But on Saturday Brandon Prust, Travis Moen and Ryan White were the difference in Montreal's 3-2 victory over the Buffalo Sabres.
"It's good for us to chip in," said Prust, whose third goal of the year put the Canadiens in front 1-0 early in the second period. "Those top guys have been carrying a heavy load lately, and have been doing a great job. We want to contribute when we can. We were happy to do it tonight."
Prior to the game, Prust, Moen and White had a combined nine points on the season. On Saturday, they registered five of the team's nine points, and finished with eight hits, two blocked shots and no giveaways.
"We know what we're going to do out there the three of us," said Prust. "We're going to keep it simple, chip in pucks and support each other. We're good at protecting pucks. That's the key to our success."
After an uneventful first period in which neither team generated much offence, Canadiens coach Michel Therrien rewarded the fourth line by starting them in the second period.
"There was a message. We liked their intensity in the first period," said Therrien. "I don't think we had the right attitude to start the game. Those guys were intense."
Their line responded instantly, scoring 19 seconds into the period.
Prust started the play when he stole the puck from former Canadien Matt D'Agostini at the Buffalo blue-line before dishing it off to Moen. Moen quickly passed it to White, who completed the tic-tac-toe by feeding Prust in the slot.
After Tyler Ennis evened the score later in the period Moen drew two Sabres' players towards him, leaving Prust all alone behind the net. Moen slid the puck to Prust, who waited patiently for Tomas Plekanec to walk into the slot. Plekanecs' shot off the post and in at 17:44 put the Canadiens ahead for good.
"We get our success from putting pucks on net, playing that gritty type of game, getting to the net," said Moen. "It's always nice to pitch in offensively, get some points, and feel good about yourself. Tonight was that night."
Prust finished the game with a goal and an assist, Moen had two assists and White finished with one assist.
"They were practically our best trio," said Therrien. "They played a huge part in our team's victory. They created some scoring chances with their intensity. They spent a lot of time in the offensive zone. They certainly were true leaders tonight those three guys."
Therrien also complimented White's effort, suggesting he played his best game of the year. White has been in and out of the lineup for the Canadiens recently, sitting out six games as a healthy scratch since the start of the season.
"The biggest battle for me right now is for me to keep my confidence, not second guess myself," said White. "I'm chomping at the bit every time I can get in there.
"I felt good. My line played well, made it easy for me. I just felt like I was really into the game, ready to go every time I got a chance to go out there."
The only goal the fourth line wasn't involved in was Alex Galchenyuk's game-winner, which he scored at 18:07 of the second period, only 23 seconds after Plekanec's.
The Sabres responded with pressure in the third, and rookie forward Zemgus Girgensons reduced the deficit at 4:04 after a great individual effort saw him control a bouncing puck, go around Canadiens' defender P.K. Subban, and beat Carey Price by poking the puck into the net.
The goal was a silver lining for coach Ted Nolan's Sabres, which have now lost six straight road games and are last in the NHL with 14 points and a 6-22-2 record.
"He played well," said Nolan of 19-year-old Girgensons. "I've known the kid now for three years and have watched him play, he does this all the time. It's one of those things that comes with maturity, he'll get better and better.
"Those are the building blocks with which we're going to turn this organization around. It's through people like that, with some strong character and will to get better."
With the win, Montreal extended its win streak to five games and retained top spot in the Atlantic division. The Canadiens have only lost once in regulation time in the last 14 games and have not allowed more than three goals in any game during that time.
"Before playing this stretch, I won't lie to you, it scared us," said Therrien. "We should be very satisfied."
Jhonas Enroth, who got the start in net in place Ryan Miller, made 16 saves for the Sabres.
Price stopped 23 shots for Montreal (19-9-3). He is second in the league with a .938 save percentage and hasn't allowed more than two goals in his last nine starts.
