"I think you have to," Cole said. "It's one of those things where if you think about it too much, you're going to get way too excited. I know I would. You have to sleep. If you don't sleep, then you're not going to be as good come game time. So, it's one of those things where you have to try to keep it as normal of a routine as you can."
Before Game 7 of the Eastern Conference Final against the Tampa Bay Lightning, Pittsburgh stressed treating it as any other game. That turned into a 2-1 win on May 26.
It will be more difficult for the Penguins to rein in their emotions Thursday, but they know it's necessary.
"I'm not going to lie to you. It's not easy to think of [Game 5 as just another game]," forward Eric Fehr said. "That's what we have to do. We know this is going to be a tough game. We know the last one's the hardest to win and we know we have to be prepared for a battle."
Though remaining calm could prove challenging, the Penguins are confident in their structure. Their forechecking, speed and shot blocking will remain intact, which could help them settle in Thursday.
"I think we've played well defensively," said forward Chris Kunitz, who won the Stanley Cup in his first season with Pittsburgh seven years ago. "We've played as a good group that comes through the neutral zone with speed and puts pucks in behind them. We haven't really frustrated ourselves with not shooting the puck, and have kept a level head."
In possibly the Penguins' final practice of the Stanley Cup Playoffs, Sullivan skated his players for close to an hour Wednesday. Forward Nick Bonino, who took a maintenance day, was the only absentee from the lively skate.
