Boston's fourth line was immense in the loss, putting together their most effective all-around performance of the season. With Sean Kuraly shifted to the left side and Noel Acciari back in the lineup at center, the trio was dominant at times in the offensive zone, while also bringing their usual energy and snarl.
The line combined for 14 hits and four points, while Wagner landed a game-high nine shots on goal, including his third goal of the season to bring the Bruins within 3-2 at 7:08 of the third.
"We've got to play like that every night," said Wagner, who also added an assist on Carlo's goal. "We got the puck in, we dominated down low, and it feels good for our line personally…I thought we played a good game, created a lot of havoc and momentum for our team."
Acciari was back in the lineup after sitting out the last three games as a healthy scratch. And with Kuraly coming off minor nose surgery that required him to wear a full shield, Cassidy thought it was best to shift him to the wing.
"We weren't sure how he'd be…if playing with the facemask was gonna throw him off down low," said Cassidy. "I like Noel in the middle, always find him responsible, allows his wingers to go and work. Sean was much better offensively it seemed without having to worry about the other end as much, getting back.
"So maybe we found something there, but they got rewarded, they played real hard and we need the secondary scoring."
The triumvirate thought they had another goal in the second period with the Bruins down, 2-0, but an early whistle negated what would have been Kuraly's second of the year. Wagner took the puck to the net and was shoved into Pittsburgh goalie Casey DeSmith. With the puck sitting on DeSmith's chest, Kuraly came in and knocked it into the net, but after review the call of no goal on the ice stood.
"They said he just blew the whistle, he lost sight of the puck," said Cassidy. "Can't argue that…once they blow the whistle, there's really no challenge on my end."
