Pittsburgh Penguins vs Nashville Predators prediction

NHL playoffs, big final the series is tied 2-2, best of seven games. The Penguins have won opening two games at home, but after that they failed twice in Nashville. Pittsburgh will be without few key players, Bonino, Letang, Hornqvist, Ruhwedel. They are mentally down at the moment. On the other side Nashville crashed twice at home their rival 5-1 and 4-1. It's very interestring that the Predators outshooted their rival in each of these four matches played so far. Nashville are in great form and I will trust them again.
