that would be a great goaltending stat, if he had control over how many shots he faced. GAA is nothing more then the result of shots against and save percentage. it does not provide an accurate picture for how the goaltender played. in save percentage, everything is equal. simply put, its the ratio of goals to shots against. if one goalie is facing 34 shots a game, and another is facing 25, who is going to have the lower GAA? its not cherrypicking, its the truth. the most accurate statistic when evaluating a goaltender is save percentage, while one of the most misleading is GAA. and this isnt some random theory i concocted, im merely parroting what many NHL analysts have been saying for years, though once i heard it, i immediately realized its truth. i mean, GAA is what the veznia used to be based off, before they decided to change that to best overall play (the number 1 stat they look at? save percentage. its how luongo almost won a veznia on a non playoff panthers team) and then look at the jennings trophy. lowest GAA. look at who wins it. typically, teams with stacked defenses. brodeurs won the thing 5 times! even osgood has one.
i mean, shit. how many times have you seen someone score on miller, and thought, gee, the defense hung miller out to dry on that. not his fault. do you look at the box score the next day, see 4 goals against, and say "a GAA of 4?! get this guy outta here!" course not. so why are we doing that to everyone else?
GAA is more indicative to the team in front of the goaltender rather then himself. certainly, exceptions exist, and more often then not, GAA and save percentage go hand in hand. but, seeing this started with the mentioning of rask, when you see him have an inflated GAA, but a high save percentage, you have to realize the weight of one shows more of how he is playing.
http://en.wikipedia.org/wiki/Goals_against_average"Since the statistic is highly dependent on the team playing in front of a goalie, save percentage is usually considered a more accurate measure of a goaltender's skill, especially in ice hockey and lacrosse."
