Historical Data on Best-of-7 Series Added to Hockey Reference

Posted by Mike Lynch on May 28, 2015

We're excited to introduce a new resource for our users to enjoy during the Stanley Cup Playoffs. This new feature contains a game-by-game breakdown of how teams in any given situation fare in Best-of-7 series.

The page consists of a series of tables. The first one shows the home team's record in any given game of a series:

Regular games & overtime games are self explanatory. Closeout games cover any game in which a team has a chance to clinch the series. Elimination games are games in which a team is facing elimination. All Game 7s are both closeout games & elimination games, so we have zeroed out those rows.

The second table is a little more complicated, but features some really cool information once you get acquainted with how to read it. Using this table, you can see how a team's historical odds of winning a given series change with each passing game. For instance, road teams that win Game 6 to tie a series at 3-3, have gone 34-23 in Game 7. Teams that take a 2-0 series lead go on to win the series 87.0% of the time, etc. This table contains the history of every position a team could be in in a Best-of-7 series.

Beneath that behemoth of a table is a simple table with every franchise's record in Best-of-7 series. It's sortable, so you can see that the Canadiens have won the most series and that the Oilers have the best series win percentage.

Finally, the fourth table features every franchise's record in the all-important seventh game. The data is broken down into overall record, home record and away record. Of particular note, with a home Game 7 looming for the Rangers, is that their 7-0 record is home Game 7s is the best in NHL history. You'll also notice that the accompanying winning percentages contain hyperlinks. If you click on those links, they will bring you Play Index query results listing each of those games. So you can easily see all 7 of those Rangers home Game 7s, and then click through to the box scores, as well.

We also wanted to give quick mention to a few other recent additions, in case you missed them:

All-time comebacks from down 3-0 or 3-1

Every Overtime Goal in NHL Stanley Cup Playoffs history

We hope you all can enjoy this new feature as much as we already are at the office. And enjoy what's left of the 2015 Stanley Cup Playoffs.

Stanley Cup Playoffs Comebacks Added

Posted by Mike Lynch on May 20, 2015

We just wanted to quickly point out that we have added a new Frivolity to the site: Teams to win a Best-of-7 series after trailing 3-0 or 3-1. The Rangers recent comeback against the Capitals got us thinking about this, so we figured we'd add the list. Please stay tuned for more cool Best-of-7 series features like this in the feature.

Every OT Goal in Stanley Cup Playoffs History

Posted by Mike Lynch on April 20, 2015

We just wanted to briefly mention that we have recently added every overtime goal in the history of the Stanley Cup Playoffs to our Frivolities section here. This section currently contains two tables. The first shows the goal scorer, date, team, opponent, OT sessions, final score and how much time had elapsed in the OT periods at the time of the goal. The columns in the table are all sortable in case you'd like to quickly look at OT goals scored for or against your favorite team or find the shortest/longest OT games.

The table on the right, meanwhile, lists the all-time individual leaders in playoff OT goals.

It should be mentioned that this is a comprehensive list of OT goals in Stanley Cup Playoff games between two NHL teams. It does not, however, include games featuring the NHL against the WCHL or PCHA. You may also notice a couple instances where the "winning" OT goal merely tied the game. This is because some early playoff series were determined by total goals, so a game a team held a lead in could go to OT in order to determine the series winner.

2015 Stanley Cup Playoffs Section

Posted by Mike Lynch on April 15, 2015

With playoffs season upon, we wanted to point out our 2015 NHL Stanley Cup Playoffs section. While it's mostly a shell right now, it will be a good bookmark for info as the playoffs get going. You can find schedule & results for every game, stats for every skater, goalie & team, as well as leaderboards.

There are also series preview pages to see how opponents match up with each other.

If you're more of a history buff, you can also take a skate down memory lane by checking out past playoff seasons, such as 2014 or 2013. Stats for series are also available, such as the 2013 Stanley Cup Final. Links to all playoff seasons (and a list of champions, runners-up and Conn Smythe winners) are available here.

Other Stanley Cup Playoff resources include our all-time Leaders & Records section, list of frequent champions and our Player Playoff Finder tool. With the Player Playoff Finder, you can run all sorts of custom queries such as leading goal scorers, assists leaders, short-handed goal leaders and many others.

Our Team Game Finder & Player Game Finder also contain options to restrict your searches to playoff games only. You can search for things such as the most recent playoff hat tricks & team records in their playoff openers. It should be noted that our player game logs currently go back to the 1988 Playoffs.

We hope you enjoy these features and please let us know what you'd like to see in the future.

Box Plus Minus/VORP for the Playoffs

Posted by David Corby on February 9, 2015

 

Playoff Box Plus/Minus (BPM)

We're now able to calculate Box Plus/Minus (BPM) and Value Over Replacement Player (VORP) for the playoffs, by extending the methodology used for the regular season, and calculating a team efficiency rating based on performance in the playoffs, adjusted for strength of playoff lineups (by using playoffs minute distributions and regular season BPM ratings). These ratings are interesting in themselves, and reflect some of the great playoffs runs - the 1996 Bulls' rating was +19.3, and the 2001 Lakers were +20.1.

The BPM figures themselves reflect the best individual playoff performances. LeBron's 2009 BPM of 18.2 is tops by a large margin, followed by Kareem's 1977 run and then the Jordan playoffs from 1989-1991.

(For a detailed explanation and further discussion see the "Playoff Box Plus/Minus and VORP" section of the write-up.)

 

Playoff VORP (and Pro-Rating the Regular Season)

As well as BPM, we can now calculate VORP for the playoff season. (If you need a refresher on VORP as a concept, please visit the original write-up when we introduced it to Basketball Reference). We calculate VORP for the playoffs similarly to the regular season - that is, [BPM - (-2.0)] * (% of minutes played) - and it should be interpreted identically. Again, that's as the number of points the player has produced over a replacement player, per 100 team possessions.  The significance of VORP compared to BPM is that it's accumulative, rather than a rate stat, and thus accounts more literally for value provided, weighted as it is by minutes played, and expressed on a per-82 game basis*.

(* - Yes, this is new. We are now pro-rating VORP based on the number of games that a team has played during the regular season, and doing the same for the playoffs. One point of VORP is one point of full season team efficiency differential. This affects partial seasons, strike-shortened seasons, and the playoffs.  This has significance for the playoffs, in particular - players on teams that go further or play in 7-game series will accumulate more because they have more opportunities.)

 

Some Minor Changes to the Equation

Please note that we've also updated the methodology, such that some players will have a slight variation in the BPM and associated stats. These were technical fixes to the regression methodology, which had the result of slightly changing the relative value of component stats. For example, blocks and shooting efficiency are two factors that are more highly favored by the revision and thus Anthony Davis saw the largest increase in BPM (+0.8), however most changes were of a much smaller magnitude. Please see the details of this revision in the write-up, under the "Updates" section.

 

Again, Basketball Reference extends its thanks to Daniel Myers, whose research the above represents. Also, please see the revised 'About BPM' write-up that details the methodology and is generally extremely useful for understanding the context of BPM and VORP, and the best ways to think about and use these stats.

Explore PFR’s Super Bowl Section

Posted by Mike Lynch on January 23, 2015

If you haven't seen the Super Bowl Section of our site yet, you should head over and check it out right now, because we think it's pretty awesome. Here are some of the features you'll find once you get there:

And best of all is the Super Bowl Play Finder tool. It's similar to the Play Index Game Play Finder tool, but limits your searches strictly to Super Bowls and allows you to search through every play of all 48 previous games. Some examples:

Our Player Game Finder and Team Game Finder are also unique tools for Super Bowl research. You can use them to find things like every 100-yard rusher in Super Bowl history, the largest point spreads in Super Bowl history or the highest over/unders. You can also identify trends such as the record of the team leading after one quarter (26-11), at halftime (36-10) and through three quarters of play (39-8).

So go ahead and try the Super Bowl Section right now -- it's free, easy to use, and best of all, with it you'll be able to dominate anyone who challenges you in Super Bowl trivia.

UPDATE: We have also added a Super Bowl filter to our Drive Finder, which allows users to find things such as the longest drives in any Super Bowl since 1998 or the fastest Super Bowl touchdown drives since 1998.

Corrections to 1994 Pacers Playoff Statistics

Posted by Mike Lynch on June 20, 2014

It recently came to our attention that there are some conflicting scores listed by various sources for Game 6 of the 1994 Pacers/Hawks Eastern Conference Semifinals series. This prompted some digging here. As a result, we have changed our score, from 97-79, to a 98-79 final. The extra point has been awarded to Antonio Davis for making 1 of 2 FTA in the 4th quarter.

However, this also led to our discovery that some of the "official" playoff totals for the 1993-94 Pacers are not correct. They are "officially" credited with 1,444 points in the 1994 Playoffs, but if you add up all of their scores, you will get 1,445. Similarly, Antonio Davis is "officially" credited with 134 points in the 1994 Playoffs, but if you add up his game logs, you will get 135.

It is our belief that the 98th point we were missing from our Game 6 score has gone unaccounted for in NBA stat totals for the last 20 years. As such, we are adjusting the Playoff scoring totals for the 1994 Pacers. The team will now be credited with 1,445 Playoff points (rather than 1,444) and Antonio Davis with 135 Playoff points (rather than 134). Additionally, 1 FTM and 2 FTA have been added to the Pacers' total (all credited to Davis).

Thanks to this correction, Davis has moved past Larry Foust for sole possession of 219th place on our NBA all-time Playoff scoring list. Congratulations, Antonio!

Added Advanced Stats to NBA Playoff Series Pages

Posted by Neil on October 16, 2013

Just a quick note that our NBA Playoff Series pages now have advanced stats tables, so you can learn that, for instance, Chris Andersen and Chauncey Billups both had Offensive Ratings north of 150 in this 2009 playoff series.

We also added Four Factors tables to the series summary pages, wherein you'll find nuggets like Phoenix's ridiculous 122.7 team Offensive Rating against the Warriors in this 1994 series. Enjoy!
