Agreed on the Coyotes.
So you are saying that Scrivens's decrease is entirely random?
How about Dubnyk? He was .916 on the Coyotes. He's .939 on the Wild. Same season. How about Fasth in his first season on the Ducks and this one? This is not to say that save percentage is often not a good indicator of strength of goalie, but that sometimes it isn't, and the quality of the team can affect save percentage....to a degree, of course.
To me Mike Smith's .903 this year, is a lot more commendable than Kari Lehtonen's .907.
I don't know why Ben Scrivens has such a poor save percentage this year. The quality of a team has not been shown to have a significant effect on goalie save percentage. Viktor Fasth had all of 30 games in the NHL - it's not hard for a mediocre goalie to put together a good 30 game stretch. Devan Dubnyk had 140 games of being a perfectly average goalie save percentage wise until his collapse last year, and Edmonton sucked all of those years, so why did it happen then?
There's a ton of chance involved with whether or not a shot goes in. Schneider is showing this year that a garbage team can have a goalie with a great save percentage, and Sabres teams of the past showed this about Dominik Hasek.
