I don't know what the full story is. And, I'm not sure any type of explanation will suffice. I will never comprehend the reasoning behind this. To put it in other terms, it's like replacing Harry Caray with Bob Uecker. Mike Lange is the voice of the Pittsburgh Penguins. Paul pales in comparison. I know they are both exceptionally knowledgeable in the world of hockey, but Lange actually has the personality for television. Paul barely sparkles on the radio.
Also, congratulations on the Hockey Hall of Fame for finally recognizing that Herb Brooks belongs there.
