It doesn't rank as high on the totem pole as shoring up the No. 1 goalie spot or landing a top-four, left-handed defenseman, but the Penguins will also need to identify a capable third-line center this offseason.
It'll likely take a handful of injuries to see Jeff Carter slotted up the middle on the third line at any point going forward, and although Ryan Poehling finished this past regular season playing in that spot, his ideal deployment would be on the fourth line with a good bit of action on the penalty-kill.
Beyond those two, the Penguins don't really have any in-house candidates to fill the role.
