They do because they've played so often together and had so much success, particularly last season and into the Stanley Cup Final. Palat said there is no adjustment time needed when Cooper taps them on the shoulder to go over the boards together because they know each other so well.
"When I'm on the ice with them, it's just automatic," Palat said. "I think it's just the confidence we have together. I know exactly where Kuch and Johnny are going to be. We trust each other. That's the biggest thing."
However, it doesn't mean Cooper is going to start Game 4 with the line intact.
The Lightning have gotten this far without having to tap into that safety valve often. Instead, it's been Alex Killorn on a line with Johnson and Kucherov, and Palat with Valtteri Filppula and Jonathan Drouin.
For two rounds and through Game 1 against the Penguins, that top-six forward group worked well and had combined for 57 points, including all three goals and six points in Tampa Bay's 3-1 win in Game 1 against Pittsburgh.
"When we're clicking and scoring goals it's good, especially with me, [Drouin] and [Filppula]," Palat said. "I think our four lines look good when we're playing the way we're supposed to play."
The Lightning have gotten thoroughly outplayed and outshot the past two games, which is why their top two lines haven't looked good and why Cooper went back to "The Triplets" for the third period in Game 3.
"You're trying to help, just trying to find ways," Cooper said. "Because it's worked with those guys in the past, we wanted to go back to it."
But again, this is a safety valve for him, so there's a chance he could start Game 4 with his original top-six forward group and adjust from there if need be. The hope would be that Killorn, Johnson and Kucherov would click again, and that Drouin, who struggled in Game 3, would find his game again with Filppula and Palat.
