Seguin, Benn and Radulov were producing in the first four games of the series, combining for 17 points (seven goals, 10 assists) to help Dallas get out to a 3-1 lead.
They've gone cold in the past two games partly because Dallas has had penalty problems. Colorado had five power plays in Game 6 after getting six in Game 5.
Dallas killed them all. Seguin, Benn and Radulov are not regulars on the penalty kill so their ice time gets shaved.
Radulov played 15:52 in Game 6; Seguin played 15:09 and Benn played 14:31. The ice time was 15:06 for Seguin, 13:26 for Benn and 9:31 for Radulov in Game 5.
"But that's no excuse at this time of year," Seguin said. "We've got to find a way to help our team."
They haven't, Bowness said, because they're out of sync.
"When they're on they're moving the puck, they're supporting the puck, they're reading off each other like every top line does," Bowness said. "We're not seeing any of that right now."
It's a missed opportunity too, because the Avalanche are using their third-string goalie, Michael Hutchinson, and the Stars aren't doing nearly enough to make his challenge of helping to keep the Avalanche alive in the playoffs difficult.
Hutchinson faced 28 shots in Game 6, stopping 27. He made 31 saves on 34 shots in Game 5.
"We preach as coaches to never pass up an opportunity to put the puck on the net, just don't," Bowness said. "If you get too cute, you're playing into their hands. We're making it an easier night on the goalie than it should be. … We've got to make the night a lot harder for him."
That has to start with Seguin, Benn and Radulov in Game 7. Colorado has the momentum, and teams that win Games 5 and 6 after trailing a series 3-1 are 29-28 (50.8 percent) winning a best-of-7 Stanley Cup Playoff series.
"It's on us to change," Radulov said.
It would change the narrative if they did, because right now it looks like deja vu for them and the Stars.
Seguin, Benn and Radulov also struggled last year when Dallas had two chances to eliminate the St. Louis Blues and advance to the conference final after taking a 3-2 series lead.
Instead, they combined for two points (one goal, one assist) in Games 6 and 7 and the Stars lost both.
"We all know what happened last year," Seguin said. "We were in this position, a chance to win it in Game 6 on home ice. I guess technically you could say tonight was home ice. We lost last year. We have a chance to redeem ourselves.
"I definitely do think as an organization we've been trending in the right way. This is the next step. It's going to be a big one for us in a couple of days."
