Honestly, here's how I see it.
First, the Pens generally paid better. The Pens also had many calls in favour of them.
The Sens for next game need to realize, crappy calls will be called, constantly. Its just how it rolls. They need to just play that much harder! They need to hit hard, shoot hard, and block tonnes. They need to take that "anger" from post game, and put it into productive clean hard hits, clean hard shots, in which someone is there for the rebounds, and some solid defence and goaltending. And those big name players need to do something.
While some of those calls are immensely frustrating, Sens need to take drive from it.
GO SENS GO!!!!
