To anyone that thought the Bruins locker room chemistry would take a hit after adding Rick Nash, Brian Gionta, Nick Holden and Tommy Wingels during the trade deadline period, they’ve been sorely mistaken.

Not only have the deadline quartet been fitting in with their new teammates away from the rink, but they’ve quickly made themselves at home on the ice. All four have contributed at least one point over the recent pair of contests.

Their contributions took center stage Thursday night against the Pittsburgh Penguins. Wingels was the only one of the four held off the scoresheet against the two-time defending Stanley Cup champions in the Bruins’ 8-4 victory. Nash built off his first goal in Boston Tuesday night — in a 4-3 victory over the Hurricanes — by adding a goal and an assist, while Gionta earned a pair of assists and Holden added an assist of his own in their Black and Gold debuts.

“They’ve been playing good,” David Krejci said about the new additions after notching his first hat trick in four years. “I know it’s not easy but they fit in with everyone really well, so hopefully, they can keep it going.”

It certainly isn’t an easy thing for any of the new additions to fit in right away with a new club but Nash, Gionta, Holden and Wingels have made it look easy. It has been anything, but easy, both on and off the ice, however.

Thursday’s affair can attest to that theory as the two teams combined for eight goals on 21 shots in the opening 20 minutes. Not exactly the easiest game for anyone to get their feet wet, let alone Gionta and Holden in their first game with their new teammates.

“The first few shifts you’re trying — not so much to play it safe — to make sure you’re making the right decisions, and the right plays,” Holden stated following his first game since Feb. 18. “And once you feel out the game a little bit, you start to make a little more plays. The way our team plays, we play fast, so it’s a fun system to play in as a defenseman and it was a good game tonight.”

“Early part of that game was back and forth,” the former Boston College star Gionta assessed. “Everything was going in so I think after the first 10 minutes of the game, both teams settled in a bit, and obviously, we were moving pretty well tonight.”

Some of the new additions have had a little more time than others. Holden, acquired from the Rangers on Feb. 20, was the first addition in a deal that included Rob O’Gara and a third-round pick in 2018. Five days later, Don Sweeney acquired his biggest deadline piece in Rick Nash and sent the Blueshirts, Matt Beleskey, Ryan Spooner, Ryan Lindgren, a 2018 first-round pick and 2019 seventh rounder. Gionta signed his one-year deal moments after the Nash transaction, while Wingels came to Boston in a last-minute deal from Chicago for a conditional draft pick on deadline day, Feb. 26.

Thursday marked the first game that the quartet was on the ice together donning the Spoked B. For anyone that watched a Bruins game for the first time this year, one would think that the four were playing with their teammates for years.

Off the ice, the veterans have complemented their new peers, both old and new alike.

“Well they’ve fit in seamlessly,” Cassidy said. “You’ve got veteran guys that have been in other locker rooms. I can’t speak whether they’re good or bad or indifferent locker rooms — I know that ours is terrific when it comes to our leadership, and I think our young guys have helped it as well because they bring a lot of energy and they have a lot of personality, but they’re respectful; they want to learn from these veteran guys. So you get that mix in there and since they’ve been here [Gionta, Nash, Holden and Wingels] I think everyone has wanted to get in there and do their part, so they’re good people as well. It hasn’t seemed to disrupt anything.”

“It’s fine. All the guys that we have are experienced guys – guys that know what they’re supposed to do. The coaching staff has done a good job at making sure that they are ready and prepared, as far as the system,” captain Zdeno Chara added. “They are good enough players to make their reads and react on the ice, based on what’s going on. So good for them. We are very happy that they are playing well and helping us to play the way we are.”

Come June, Chara and company hope the deadline quartet can provide the final piece to the Cup puzzle.
