Yes it can be but The Sens have all right people in place from the GM down. The coach comes from a winning organization, they have the longest serving captain in The NHL, the team is finally being built around Spezza and he has been at his best since they made that turn, you still have Phillips and Neil there... so many things to protect the young players.
Also, coming up you have guys that were the captain of their NCAA teams in Greening, Condra, Boroweicki, and guys that will always work hard in Smith, Foligno, and Michalek.
The big question mark is Filatov for sure, if they did trade for Penner he would obviously be a question mark but would still instantly be a 20 goal guy on a team that will probably struggle to score.
All things considered it would be a smart move to pick up Penner if Murray truly believed he could be a kog in the offense for 3 or 4 years. If things don't work out with imidiate results he will be someone you could probably trade at the deadline anyways... that cup ring is huge.
