Keys to the first-round playoff series between the Anaheim Ducks and the Nashville Predators:
1. Center matchup: Nashville is one of the few teams that can match the Ducks down the middle. Ryan Johansen, Mike Ribeiro, Mike Fisher and Paul Gaustad will go up against Ryan Getzlaf, Ryan Kesler, Rickard Rakell and Nate Thompson.
3. Goaltending. The pressure is on Nashville’s Pekka Rinne to be the type of goalie that can carry a team deep into the playoffs. He is 15-19 in the postseason with one shutout. The Ducks need their duo of John Gibson and Frederik Andersen to carry over their fine regular seasons against the Predators, who are better offensively than years past.
