Seven Penguins were on the roster against the Rangers in 2014: forwards Crosby, Evgeni Malkin, Chris Kunitz and Beau Bennett, defensemen Kris Letang and Olli Maatta, and goalie Marc-Andre Fleury. Five of those seven have played this series; Fleury and Bennett are injured.
"The past is the past," Sullivan said. "This is a new team, a new coaching staff, a new experience. We're taking each game as it comes. We understand that the elimination game is the most difficult one, so our intensity and our compete level has to be higher. Our attention to detail has to be better."
Rookie goalie Matt Murray, 21, was starting his career in the American Hockey League while the Penguins were losing to the Rangers in 2014. This time, he has allowed one goal in the past two games, including his first NHL playoff shutout, a 5-0 Game 4 win Thursday.
He said he doesn't think what happened in 2014 will play any role come Saturday.
"I've watched this team pretty much every game since I've been drafted here [in 2012]," he said. "That's in the past. We're going to try to stay present, stay in the moment and focus on the task at hand … It's going to be a heck of a challenge."
