The Penguins have signed Jordan Staal and Kristopher Letang. Both will be on the roster for opening night. Both are aware that they may only be here for 9 games. Hopefully both stick longer, because that means that the Pens will be confident enough to carry them on the roster all year. I think, however, that both will be back in juniors in a few weeks.
Let's enjoy watching them while they're here.
