He's resume speak for himself. For some reason Jonathan Quick gets all the love, but Crawford gets none. Crawford have since 2012-13 sv% .926, .917, .924, .924, .918 and so far in this season .930. That's pretty darn good and easily top 5 material.
Rask, Lundqvist and Rinne are the most overrated ones. They were good years ago, but now they're average at best. Some could argue that Lundqvist is bottom tier goalie right now.
Healthy Bob seems to be easily the best one. Too bad he's from Russia and plays in Columbus. Put him in Canadian market and he's NHL's top 3 superstar. By media attention right now he's ranked somewhere 50-60.
