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.

Since then, quality starts have become widely adopted, and I've lost track of everywhere that they have been featured. They're even used by several front offices, and it's available at Hockey Reference.

The attachment includes all the Quality Start data you'd ever need for the 2007-08 through 2017-18 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 11 seasons.
