"I'm sure early on, in the second period, Nashville is looking up at the clock and the score, they're down 3-0 for a while and kind of saying to themselves, 'How can this be?'" Pearn said. "I think in some ways it would have been a little bit of a negative drag. But it's a credit to them and it comes from the confidence they've developed earlier in the playoffs in their ability to come back.
"Certainly, a lot of teams in that situation would have lost their belief."
The Predators' third-period rally may have inadvertently brought a vulnerability to their game that cost them in the end, Pearn said.
"The thing about that fourth goal -- I've been part of games where this has happened, and it's part of the reason the NHL's stats are so skewed toward the team ahead at the end of the second period -- is that you work and work to get back in a game, and that was Nashville pressing, pressing in Game 1," Pearn said. "Then they got the two goals in the third to tie it and the sense on the bench is, 'Now we're going to win.' You want that feeling, but with that sometimes comes being a little bit overaggressive in certain situations.
"You sometimes slide out of the mentality that got you back into the game, like getting pucks behind the other team's defense and creating turnovers and drawing penalties."
Game 1 also produced plenty of talk about Predators goalie Pekka Rinne allowing four goals on 11 shots.
"It was a factor at times in the Western Conference Final, and [Penguins forward Jake] Guentzel's goal is one of those goals from an area that's probably just outside the prime scoring area but that's an area where Rinne has seemed a little bit vulnerable," Pearn said. "You can't say he hasn't been good in the playoffs, but he seems to be vulnerable on some of those outside shots when he seems to be not quite as set in the position he should be. Still Guentzel's shot was a pretty good one.
"Looking ahead, I don't think it's going to bother Rinne. He had the one game in the Anaheim series where he wasn't as sharp (allowed four goals on 26 shots in a 5-3 loss in Game 2), two goals that he probably wanted back, but he bounced right back so I expect he will again.
"On Monday, despite what appears in the stats, I don't think he had a bad game. It's part of the strangeness of how the game unfolded."
