Is Ottawa the Cup favourite after the big trade today?

Ottawa adressed big needs today with the additions of commodore and stillman, and top six forward and and stabilizing force on defense. Corvo was too risky and i think he would fit in better as an NHL forward. Also it looks like Emery's starting to finally get in to game shape as he gets ready for another long playoff run. Emery looked fantastic against Montreal on Saturday. No line in the league this year has been as good as Spezza Alfredsson and Heatley, the three players who finished tied for the league lead in playoff scoring last year. The defense is deep and experienced and they added a few cup rings. Are the Ottawa Senators the Stanley Cup Favourite this year?
