They serve as a symbol of how far you've come in the world of hockey. Every team is in on it; it's a tradition. The act of growing a playoff beard has been a superstition among hockey fans and players for as long as anyone can remember. To grow the biggest, bushiest, messiest beard you can during the NHL Playoffs in hopes that once you reach the mountain top, you can enjoy the best shave of your life.
Here are some Rangers who show potential to grow some awesome fur in the upcoming playoffs.
Bushy and Rugged
Henrik Lundqvist

Unless
Vogue calls up with another offer for a photo shoot, I hope Hank grows out something for us Rangers fans to enjoy. It would be nice to see the potential for the man in net to grow out a big fluffy one if the Ragers can make a deep run in the playoffs. However, knowing Hank, the superstitious man that he is, if he feels it interferes even slightly in his play, he won't grow one. But as a treat for the fans, I hope we get the chance to witness gloriousness on top of gloriousness that is his face.
Brian Boyle

Not sure how much ice time the big man will get once the Rangers go to the playoffs, but I think the big guys got beard potential. We got a glimpse of what Double B can do with his facial hair in last years playoffs, but hopefully he can have enough time to grow it out so he can, you know, actually intimidate someone on the ice.
Dan Girardi

You don't block shots like Dan Girardi does and not have the hormones to grow an awesome playoff beard. Girardi is the bona-fide playoff beard sleeper. Looking at Danny, you may not think he has the potential to make something work with his beard, but I remember glimpses of an awesome beard back when the Rangers played the Penguins in the second round of the playoffs a few years back, and he can grow one. It will be nice to see a fine patch grow among that chiseled chin of his, too.
Ryan Callahan
A fine captain needs a fine playoff beard. And since we will have Captain Cally at the helm this years playoffs, he must grace us with a beard. Callahan is as rough and tumble as they come, and if is actions were a facial hair, they'd be a Chuck Norris beard. And if you have a problem picturing his beard, imagine how it will look when he skates up to Gary Bettman after hearing the words "Captain Ryan Callahan, come get the Stanley Cup!" *chills*
