An idea blatantly lifted from baseball, Quality Starts were one of Hockey Prospectus' first contributions back in 2009 as a measure of whether a goaltender "gave his team a chance to win". In order to record a Quality Start, the starting goalie must stop at least a league average number of shots (typically 91.3% prior to 2009-10, and 91.7% since), or play at least as well as a replacement-level goalie (88.5%) while allowing two goals or fewer.
Quality Starts are posted and analyzed on Hockey Prospectus on a regular basis. (Quality Starts 2009-10, Quality Starts 2010-11 and mid-season). It was also featured in the Hockey Prospectus 2011-12 and 2012-13 books, where Quality Start data was included for every goalie over the past three seasons.
Not only has it been adopted by several NHL front offices and its honourary spokeperson Cam Charron, who uses it regularly for everything from his look back at the 2007 Vezina race for Nucks Misconduct and The Province, his analysis of Ondrej Pavelec over at jets Nation or his look at the Washington Capitals for the Score, but by other hockey analysts everywhere, like Keith Quinn's look at the New York Islanders for Lighthouse Hockey, Glen Miller's take on Steve Mason for the Hockey Roundtable or Steve Burtsch of Pension Plan Puppets analysis of the Toronto Maple Leafs.
The attachment includes all the Quality Start data you'd ever need for the 2007-08, 2008-09, 2009-10, 2010-11, 2011-12 and 2012-13 seasons, including game-by-game breakdowns, season-by-season summaries for every NHL goalie, as well as multi-year totals for any goalie who has started even a single NHL contest in the past six seasons.
