Smith scored two goals against the Avalanche, one on the power play and one after coming out of the penalty box. Fiala scored a power-play goal and had an assist, and Turris had one assist. Their even-strength play as a line was not where they wanted it to be.
"We need to be better," Turris said. "Obviously we want to be contributing and making an impact. We've got to do a better job come second round here."
The Predators host Game 1 at Bridgestone Arena on Friday (8 p.m. ET; NBCSN, CBC, SN360, TVAS).

Nashville coach Peter Laviolette tried to shake things up to begin Game 6. Fiala started on the fourth line with Mike Fisher and Miikka Salomaki, and Calle Jarnkrok started with Turris and Smith. Laviolette eventually switched Fiala back with Turris and Smith.
"We've got to be better, especially me," Fiala said. "It's not good enough. I can't accept the game I played in the first round. I've just got to be better."
The Turris line was productive for the Predators during the regular season. Smith had 51 points (NHL carrer best 25 goals with 26 assists) in 79 games; Fiala had 48 points (23 goals, 25 assists), each a personal NHL high, in 80 games; and Turris had 42 points (13 goals, 29 assists) in 65 games with the Predators after being acquired from the Ottawa Senators as part of a three-team trade with the Colorado Avalanche on Nov. 5.
"I think if we just get back to what we were doing great before, loosen up and have some fun," Smith said. "I think when we're sticking together, we're close to each other out there, and especially when we're communicating to each other, I think it kind of holds each other accountable to be at certain places and support each other. I think that support is huge. That will be a big key to possessing the puck and using our speed."
