Game-Level BPM In Play Index + Box Score Mouseovers

Posted by Alex Bonilla on May 4, 2020

In February, Basketball Reference made a major update in incorporating Daniel Myers' BPM 2.0, 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. This statistic is also calculable at the game level, and we've made it easier to look through this by making BPM searchable in Basketball Reference's Game Finder, one of the many tools you can find in the site's Play Index.

BPM 2.0 is searchable back to the 1984-85 season, when we first have 100% coverage of all the statistical components needed to calculate this. It's important to note that BPM is a rate stat, so setting a minutes played threshold will be important. Here's a look at the top games in our system using a couple of different thresholds:

Minimum 10 MP

Query Results Table
Player Date Tm MP TRB AST PTS BPM
James Robinson 1996-12-30 * MIN 10 1 1 23 74.6
Henry James 1997-04-15 * ATL 10 2 1 24 63.9

Vince Carter 2001-05-11 * TOR 45 6 7 50 34.0

In addition to the Game Finder addition, Basketball Reference now has mouseovers in the advanced section of box scores that display the offensive and defensive BPM breakdowns, as well as Value Over Replacement Player prorated to 82 games. For more information on how BPM 2.0 is calculated, please consult Daniel Myers' explainer. Stay tuned to the Sports Reference Blog for the latest additions to Basketball Reference!

Launching Stathead

Posted by sean on April 27, 2020

If you haven't read it already, please read Mike Lynch's rundown of our new Stathead/Baseball service. I'm going to lay out some of the background for this change and explain some of the changes.

As I laid out in our post from early March, we are making changes to our Ad-Free and Play Index products.

Here is the thrust of what we said in March.

So we are making some changes. The Play Index for each site will be moving to Stathead.com. Stathead.com will become the center for all of our subscription products. We expect these products to include tools and information beyond just a redesigned set of Play Index tools. This won't happen all at once, but we'll start with baseball and then proceed through the remainder of our sports. Also, we will be ending our ad-free product and instead Stathead memberships will have ad-free built-in. There just aren't enough users to justify a separate ad-free product. These changes will begin this month and continue through April on baseball and then continue with the other sites after that.

If you are a subscriber, we will make every effort to make certain you are happy with the options we provide to convert your ad-free or Play Index subscription over to Stathead including the option of a refund on your subscription. You will be hearing more from us about the changes over the next few weeks as we will email users directly.

If you've looked at the cost of Stathead/Baseball vs the Play Index, you'll notice we've gone from $36/year (+ $20/year for ad-free) to $8/month. I realize this is a significant increase. As I said in my original post, we are extraordinarily reliant on ad revenue. Back in early March this seemed problematic. Now with the complete collapse of the advertising market it has the potential to be lethal. If you don't block our ads, you may have noticed that we now have more ads on our pages. This is in response to the downturn in ad revenue. Sports Reference is doing fine right now, but if we want to continue to succeed and also be aligned with the needs of our users, a healthy stream of subscription revenue is vital.

We also feel our products warrant this price. The only comparable products to our Stathead tools come from Elias and STATS LLC and would cost you $10,000+ a year to subscribe to. You could create your own from Retrosheet data, but that would probably take more than $8/month of your time to maintain.

We are using monthly billing for at least the first few quarters, so that we can monitor more directly the success we are having in recruiting and maintaining subscribers. We have discussed adding an annual billing option in the future.

For the time being, we will be maintaining both the legacy Play Index site (which has been free since the start of March) and the new site, but before too long we will take down the old Play Index site, probably late May. We are also working on converting the other Play Index sites. First will be hockey and then probably basketball after that.

We realize there aren't games being played and that you might be facing your own financial challenges at this time. Therefore, we are offering the first month free for all users. And then, until the leagues start playing games, we will be giving users the option of claiming additional free monthly subscriptions. We'll provide more details on the latter plan as we approach the time for subscriptions to be renewed.

If you are a current subscriber, we will be emailing you with information about how we will be converting your subscription to the new system and of course, we will provide your money back if you are unhappy with the conversion to Stathead that we are offering you. Our goal is to give you a more than fair deal and see you join us on stathead.com.

Please feel free to reach out to us if you have questions or concerns.

NCAA Season Averages Table on College Basketball Reference

Posted by Alex Bonilla on April 27, 2020

On the Sports Reference sites that cover professional leagues, we have tables that track team averages in various statistics over the league's history so people can get a sense of how stats have gradually changed as their respective sports evolved. You can see examples of this on Basketball Reference and Pro Football Reference.

We've added this feature to College Basketball Reference so you can see the averages for all Division I schools since 1947-48. The Teams column shows the growth of Division I from less than 150 teams in 1950 to 350 teams in 2020. You can also see the gradual rise in teams' usage of the three-pointer, mirroring its growth in the NBA, as well as the gradual decline in turnovers committed over the past three decades.

Please check out the new game averages table at College Basketball Reference, accessible from the site's Seasons Index. If you have any questions or suggestions, feel free to contact us through our feedback form.

NBA Play-By-Play, Lineup and Shooting Stats Added Back to 1996-97

Posted by Mike Lynch on April 18, 2020

Last August Basketball Reference extended its coverage of play-by-play all the way back to 1996-97 (the earliest season for which comprehensive, digitized NBA play-by-play data is available). As we teased at the time, we hoped to use the play-by-play to build out other features. In October we added the ability to break down our box scores since '96-97 by the quarter or half. Today we're happy to announce that many features that we've had available back to 2000-01 for many years have now been extended back to 1996-97.

You can look through our blog's FBref tag for a look at the most recent additions we've made to the site, and today we have another mass addition of advanced stats you can now access on player pages. Here's the list:

Passing

- Progressive Passes

Pass Types

- live-ball, dead-ball, under pressure
- corner kick types (in-swinging, out-swinging, straight)

- by body part (left/right foot, head, throw-ins, other)
- pass outcomes (completed, offsides, out of bounds, intercepted, blocked)

Goal and Shot Creation

- Goal Creating Actions (GCA) and Shot Creating Actions (SCA), meaning the two offensive leading to a shot or goal. This includes live-ball passes, dead-ball passes, successful dribbles, shots which lead to another shot, and being fouled

Defensive Actions

- tackles by location on pitch
- pressures, successful pressures, pressures by location on pitch
- blocks (shots, shots saved, and passes)

We're excited to see what analysis people can derive from this new information, which is available thanks to the hard work of Statsbomb. You can keep up with the latest additions of statistical coverage and new features here on the Sports Reference Blog, or by signing up for the This Week in Sports Reference mailing list.

2020 CPBL Stats on Baseball-Reference

Posted by Alex Bonilla on April 14, 2020

With the current state of sports being mostly halted due to coronavirus concerns, the Chinese Professional Baseball League is in a rare position as they had their Opening Day and are planning to fill a regular schedule, albeit without spectators. Baseball Reference tracks various foreign leagues already, and we're happy to report that we will be receiving 2020 CPBL statistics as the season moves along.

The first game of the season was a win for the Uni-President 7-Eleven Lions over the Chinatrust Brothers. The Lions' Opening Day starter on the mound was Ryan Feierabend, who pitched for the Toronto Blue Jays in 2019. Former Seattle Mariner Ariel Miranda was the Brothers' starting pitcher. The only homer of the game was launched by Kai-Wen Zheng, who's been with the Lions since 2016.

We've also filled in CPBL history so now we have player stats for the league since 1990. For example, on Manny Ramirez's page we finally show his .352/.422/.555 campaign in 2013 with the EDA Rhinos (at age 41, no less).

2020 CPBL statistics will be updating daily so keep up with the league on Baseball-Reference! Please let us know if you have any comments, questions or concerns.

Change to 1880 Cincinnati (NL)

Posted by Alex Bonilla on April 13, 2020

When the National League was founded in 1876, one of the inaugural teams was the Cincinnati Reds. They folded a couple of years later, and the team we know as the Reds today would be founded in 1882. Previously, we had the inaugural Reds franchise as lasting to the 1880 season before folding. However, after research presented by Jim Farmer and consultation with John Thorn and Retrosheet, we've decided to mark 1880 Cincinnati as a different franchise named the Stars, with the inaugural Reds having ended after the 1879 season.

Putting it another way:

BEFORE

Cincinnati Reds (old): 1876-1880
Cincinnati Reds (new): 1882-present

NOW

Cincinnati Reds (old): 1876-1879
Cincinnati Stars: 1880
Cinncinati Reds (new): 1882-present
