The Penguins need to fill the hole on the power play left by the departure of Phil Kessel. The addition of forwards Alex Galchenyuk, Brandon Tanev and Dominik Kahun will help provide offensive depth. The biggest challenge facing the Penguins will be defense. The Penguins defense led the league in number of odd man rushes allowed last season. The early injuries to centers Evgeni Malkin and Nick Bjugstad will severely derail any plans for a fast start. Losing the number 2 and 3 centers would hamper the most talented team. The Penguins will just make the playoffs.
