Trading Jordan Staal would be a foolish move. Stall is a great shut down center with the potential to be a great goal scorer. He has good size, throws hits, and rarely gets caught out of position.
Yes, finding the back of the net has seemed to be a challenge for him, but there is no denying that he puts up a solid performance every game. With such potential the Penguins just need to find the right players to put on his line, which should be second line center.
With lines always being put together and then separated, I have seen a lot of inconsistent play, aside from Malkin, Crosby, and Sykora. We need to give line combinations time to adapt to one another and get used to each others styles for more than one game.
I can't remember ever seeing Staal playing on the same line as Crosby except for maybe on the power play. Just because Staal hasn't had the offensive showing he did in his rookie year, doesn't mean that the Pens should trade him.
There is a lot to be said about having a good penalty killing defensive center, especially with the gaps in the Penguins defense, and lazy passes along the offensive blue line.
Bringing Chris Kunitz in from the Ducks was a good move for Shero, and seems to have been the answer for the lack of offense from Jordan Staal. If Bylsma keeps them together with Kennedy, which would be one of the hardest working lines in he NHL, we could see Malkin, Crosby, and Sykora together on a regular basis.
It would also mean that other teams would have to try and shut down two powerful scoring lines instead of one, which is what Penguins fans are used to seeing.
