But Babcock, whose eight-year contract runs through the 2022-23 NHL season, said Komarov (four goals in 46 games) and Polak (two in 27) bring an edge required for a defensive-minded system that is needed to have postseason success.
"We can move guys around if we feel it's going to help us get better," Babcock said. "I just think when I look at our last couple of games, I think that we're in a good situation. I don't feel like you (media) guys do, not one bit, but when I do, we'll change some things.
"I think, the better teams play defensively, the more you shoot to break them down. It creates more randomness rather than thinking pretty plays are going to be there."
Kadri has one point in 17 games, Marleau has none in six, Marner has two in eight, and Matthews has two in six heading into a road game at the Philadelphia Flyers on Thursday (7 p.m. ET; TVA Sports, NBCSP, SNO, NHL.TV).
"We've created a lot," van Riemsdyk said. "We have a lot of skill in here. There's a lot of ebbs and flows in a season. You have to find a way to win even when the puck isn't going in."
Asked why he thinks the existing lines should remain intact, van Riemsdyk said, "Just the familiarity with each other. Just working through it makes you that much better."
Marleau, in his first season with Toronto, won two Olympic gold medals with Babcock for Canada (2010 Vancouver, 2014 Sochi).
"He wants the best and expects the best," Marleau said. "You can call that stubborn if you want."
