Wow. I thought the Pens had too many defensemen, but it would seem that Ray Shero may be psychic.
This will be a great chance for the defense to grow up fast without two of their top 4 for an extended period of time. I see this as very similar to the Crosby injury last year - it will force everyone else to pick up their game.
Here are the top 7 on the blue line (in no particular order):
You know, that's still a pretty strong lineup. Probably a bit lacking in offense, but they certainly have the toughness and speed.
