Lucic and the red-hot Bruins look to extend their winning streak to eight when they conclude their season series with the Penguins on Saturday night.
Boston (38-19-7) is enjoying its longest streak since a 10-game run from Dec. 12, 2008-Jan. 1, 2009.
The Bruins received a dose of good luck in Thursday's 2-1 win over Southeast Division-leading Tampa Bay. Lucic broke a 1-1 tie with 3:42 to play after gathering a puck that deflected off a referee's skate and flipping it over a pile of players in front of the net.
Boston has outscored the opposition 22-10 during the winning streak, which has helped it build a six-point cushion on second-place Montreal in the Northeast. The Bruins are just three points behind Eastern Conference-leading Philadelphia.
"I like the attitude right now," coach Claude Julien told the team's official website. "We have a group of guys that seem to be very business-like people who want to accomplish things.
"They want to go through the grind of wanting to do it and they're willing to do it on a nightly basis right now. You just have to make sure you hang on to that."
Lucic has been key over the last seven games with five goals and four assists. He has a team-high 28 goals -- six shy of the total from his first three NHL seasons.
Tim Thomas and Tuukka Rask, though, might be making the biggest impact during the winning streak. Rask has won four games with a 1.75 goals-against average and one shutout, while Thomas has given up just one goal in each of his last three starts after stopping 27 shots versus the Lightning.
It's unclear who will be in net Saturday, but Thomas is 2-0-1 with a 0.65 GAA over his last three home starts against the Penguins (37-21-8). He stopped all 27 shots faced in the Bruins' 3-0 home win on Nov. 10, 2009.
Rask made 33 saves in a 3-2 loss to Pittsburgh on Jan. 15, falling to 1-2-0 with a 2.69 GAA in three career starts.
While the Bruins are surging, the Penguins in a 3-6-4 stretch as they continue to play without high-scoring Sidney Crosby and Evgeni Malkin among others due to injury,
"The bottom line is things haven't gone our way so we are going to keep building off it and keep going and eventually we'll be able to get out of the little funk we are in and start winning these games," center Michael Rupp said.
Marc-Andre Fleury will likely be in net, and he's won each of his last two visits to Boston with one shutout. He made 44 saves opposite Rask on Jan. 15.
Fleury, however, has a 3.48 GAA while losing four of his last six on the road.
The Bruins' Mark Recchi is expected to play in his 1,636th career game, moving ahead of Hall of Famer Scott Stevens for sole possession of sixth in NHL history.
Boston, however, will be without leading scorer Patrice Bergeron as he deals with a personal matter.
