hits, including a couple of bone-crunchers on LA captain Dustin Brown, who is usually the one lowering the boom.

“The young guys, you have to give them props,” said Patrice Bergeron. “They handled themselves like veterans out there.”

But the first star of the game was the resurgent Brad Marchand, who scored two more goals yesterday — including the game-winner — after notching a pair against the Blackhawks. After struggling terribly at the start of the season, Marchand now leads the team in goals with 16.

His first of the day was a brilliant shorthanded play. Operating one-on-one against Drew Doughty, Marchand knocked the stick out of Doughty’s hands with one of his moves and went around him to get a shot off that Jonathan Quick stopped. The puck eventually came back to him and he then faked out one of the best defensive forwards in the league, Anze Kopitar, to get a clear shot on Quick, and he scored through the 5-hole at 12:07 of the first.
