I think the Penguins Senators series is going to go the whole way, Ottawa were good last night. They managed to stop Crosby, and just did the little things right, and it worked for them.
I hope that the experience of most of the Pens players will win them this one though, there's quite a few guys on the Ottawa team who aren't used to the pressure of the playoffs. It didn't show last night of course, so I may be wrong.
