"It's going to be a challenge for Anaheim to deal with that in the series. Getting the Predators defensemen active without them getting caught, that's a big advantage for them."
Pearn said a concern will be the faceoff edge the Ducks often have.
"From a coach's perspective, Nashville lost too many faceoffs (56 percent) in Game 1," Pearn said. "Over time, that begins to work against you, and of course, it was a lost defensive zone faceoff that created the tie game for Anaheim in the third period. Early in the game, Anaheim dominated but Nashville did win faceoffs later that gave them possession.
"From a coach's eyes, that's one thing heading into Game 2 that they'll be talking about, looking at and trying to address."
Another element of the series was evident in Game 1 with how the Predators were able to sustain offensive zone time.
"Their cycle game is strong," Pearn said. "With all four lines they got good pressure and when they establish that cycle and pin Anaheim in, they're hard on them and that burns up minutes and stresses Anaheim's defense.
"One of the things Nashville does really well is keeping the defensemen wide on the rim for the cycle when they have good possession. That's really good position to be in but there is one risk, that when you give up possession, you can make yourself vulnerable. This could come into play down the road and Anaheim seemed to be aware of it and trying to split them up the middle with a long pass. That will be interesting for Nashville going forward, whether Anaheim will take advantage of that. They didn't [Friday] night."
Pearn said another factor that stuck out for him was back pressure by forwards on each team, a key reason why each has reached the Western Conference Final.
The head-to-head matchups will be another area worth watching as the series unfolds.
"As the game went on, Anaheim didn't seem as set on it," Pearn said. "They had Ryan Getzlaf's line against Ryan Johansen's line more than I thought they would, when I thought it would be Ryan Kesler's line against Johansen more. That's a bit interesting. It's one area that could turn out as a Nashville advantage, but it's really hard to say right now.
"I sensed a little concern in the [second round series] with Anaheim about their fourth unit. I think the fourth unit for Nashville had a bit better game and [Predators] coach Peter Laviolette felt more comfortable using them than what [Ducks coach] Randy Carlyle was using their fourth group.
"That's going to be interesting as we go on into the series, because it can cause top guys to play more and pick up extra minutes."
