Even thought Pie is my favorite blue (yes mancrush) I think Pie need another season like this to get recognize world wide as the face of the Blues.
At the risk of sounded arrogant, I'd like to think that most of us are a bit ahead of the curve in such matters. I think you are right, Pietrangelo will likely be the face of the franchise by the end of next season, but he isn't there yet.
Backes is the current face of the franchise. He's nominated for an award, commentators always mention him first, and he's been the leading scorer for the last two seasons. Pietrangelo will become the face once he gets more Norris recognition, but for now? It's Backes.
Jaroslav Halak,he's very underrated and fans in general don't see his true value. I was disappointed to see him injured in the playoffs because he was ready to show the world that he can bring a cup for the Blues.
He's the type of goalie that makes a impact when the team is down and out.
