Bob has made quite a transformation this season from a rookie goalie trying to find his way in the NHL to a playoff starter for a team poised to make a deep run. This afternoon we also learned of another transformation, one away from the Top Gun/Independence Hall/Liberty Bell motif to the straight-killer Rocky Balboa/Sideshow Bob look.
Here's what Sergei Bobrovsky's new playoff mask looks like, courtesy of CSN's Sarah Baicker. Yes, that's Sideshow Bob from The Simpsons.
The front of the mask appears to read "BOBS," while the side opposite of Sideshow shows two images of Rocky Balboa. I believe that is an image of Rocky holding the flag after beating Ivan Drago in Rocky IV in the fight that ended the Cold War.
