For a guy that is SO bad, he's got 2 SC under his belt and a LOT of playoff time. Not seeing the Pens trade him to make room for prospects or to add a more skilled veteran. There aren't that many around that would fit this team or offer that much experience.
He's playing well--as well as Scuderi can play--and my guess is that management realizes his trade value is low but his playoff upside is high--aka, he's a veteran playoff leader that steps up in the post season, knows the grind of the playoffs well and is arguably one of the best PK D-men in the league. Scuderi won't give you any flash, but he'll take pucks and sticks to the face and ankles for 2 minutes on the PK in a playoff game to save the series.
Strong PK in the playoffs can't be overstated as the key to getting to and winning the SCF . Why would you trade a guy that does it so well and is a proven SC winner because of it?
Given that he's done it for this team before and their big guns have **** the bed a few times in the post season, I think he'll be in a Pens uniform into the post season.
