DALLAS — Claude Julien was happy about a lot of things following Saturday night’s 7-3 win over the Stars at American Airlines Center.

The Bruins coach was pleased about completing a season-long road trip with a 4-2-0 record. He liked how his team rallied from a 3-1 deficit, including two reviewed goals, to pour six straight pucks into the Stars net. He was satisfied to see his power play, 0 for 19 during the five previous games, punch through three times on six opportunities.

But Julien was perhaps most content with his team’s defensive play in the third period. After 40 minutes, the Bruins were only up by a 4-3 score. The offensively flammable Stars, led by Jamie Benn and Tyler Seguin, were well equipped to pour on the gas once more.

Instead, the Bruins put the game on lockdown. In the third, when the Stars should have pushed their hardest, the Bruins held a 13-9 shot advantage. They slammed down on the Stars on the forecheck, regularly sending two forwards deep into the offensive zone. The time and space the Stars once had was gone.

“We talked about putting pucks in deep and really forechecking hard, not to let them come out too easily,’’ said Julien. “In our own end, it was about closing quickly, getting pucks out, and getting pucks in. What you saw in that third period is that a lot of times, we just chipped pucks out to the neutral zone as best we could and we were willing to battle there. When you have the lead, you can play that way.’’

The rally started in the second period because the Bruins started to win battles in the blue-collar areas along the boards. At 13:24, with Vernon Fiddler in the box for high-sticking David Pastrnak, Brad Marchand snapped a long-distance shot past Kari Lehtonen. Jimmy Hayes did the dirty work in front by screening Lehtonen. But before the goal, Marchand performed the heavy lifting by winning a puck battle on the wall against Cody Eakin and Jason Demers.

The Bruins tied the game at 13:59. Pastrnak helped win a battle behind the Dallas net, which allowed the puck to get back to the point. Kevan Miller’s floater from the right point bounced in the slot and skipped past Lehtonen.

The Bruins pulled ahead for good at 19:08.Dennis Seidenberg rimmed the puck into the offensive zone. Johnny Oduya tried to pull the puck off the wall. But David Krejci, who had sprinted into the zone, overwhelmed Oduya on the forecheck. Once Krejci gained control of the puck, he saw Loui Eriksson open in front. Krejci’s pass thudded off Eriksson’s right skate before the left wing swept the puck under Lehtonen, giving the Bruins a 4-3 lead. Video review allowed referees Francois St. Laurent and Jean Hebert to call it a good goal, even though both had lost sight of the puck.

It was the fourth time the NHL’s war room was involved in the game. The referees racked up big-time long-distance charges with their repeated calls to Toronto. St. Laurent and Hebert spent more time looking at a screen than skating around the ice.

The barrage of video reviews started at 15:44 of the first period when Antoine Roussel tipped Oduya’s shot past Tuukka Rask. The first review concluded Roussel’s stick was under crossbar height. The second review took place when Julien challenged the goal, contending that Roussel had interfered with Rask. Roussel bumped Rask’s left skate as the goalie tried to catch Oduya’s shot. The goal was upheld when the referees ruled no interference had taken place.

Another review took place at 16:28. Patrick Sharp got behind Adam McQuaid and fired a shot on net. Rask stopped the shot, but as he reached back to keep the puck from crossing the line, a backchecking McQuaid knocked the net off its pegs. Video review showed the puck would have gone in off McQuaid had the defenseman not dislodged the net.

The Stars were flying. The Bruins couldn’t do much to slow them down. The reviews didn’t help.

“There were times in that first period where they had us hemmed in our own end for more time than I would have liked to have seen,’’ Julien said. “But just the fact that we kept sticking with what we had to do here. Eventually, we started winning battles. We started putting more pucks to the net. We were getting there first and had the rebounds and the screens. I think we realized pretty quickly what we had to do to win a hockey game. It just carried on from there.’’

The Bruins’ third-period offense complemented their defense. Krejci scored on the power play. Brett Connolly flipped a puck into the empty net. Matt Beleskey capped the onslaught with another power-play goal.

“This was really important,’’ Krejci said. “It’s a big difference going back [home] 3-3 or 4-2. Big win. But we’ve got another game in two days.’’
