Tough call on Peks. After letting in six goals he might come out hungry to blank the next team, but then again he may already be slightly fatigued or he could not be feeling well (injury or illness... the flu has been going around the league a bit). It's a bad time to sit the best player on your team, but sometimes the best decisions are the hardest ones to make.
Personally, I start him if I'm Trotz. Coach should know what's going on if it's something other than him simply having a poor night. If the guy is tired Trotz is experienced enough to read that. Start him, see how he looks, and if he lets in a couple of bad goals put Lindback in. The Preds don't play again until Saturday anyway.
edit: FWIW
http://www2.dailyfaceoff.com/starting-goalies/ has Pekka as the likely starter
It also lists the lines as
Wilson - Legwand - Hornqvist
Erat - Fisher - SK
Spaling - Smith - Tootoo
Halischuk - Smithson - McGrattan
So there's that. Keep checking back to see if they confirm Rinne or change the lines
