From the moment he came to Pittsburgh, Murray has looked like a well-coached goalie. He may have been the most technically sound rookie I've ever seen (he's at least the most technically sound rookie I remember) and he is already close to being the most technically sound goalie I've ever seen play for the Pens. Vokoun was better, but Vokoun was 40, so he had to be. I can't imagine a guy playing like Matt Murray if he was developed under a lousy coach. It doesn't make sense. So I have confidence in Buckley.
On the other hand, I can't really point to any period in his career in which Fleury looked like a well-coached goalie. I can point to times when he produced, but not any prolonged periods of looking like a technical goalie with a competent coach. Now, it's clearly not fair to put the brunt of that on Bales. It's not his fault that breaking ten years of terrible habits is a hard thing to do. I'm just not seeing anything to outweigh what Buckley did with Murray.
