Welcome to Hockey Prospectus!
Here are our current and former writers and contributors, many of which have gone on to work for NHL teams or mainstream media.
Attorney Doug Abrams was a guest writer who penned his brief As Easy as CBA: “Be Careful What You Wish For” article for Hockey Prospectus in December 2012. Since July 2014, Abrams has written for The Hockey Chat. Twitter: @dabrams2021
Hockey Prospectus’ flagship statistic Goals Versus Threshold (GVT, explained in parts 1, 2, and 3) was introduced by founding writer and resident statistician Tom Awad. He also innovated the VUKOTA projection system and Delta SOT, the first adjusted version of Corsi.
Tom provided most of the stats for all five books, including the tables in the back – he even contributed the Los Angeles team essay in 2011-12. His Numbers on Ice column ran regularly from 2009-10, and occasionally until 2012, and his Player Power Rankings continue to run to this day. His most memorable contributions include his What Makes Good Players Good series (parts 1, 2, 3, and 4), and his contributions to the shot quality debate.
Tom is one of three founding Hockey Prospectus writers to remain active to this day, recently co-authored the 2014 edition of Rob Vollman’s Hockey Abstract, and currently works as an electrical engineer in Montreal, where he lives with his wife Marisa, and children David and Karina.
Stephen Burtch wrote a guest piece in November 2014, comparing score-adjusted metrics to score-close metrics in their predictive power. He previously wrote for David Johnson’s Hockey Analysis website, and has written for Pension Plan Puppets since 2010, and Sportsnet as of the 2014-15 season. One of the earliest believers in Delta, Stephen subsequently innovated a popular variant of his own called dCorsi during the 2014 offseason. Stephen is a math and physics teacher in Toronto.

Hockey Prospectus was officially launched in 2009, originally under the Puck Prospectus name by its founding Executive Editor, Will Carroll. The well-known injury expert’s Under the Blade column ran throughout 2009, and he also contributed an essay on upper body injuries for our first book, Hockey Prospectus 2010-11.
While this may have been his lone foray into the world of hockey, Will is very well known in the world of baseball and football, where he has authored three books, won several FSWA awards, has worked for a MLB team; he is a member of the Baseball Writers Association of America and the Pro Football Writers Assoication He is currently at Bleacher Report, where he’s the lead writer for sports injuries, and has hosted several audio programs. Twitter: @injuryexpert
Matthew Coller has been Managing Editor of Hockey Prospectus since 2013 and is the long-time host of the popular Hockey Prospectus Radio podcast, as well as producer and host at WGR SportsRadio 550 in Buffalo. He has been a regular columnist since 2012, but without one of those catchy names.
Matthew was involved in all but the first Hockey Prospectus book, writing the team essays and/or player profiles for Boston and Buffalo, as well as one-time contributions on four other teams. Twitter: @MatthewWG
Thomas Crawshaw is a UK-born/bred/based hockey obsessive, and the foremost hockey analytics expert in the field of injuries. He is the inventor of the CHiP statistic (Cap Hit of Injured Players, explained in parts 1 and 2), and was the featured injury columnist throughout January 2014. Thomas continues to write on his Springing Malik blog, which he launched in 2008. Twitter: @lw3h.
Already a prominent name in the field of hockey analytics thanks to his work with the Wall Street Journal, National Post, Globe and Mail, and for teams and agents in four major sports, Gabriel Desjardins was one of the founding writers of Hockey Prospectus.
His column, appropriately named Behind the Net after his own famous website, ran regularly throughout 2009 and some of 2010, and featured cutting edge analysis on a variety of topics, including the value of fighting, how dangerous rebounds are, or defensive zone faceoffs, when to pull the goalie, quality of competition in the junior leagues, shootouts, and shot quality. He even penned the first French-language article on Hockey Prospectus, Derriere Le Filet. He contributed an essay on the statistical revolution to Hockey Prospectus 2011-12, and the Foreword to Hockey Prospectus 2012-13.
Gabe re-branded his website as Arctic Ice Hockey when hockey returned to Winnipeg for the 2011-12 season, where he continued to write for most of that inaugural season. He currently works in Silicon Valley. Twitter: @behindthenet
We need an asterisk here—David Driscoll-Carignan was one of the founding writers involved in its launch, but never actually published a piece with Hockey Prospectus. David, who launched his own blog In the Cheap Seats in 2007, moved on to Mile High Hockey instead, and then to NHL-blogs from 2011 until the 2013 offseason.
John Fischer founded, writes for, and is one of the managing editors of In Lou We Trust, a New Jersey Devils blog. He is also a regular guest on Talking Red, a New Jersey Devils podcast.
John’s contributions to Hockey Prospectus primarily include its two most recent books, Hockey Prospectus 2013-14 and Hockey Prospectus 2014-15, where he penned team essays and/or player profiles for New Jersey and the New York Rangers, among others.
John spends most of his day as a quality engineer, but he can be seen—and usually heard—at New York Red Bulls soccer games, and football games of his alma mater, Rutgers. Twitter: @JKFischer
One of the earliest names in the field of hockey analytics, Marc Foster was actually involved in the first attempt at a Hockey Prospectus book way back in 2001. At the time, he was one of the community’s lone voices, running the Hockey Research Association, which he founded in 1999, and writing for SI.com.
Marc finally made his debut with Hockey Prospectus with his Benchmarcs column, which ran regularly throughout the 2010-11 season. In it, Marc looked at a variety of topics like the effect of goalie workloads, predicting the standings with the pythagorean formula, and the value of unrealized draft picks, some of which were built around concepts he pioneered a decade earlier. Twitter: @mfosterftw
Founding writer Iain Fyffe’s Up and Coming column ran regularly from 2009 to 2011, and the Pucks from the Past columns from 2011 to 2013. The former was a careful study of player projection and the NHL entry draft, while the latter was a long-running series on the hypothetical results of the fictional Saskatoon Westerns club using his Projectinator system from 1983-84 through the year 2000. He also introduced his Hall of Fame Inductinator system during his tenure with Hockey Prospectus.
Hockey Prospectus’ resident historian, and one of the longest-serving names in hockey analytics, Iain contributed an essay on the history of statistical analysis in hockey in Hockey Prospectus 2010-11, and of hockey in Winnipeg in Hockey Prospectus 2011-12. He also wrote the team essays for Montreal and Toronto in both volumes, and for the entire Atlantic division in the former.
Iain is a charter accountant living in Fredericton, New Brunswick with his wife and two kids. In 2014, he authored On His Own Side of the Puck, co-authored the 2014 edition of Rob Vollman’s Hockey Abstract, with A Nor’west Blizzard still under development. His work can be found on his Hockey Historysis blog, which also includes re-runs from his 2001 pioneering website, Puckerings. Twitter: @IainFyffe
Co-editor of the Hockey Prospectus 2014-15 annual, Adam Gretz has been a freelance writer based out of Pittsburgh since 2008. He has covered two Stanley Cup Finals, two NHL Winter Classics, and an NHL Entry Draft.
Adam was an occasional columnist for Hockey Prospectus early in the 2013-14 season, and wrote the team essays and/or player profiles for Arizona, Nashville, and several other teams in Hockey Prospectus 2013-14 and Hockey Prospectus 2014-15. Adam has been a frequent and popular guest on Hockey Prospectus Radio, where he and Matt vie for the hottest takes in hockey.
Starting in the 2014-15 season, Adam has returned for a second stint at CBS Eye on Sports, and his work has also appeared at SB Nation, About.com, Today’s Slapshot, AOL, and Deadspin. Twitter: @AGretz
One of the exciting new names in the field is Sam Hitchcock, whose By the Numbers and Between the Bluelines columns were featured on Hockey Prospectus throughout 2014. In them, Sam uses hockey analytics and close viewings to study acquisitions, line combinations, playoffs matchups, awards voting, and a variety of other items in the news.
Sam’s work also appeared in Hockey Prospectus 2014-15, where he wrote the team essays for Anaheim, Chicago, Los Angeles, Minnesota, and San Jose. His work can also be found on Intelligent Hockey, a website he founded in September 2013. Twitter: @IntelligHockey
Founding writer David Laurila’s regular Prospectus Q&A column ran from February through May of 2009, and gave readers an opportunity to hear directly from hockey players like Patrick Marleau, Nick Foligno, and Jenny Brine. While his foray into hockey was all-too-brief, he remained with Baseball Prospectus until 2013, and his coverage of that sport can still be found in many places, such as the New England Baseball Journal. Twitter: @DavidLaurilaQA
Jeff Levine, a lawyer for the Phoenix Coyotes in 2008, is currently a Sports Law lecturer at the University of Louisville. To us, he is known for his frequent and insightful guest appearances on Hockey Prospectus Radio throughout the 2013-14 season. Twitter: @jflevine
Brian Macdonald is Director of Hockey Analytics for the Florida Panthers, a position he assumed for the 2014-15 season. Here, he is best known for his work on Hockey Prospectus 2013-14, where he wrote the team essays for Winnipeg, Ottawa, and Buffalo, and for a series on NHL realignment that ran in February and March of 2013 (parts 1, 2, 3, and 4).
Formerly an assistant professor in the Department of Mathematical Sciences at West Point, Brian’s website Greater Than Plus Minus still features his ground-breaking work in adjusted plus/minus, goaltending analytics, his playmaking metric (PLAY), and his work on realignment. Twitter: @GreaterThanPM
Micah Blake McCurdy burst onto the scene in November 2014 with a new version of Eric Tulsky’s Score-Adjusted Fenwick. He made his Hockey Prospectus debut later that month with an attempt to project the divisional standings (and updated). Micah’s work can also be found on Sen Stats and his own Hockey Charts website. Twitter: @IneffectiveMath
There is no more established name in the field of goaltending analytics than the Contrarian Goaltender, Philip Myrland. His In the Crease column ran regularly from last 2009 through 2012, and took detailed looks at specific goalies, and into specific questions, like goal support and shorthanded save percentage.
Our resident goaltending expert was involved in the first four Hockey Prospectus books, writing a total of nine team essays, including three for Phoenix and two for San Jose. He still writes very occasionally on his Contrarian Goaltender blog. Twitter: @tcghockey
Michael Nowak briefly appeared as Hockey Prospectus’ fantasy hockey columnist from February to March 2014. Born and raised in Buffalo, Michael is currently covering fantasy football for Dobber Sports. Twitter: @NowakHockey
One of the newest additions to Hockey Prospectus is Arik Parnass, whose column first appeared early in 2014-15. Arik is a Montreal native and a senior at Georgetown University, where he is majoring in government and minoring in journalism, while also completing coursework in statistics and programming.
Very well-known in the wider world of sports, John Perrotto made Hockey Prospectus his destination for one of his few forays into the world of hockey; John’s On the Beat column ran for about a year from September 2010 to 2011. Just as he was for our then-cousins at Baseball Prospectus and Basketball Prospectus, John was our man in the field, getting quotes from players, coaches, and owners.
While occasionally popping up in the world of hockey to cover the Penguins, John is easier to find covering baseball and basketball for USA Today. Twitter: @JPerrotto
Matt Pfeffer joined Hockey Prospectus (and the Hockey News) early in the 2013-14 season. Since then, he has applied his expertise with hockey analytics to topics ranging from the Hall of Fame, rink effects, score effects, adjusting Corsi for zone starts, to clutch play. Matt was responsible for the many visualizations and statistics hosted on the website, and for introducing adjusted on-ice statistics (AdjCF% and AdjGF%) to Hockey Prospectus 2014-15.
Matt is the Director of Analytics for the OHL’s Ottawa 67’s and has consulted for PowerScout and several professional hockey teams. He is also founded Progressive Hockey, one of the leading on-line statistical databases. Twitter: @MattyPfeffer
Richard Pollock is best known at Hockey Prospectus for his weekly column, which was appropriately named Illegal Curve after his own website and show on Sports Radio 1290 in Winnipeg, where he can still be found today. His column ran from 2009-10 to early in the 2011-12 season, and focused primarily on finding the relationships various factors had on winning. Richard previously wrote the NHL Entry Draft column, which ran weekly throughout the last half of the 2008-09 season.
Richard wrote nine team essays for Hockey Prospectus 2010-11 and Hockey Prospectus 2011-12, including Tampa Bay, Washington, and Atlanta/Winnipeg both times. He also wrote an essay calling for a balanced schedule in Hockey Prospectus 2010-11. Twitter: @illegalcurve
Ryan Popilchak’s Front Office Focus was a popular regular feature throughout the 2010-11 season, and also ran sporadically throughout 2011-12. In it, he would take a close look at the value of contracts, and was best known for introducing the Heavy Lifter Index in December 2010.
Ryan wrote the team essay for Ottawa in Hockey Prospectus 2011-12, wherein he also revisited the Corsi statistic, and the essay for Carolina the following season. Born in Sylvan Lake, Ryan currently lives in Calgary with his wife Rita. Twitter: @sprtopinionated
One of our most prolific writers, Corey Pronman is the final word on prospect analysis, blending traditional scouting with hockey analytics. He has published over 300 articles since his debut in October 2009.
Corey’s Daigle to Datsyuk column, which launched in the 2009-10 season, is one of the longest-running and most popular features at Hockey Prospectus, especially when including his associated Top 10 Prospects series. Notable highlights include his look at goaltending parity in the draft (parts 1 and 2), and his series on changing the development systems (parts 1, 2, and 3). Interestingly, Corey initially penned columns named Moneypuck and Hockey Today before settling on prospect analysis, and branched out into the deadline-focused Buyers and Sellers column in 2011.
Corey is certainly best known for his Top 100 Prospect Rankings that appeared in our first four books, including Hockey Prospectus 2012-13, where he also wrote the team essay for Montreal, his original hometown.
A former junior hockey scout in the USHL, and current member of the PHWA, Corey’s work has been featured on websites and podcasts throughout the league, and is now available exclusively through ESPN Insider. Twitter: @coreypronman
Not only was Andrew Rothstein the founding Managing Editor of Hockey Prospectus, but until November 2010, his Ice Actions (and later Dropping the Puck) column was the go-to destination for fans looking to keep up with current events around the league from an analytics perspective.
Andrew was also the co-editor of Hockey Prospectus 2010-11, wherein he wrote team essays for Chicago, Columbus, Detroit, Nashville, and St. Louis. Andrew’s post-HP life included launching the short-lived Sabermetrics Network YouTube channel in the summer of 2012, before moving on to other pursuits near his Long Island hometown.
Ryan Schwepfinger served as the fantasy hockey columnist for all of 2013, authoring the weekly Shots on Goal column originally launched by Timo Seppa in the early days. Ryan also served as Managing Editor for the website that year, and was co-editor of both Hockey Prospectus 2013-14 and 2014-15, the former in which he contributed the player profiles for the Columbus Blue Jackets.
An alumnus of The Ohio State University, he previously held communications positions for the MLS’ Philadelphia Union, the New York Rangers, and the Philadelphia Flyers and was the Media Relations Coordinator and Broadcaster for the USHL’s Youngstown Phantoms, while seeking his Master’s degree in Sports Business at Temple University in Philadelphia. Ryan is currentl Communications Manager at Columbus Crew SC. Twitter: @ryanschwep
Founding writer Timo Seppa served as Managing Editor from 2010 through 2013, and as owner and Editor-in-Chief since then. He also written over 200 articles, served as an editor on all five Hockey Prospectus books, introduced countless innovations, appeared regularly on NHL Network Radio’s The War Room, has covered multiple drafts, combines, and Stanley Cup Finals, and has consulted for two NHL teams over the past three seasons. Yet, his claim to fame is probably his uncanny ability to pick both the Stanley Cup champion and the number of games for five years running.
Simply put, Timo Seppa is Hockey Prospectus. Serving as editor on all five Hockey Prospectus books, including by himself in 2011-12 and 2012-13, Timo was also one of the lead writers for the first three seasons, writing all the team essays for the old Atlantic division, and introducing metrics such as the Ultimate Faceoff Percentage (UFO%) and Core Age in 2011-12, and New Power Play Percentage in 2012-13.
His many long-running columns Mucking and Grinding, Shots on Goal, Driving to the Net, Prospectus Q&A, and Player Power Rankings have given us countless insightful moments, including his look at the Matrix, the Hot Goalie Index (or Goalie Heat Index), Ultimate Faceoff Percentage (UFO%), and his can’t-miss 2011 series on Patrice Bergeron and the Bruins power play (parts 1, 2, 3, and 4), originally published in the Maple Street Press’ Bruins Annual 2011-12.
Timo resides in Connecticut with his wife and three daughters, and can be tracked down at just about every Quinnipiac Bobcats hockey game. Twitter: @timoseppa
Building on the playmaking metrics earlier devised at Hockey Prospectus, Ryan Stimson kicked off a ground-breaking project to manually counting passes for the New Jersey Devils in the 2013-14 season. Ryan summarized the early results of his analysis in 2014 (parts 1 and 2), and has recruited three more statisticians for his pass-tracking project in 2014-15. Regular updates on both Ryan’s pass-tracking project, and his contributions to Pierce Cunneen’s Zone Exits project, have been available at In Lou We Trust since October 2013. Twitter: @RK_Stimp
Currently consulting for an unspecified NHL team, Corey Sznajder wrote for Hockey Prospectus throughout 2013, also contributing the team essays and player profiles for Carolina, Tampa Bay, and Washington for Hockey Prospectus 2013-14. He made a guest appearance to again cover the Carolina Hurricanes in the most recent annual.
Before his recent hiring forced him to “go dark”, Corey was working on his ground-breaking All Three Zones project to track zone exits and entries for all NHL teams in the 2013-14 season. His analysis had been available on his Shutdown Line blog since July 2011. Twitter: @ShutdownLine
One of the founding writers with a single piece in February 2009, Leslie Treff finally made her return as a regular columnist in September 2013 with On the Horizon, and with her Top 100 NHL Prospects in Hockey Prospectus 2014-15, taking over for Corey Pronman in the latter effort.
Leslie has been covering prospects for Hockey’s Future since 2005, primarily focusing on the New York Rangers, the CHL, and college hockey. A former scholastic and collegiate athlete, Leslie has training in law, statistics, and journalism. She is a member of the PHWA. Twitter: @HFNYRangers
One of the field’s most established names, Eric Tulsky’s contribution to Hockey Prospectus 2012-13 was entitled Measuring Zone Entries. That adds Hockey Prospectus to a long list of Eric’s publications that includes Broad Street Hockey, NHL Numbers, Five Thirty Eight, and his own blog, Outnumbered. Unfortunately, Eric’s hiring by an unspecified NHL team for the 2014-15 season has forced one of our community’s most gifted innovators to “go dark”. Twitter: @BSH_EricT
Founding writer Rob Vollman has written over 200 articles since his Howe and Why column first appeared in February 2009. Since then, he has been responsible for almost countless innovations, including Player Usage Charts, Quality Starts, Goals Versus Salary (GVS), Setup Passes, and advances in League Equivalencies (NHLe), and Historical Player Projections, to name just a few.
Rob was one of three authors involved in all five books, writing a total of 39 team essays, and almost as many sets of player profiles. He covered Columbus four times, and St. Louis, Nashville, Minnesota, Detroit, Anaheim, and Colorado three times apiece. Rob also contributed essays on Corsi and League Equivalencies (NHLe) in the 2010-11 edition, and on Quality Starts the following season. He introduced Player Usage Charts with the 2012-13 edition, and Total Performance Charts in Hockey Prospectus 2013-14.
Rob has since written two books of his own in the Rob Vollman’s Hockey Abstract series, and co-authored the 2014-15 edition of McKeen’s magazine. He appears as a radio guest in most NHL cities, is a member of the PHWA, and has a weekly armchair GM feature on ESPN Insider. Twitter: @robvollmanNHL
Working the transaction beat for Hockey Prospectus since September 2011 is Ryan Wagman, with his regular Zamboni Tracks column. He is also the creator of the beloved Hootenanny Award, given each year to the most successful player to start the season outside of the NHL. Ryan’s debut was actually in the 2009 offseason, when he wrote the short-lived Around the League series.
Ryan has written 11 team essays for Hockey Prospectus 2012-13 through 2014-15, including Dallas and his hometown Toronto for all three seasons. He is a veteran of two years in the Israeli army, manages a team of technical writers for a tax consulting form, and lives just outside Toronto with his wife Maya and daughter Georgia. Twitter: @RAWagman
Joe Walsh was one of the founding writers, originally intended to pen the weekly column The Rumor Mill, which unfortunately never came to pass.
Jonathan Willis’ popular Angles and Caroms column ran from February 2011 through May 2013. It explored a variety of topics, most notably his mid-term evaluations of prospects in 2011 (parts 1, 2, 3, 4, 5, and 6), and his thorough, textbook analysis of the 2011-12 Columbus Blue Jackets (parts 1, 2, 3, and 4).
In print, Jonathan contributed a dozen team essays to Hockey Prospectus 2011-12 through 2013-14, and even more sets of player profiles.
Since 2008, the ubiquitous analysis of Jonathan can also be found at the Edmonton Journal, Copper and Blue, which he founded, the Nations Network, where he also worked as a managing editor, Grantland, ESPN Insider, The Score, Bleacher Report, and Yahoo’s Puck Daddy. By day, he is based in British Columbia, working as an account manager for an energy service firm. Twitter: @jonathanwillis
Kent Wilson’s beloved brand of analysis was featured in his Stats and Fury column, which ran throughout the 2010-11 and 2011-12 NHL seasons. Typical examples include his look at the numbers behind the firing of Davis Payne, his comparison of David Steckel and Brian Betts, his analysis of Philadelphia GM Paul Holmgren’s 2011 offseason, and his bang-on analysis of Bobby Ryan. Kent also kept readers up to date on the analytics developments from around the league when he penned the Dropping the Puck late in the 2010-11 season.
In Hockey Prospectus 2011-12, Kent re-visited Corsi, and wrote the team essays for the Northwest Division, and he recently returned to write the team essays for Calgary and Edmonton in Hockey Prospectus 2014-15.
Since early 2009, Kent is best known for being a writer, editor, and former overlord on the Nations Network, including NHL Numbers and Flames Nation, but has also been a regular contributor to Five Hole Fanatics, Matchsticks and Gasoline, The Score, Yahoo’s Puck Daddy, and his hometown Calgary Herald. Twitter: @Kent_Wilson
One of our newest arrivals is Rochester, New York’s Ryan Wilson, who made his debut in April 2014. Lately, he has picked up the goaltending mantle, using Quality Starts to evaluate Marc-Andre Fleury, and looking at correlations with postseason play. In print, Ryan wrote the team essay for Pittsburgh and the player profiles for Colorado and Ottawa in Hockey Prospectus 2014-15.
Ryan’s work can also be found at Hockey Buzz, where he first made his name when he started covering the Pittsburgh Penguins back in mid-2013. Ryan carries a Master’s Degree in physical education/health and is NYS teacher certified, with over a decade’s worth of experience coaching hockey at the varsity high school level. Twitter: @GunnerStaal
A Philadelphian by birthright, Erik Yost has written the Flyers team essay in both Hockey Prospectus 2013-14 and Hockey Prospectus 2014-15, and is our go-to resource for any matter related to the team. His first formal appearance on the website was on Hockey Prospectus Radio in November 2013, and he has popped by to contribute the occasional Flyers-themed analysis ever since.
Erik is a 2011 graduate of The Ohio State University with degrees in Journalism and Psychology, and spends his day working at a special-needs school and coaching Special Olympics. Erik currently resides in southern New Jersey. Twitter: @ErikYost_
