Introducing BPM 2.0

25th February 2020

Basketball-Reference is now utilizing BPM 2.0, an improved version of Box Plus-Minus. Like the original BPM, BPM 2.0 is a statistic created by Daniel Myers which aims to estimate a player's performance relative to league average by using a player's box score information and his team's overall performance. On the site, BPM 2.0 will appear just as BPM did. On player pages it can be found in 'Advanced' section with columns dedicated to OBPM (Offensive Box Plus-Minus), DBPM, (Defensive Box-Plus Minus), BPM (Box Plus-Minus) and VORP (Value Over Replacement Player). OBPM and DBPM, when summed, equal BPM. They are all rate stats. VORP is a counting stat since its inputs are BPM and playing time. As before, these statistics are all available back to the 1973-74 season (though we're hopeful to eventually extend the measure back to 1951), when critical statistics such as blocked shots, steals and offensive/defensive rebounds were first officially tracked. For the nitty-gritty details on BPM 2.0, please see Daniel Myers's explainer.

Box Scores Since 1904 & Play-by-Play Since 1918 Now on Baseball Reference

20th February 2020

Thanks to the efforts of our friends at Retrosheet, we have added box scores back to the 1904 season to Baseball Reference. Previously, our game log coverage was back to 1908. Additionally, we have added partial play-by-play coverage for games games as far back as 1918. Previously, our oldest play-by-plays were from 1925. Since our last major Retrosheet update, the final two missing full play-by-plays of 1973 were added which means we now have complete PBP data back to that season now. In addition to the boxes and PBPs themselves, this update allows for a variety of new information searchable in the play index, as well as new rows of information in team/player/league statistics tables.

Here are some examples of the new information/searches available on the site.

If you have any questions about our data coverage, you can always see it here.

We're very excited about these new additions and hope you enjoy them, as well. Please let us know if you have any comments, questions or concerns.

And thanks again to Retrosheet!

Every Buzzer-Beater in NBA History Added to Basketball-Reference

17th February 2020

After years poring over play-by-plays, watching videos (tough, I know) and reading thousands of game stories in newspaper archives, Basketball-Reference has compiled the first comprehensive list of every buzzer-beating game-winning shot in the history of the NBA and the BAA. To date, there have been 772 such shots in NBA history, including free throws with time expired. I'm defining game-winning buzzer-beaters as successful shots taken with the shooter's team tied or trailing which left no time on the clock after going through the net. These are true game-enders leaving no opportunity for the opponent to respond. As Tim Duncan knows, there are no such thing as game-winning buzzer-beaters that leave even 0.4 seconds on the clock.

Every Buzzer-Beater in NCAA Tournament History

6th February 2020

We have compiled every game-winning buzzer-beater in NCAA Tournament history. Since you cannot advance the ball to half-court with a timeout in college basketball, we have been lenient with how we define "buzzer-beating game-winner" and included all shots in the final 2.0 seconds of a game that put the winning team in the lead (so either tied or trailing at time of shot, and leading afterwards). However, it wasn't until the 1993-94 season that the clock automatically stopped on makes in late-game situations. Consequently, we have included some shots from 1993 and earlier that were made with more than 2 seconds left, but which left the opponent with 2 seconds or fewer left to respond by the time they chased down the make to inbound or call a timeout. An additional wrinkle is that the NCAA added tenths of a second to the clock for the 1990-91 season, but just had whole numbers for earlier seasons. One notable exception is Tate George's buzzer-beater against Clemson, since that was played in an NBA arena (The Meadowlands).

A few notes about how this data was compiled:

        • We read recaps or watched video of every NCAA Tournament game decided by three points or fewer. It's possible there was a game with free throws shot after time expired due to a technical foul (or something else) that we missed because the final margin ended up being 4+ points. Same with a three-pointer made at the buzzer on which the player was also fouled or a team that scored multiple times in the final two seconds.
        • The distances and assists listed are unofficial, gathered from play-by-plays, video review and newspaper accounts. Distances sometimes varied in different accounts, so we used the distances listed in the most comprehensive game stories we could find.

      If you have any additions to this data, please
      let us know

Headshots Added to College Basketball Reference

22nd January 2020

On our sites that cover the pro sports, we at Sports Reference make an effort to include portraits of the players being covered, as there is power to attaching a name and stats to a face. With that in mind, we're happy to announce both the addition of headshots for players currently participating in the 2019-20 college basketball season, as well as pictures for 500 major historical players.

If you're subscribed to our College Basketball Stathead daily recap newsletter, you may have noticed we recently added the headshots of the top 5 players for each night to give your inbox a splash of color. (And if you're not subscribed but are interested, sign up here!) Luka Garza, Markus Howard, Xavier Tillman, they've all got their faces on the site now.

As for the historical players, check out Bill Walton when he was playing college ball instead of commentating on it, or Tony Bennett's big smile back when he was shooting threes for Green Bay instead of coaching the Cavaliers. Charles Barkley when he had hair, or David Thompson rocking the 'fro at NC State are also choice additions.

We do plan to incorporate historical coach headshots in the near future as well. If you have any questions or suggestions, feel free to contact us through our feedback form. Thanks for following us!

Post-Shot xG for Goalkeepers Now on FBref

22nd January 2020

As part of our partnership with StatsBomb, FBref continues to incorporate more advanced statistics for players in the major international leagues. Additions have included expected goals, passing data and plus/minus, which you can read more about in this blog post. We have now added post-shot expected goals for goalkeepers, which uses expected goals on on-target shots to measure the shot-stopping ability of goalkeepers.

This information is available in competitions' advanced goalkeeping page. For example, here is a link to the advanced goalkeeping table for the 2019-20 English Premier League. You can read FBref's xG explainer as well as Statsbomb's PSxG explainer for more information on how these figures are calculated.

You can keep up with the latest additions of competitions coverage and new features here on the Sports Reference Blog, or by signing up for the This Week in Sports Reference mailing list. Feel free to send us any questions or suggestions through our feedback form or FBref's official Twitter account.

AP Player of the Week (1963-1973) Added to PFR

10th January 2020

The NFL began handing out Player of the Week awards in 1984, but before then the Associated Press handed out their own Player of the Week awards. Thanks to compilation work by John Turney, we now have that award's history from 1963 to 1973. Notably, before 1970 there was an AFL and NFL version of the award. Len Dawson and John Hadl lead the way with 8 AP Player of the Week honors. The AP was also liberal enough with its criteria to award entire units, such as the Raiders Linebackers in Week 2 of 1973, or the entire Fearsome Foursome of Merlin Olsen, Deacon Jones, Lamar Lundy and Roger Brown in Week 14 of 1967.

Check out the full list of Player of the Week recipients at Pro-Football-Reference.com. If you have any questions or suggestions, feel free to contact us through our feedback form or Pro Football Reference's official Twitter account. Thanks for following us!

We Have Details on 99% of Triple-Doubles in NBA History

27th November 2019

As we continue to make efforts to flesh out as many historical NBA box scores as possible, one of the benefits is being able to capture many of the most outstanding individual efforts in NBA history. A prior example is that we have shooting numbers for all but one 50-point game in NBA history. Recently, we were curious to see how robust our coverage of NBA triple-doubles is. We're happy to report that we believe we have details on 99% of the triple-doubles in NBA history (well, technically it's only 98.6%, but we'll round up).

Advanced Passing Revamp At PFR

20th November 2019

Earlier this season we announced our partnership with Sportradar to bring advanced offensive statistics to Pro Football Reference. We are happy to announce that for the 2019 season and beyond, we have now added additional advanced passing statistics to help provide context and key breakdowns for the quarterbacks around the league.

We can use MVP candidate Lamar Jackson as an example of the new statistics provided in the Advanced Passing table of quarterback pages. In the Accuracy tab, you'll now see batted passes and spikes in addition to previously added stats such as throwaways and bad throws. We also show passes on target and on target percentage, which ignores spikes and throwaways. Jackson has a 75.4 on target percentage in 2019.

In the Pressure tab of the Advanced Passing table, in addition to previously provided stats such as times blitzed, times hit, and scrambles, we also have pocket time for 2019. Jackson in 2019 has had on average 2.6 seconds in the pocket between the snap and throwing the ball or pressure collapsing the pocket.

In the Play Type tab of the Advanced Passing table, we provide breakdowns for run-pass option plays and play-action situations. Jackson has run 106 RPO plays this season, passing on 51 and rushing on his own for 52 of them. Jackson has run 87 play-action plays, throwing for 559 yards on those plays.

Finally, we already provided air yards information, but in order to paint a more complete picture we are now showing both intended air yards, which includes all pass attempts, and completed air yards. That information is displayed in the dedicated Air Yards tab of the Advanced Passing table.

In addition to displaying this information at the individual level, we have also implemented this tabbed approach on the team advanced stats page. As a team, the Saints lead the league in on target percentage at 81.9%. In terms of pocket time, the Chargers, Chiefs and Bengals trail with just an average of 2.2 seconds. Unsurprisingly, the Ravens and Cardinals have both run over 150 RPO plays, while no other team has even 100.

If you have any questions or suggestions, feel free to contact us through our feedback form or Pro Football Reference's official Twitter account. Thanks for following PFR!
