I just think you're focusing on the negative aspects of his game too much. I think the guy has proven himself pretty convincingly over the past 2 years.
How can you ignore it?
Before I go on, I'm a Pens fan just like you are. I was born in Altoona, PA, grew up with the Pens.
This has been an issue with Murray since day one in the NHL. Either he can't fix it or maybe he is just focusing on the positive things he does and concedes that going glove side high will always work on him.
As to his success, yes there is no arguing that.
However, this is the first season he is playing where he is the #1 goalie with no legitimate backup behind him, and he got paid.
We're going to find out just how good he is without one of the best goalies in franchise history pushing him and with his wallet fat.

(First though, he needs to be taught what backchecking is...it's always been a foreign concept to the guy)
