Kopitar, forward Dustin Brown and goalie Jonathan Quick of the Kings each is 4-0 in Game 7 in his NHL career.
"It's always nice to have that in your back pocket, but every game's a new game," Kopitar said. "I'm sure this one's going to have a few wrinkles in it. You go and play the game as hard as you can and see what the outcome is."
Nerves are real, Kopitar said.
"I still get jitters for Game 1 of the regular season," he said. "I'm sure there will be some jitters but once you get on the ice, you forget about all of that and just play the game."
McDavid, 0-1 in Game 7 in his NHL career, said he believes controlling the nerves, noise and emotions of the winner-takes-all game varies from player to player.
"If you're a guy that feeds off the crowd's energy, then you use it," he said. "If you're a guy that likes to keep it a little more quiet in your head, then quiet it down.
"It's going to be loud. Obviously we love our fans and we hope the building gets absolutely rocking and I'm sure it will be, but it's just hockey and we've got to go win a game."
