There's no denying the talent or explosiveness of the Penguins.
Heck, when your second best player would arguably be the best player on almost any other team in the league, you've obviously got talent. Geno is one helluva hockey player, and to think that his best years are ahead of him is scary.
That being said, I do think the Bs have a shot. In no other major sport is the truism "defense wins games" more applicable than playoff hockey. The Pens have 2 questionable goalies(although one has the hot hand now, and a hot goalie can win series for you). Their D is also suspect.
Their O is so potent, however, that their O becomes their D by occupying their opponents attention so much.
Still think we have a shot, though. While the Senators play much like us, they made one hell of an injury-riddled run for the last month and a half of the regular season, and first round of the playoffs, so they were spent.
The Bs coasted for the last month and a half and have turned it on at the right time. They have a chance.
