The Red Wings' power play finished the game 2-for-5 after scoring one power-play goal through the first five games of the season.
"We just weren't good defensively. We needed to be better on the power play, and I thought we did that," Bertuzzi said. "In five-on-five, we needed to bear down a bit more."
Givani Smith and Taro Hirose were called up from the taxi squad prior to Sunday's game and each made their season debuts. The Red Wings also announced that Riley Barber was added to the taxi squad from the Grand Rapids Griffins.
Game one of the Dallas series will begin at 8:30 p.m. on Tuesday. The Stars were the Western Conference representative in the 2020 Stanley Cup final in Edmonton, and had the start of this season delayed due to COVID-19 protocols.
As Larkin alluded to, and according to Bertuzzi, the Red Wings will need to mentally move past the pair of losses in Chicago as soon as possible.
"A short memory is a big key to this season," Bertuzzi said. "Forget about it and move on to the next series, and try and get better every night."
