NHL 2013-14 Player Data

posted Apr 21, 2014, 3:20 PM by Robert Vollman

Around 350 stats on all 886 players who were in even a single game in the 2013-14season.

An annual tradition for a decade, this spreadsheet contains a complete collection of statistics, both basic and advanced, from a wide variety of analysts and web sites including Hockey Reference, Gabriel Desjardins' Behind the Net, Darryl Metcalf and Extar Skater, Tom Awad and Hockey Prospectus, Cap Geek, NHL's official feed, and much more.
 
As always it includes biographical information, the basics, useful metrics (like zone starts, penalties drawn and percentages), advanced Corsi-based statistics, and established stats like GVT and Point Shares - all broken down by situation.

This year the work has been divided into separate sheets for each manpower situation.

Check back often as additional information is always added as they become available.

NHL Translations

posted Apr 11, 2013, 10:47 AM by Robert Vollman

When Hockey Prospectus first launched in 2009 (as Puck Prospectus) the very first article was about translating scoring totals from the Russian league to the NHL, and was quickly followed up with a piece that looked at the Swedish Elite League (elitserien). Each piece used a system pioneered by Gabriel Desjardins in 2004, borrowed from baseball’s Bill James, to calculate the average change in scoring totals for all the players who came to the NHL after playing in other leagues.
 
This type of work depends on having a set of data that includes the raw data for everyone who played in another league, like the European, US College or Canadian junior leagues, the year before playing in the NHL.  Using the attached spreadsheet allows everyone to conduct their own analysis with NHL translations.

NHL Coaching Data

posted Feb 1, 2013, 2:59 PM by Robert Vollman

A good coach will make a bad team competitive, and a good team great.  While it is difficult to rate coaches, a good start is to measure how well their team did relative to how well they did the previous season, once regressed to the norm by 35%.  With sufficient data we can start to see which of history's coaches might have been the most effective.
 
It probably comes as no surprise to see Scotty Bowman far, far atop the list, with Ken Hitchcock right behind as the league's most accomplished active coach.  It's also interesting to see how much better non-NHLers did as coaches relative to those who had played in the NHL, or how among those who played in the NHL it doesn't seem to make a difference if they made the Hall of Fame, but does seem to matter what position they played (defensemen make better coaches).
 
Download the attached data and make your own calculations, perhaps restricting the study only to the post-expansion era, or changing the degree of regression (possibly by era). 
 

Setup Passes, 2007-14

posted Dec 30, 2012, 11:17 AM by Robert Vollman   [ updated Apr 21, 2014, 4:49 PM ]

Setup passes were introduced at the end of 2012 (as simply "Passes"), and explained in more detail in both Hockey Prospectus 2013-14 and Hockey Abstract.

Setup passes are defined as those passes which result in shots on goal, and can help determine which players are most adept at setting up shots in a way that's independent of shooting percentages. 

Unfortunately this statistic is not recorded by the NHL (or anyone else). It is therefore available only as an estimate based on the player's (primary) assists and the average shooting percentage of his linemates. To some people that's a tremendous turn-off, even among those who think the concept is excellent. If you are of that mind, think of it only as a handy re-presentation of primary assists and on-ice shooting percentage.
 
The attached spreadsheet has the raw data and the formula, which has been refined since its initial introduction. There are further refinements in the works, including one based on all attempted shots (Corsi) and one that correctly removes the players own shots from the on-ice shooting percentage.
 

2004-05 Lockout

posted Sep 28, 2012, 1:27 PM by Robert Vollman

NHL players went to a variety of different leagues during the 2004-05 lockout.  For every NHL player that played somewhere during the lockout, and immediately came back to the NHL - even if just for a single game in either case, attached is a spreadsheet of their basic statistics (GP, G, A, PTS) for each of those seasons. 
 
If the NHL is once again unfortunately locked out in 2012-13, ideally the attached information can be used to help predict how well these players will score in those other leagues, and how they might fare upon their return.
