Adjusted Shooting Stats Added to Basketball Reference

1st June 2020

There's been much debate about the greatest players in NBA history of late. One of the most difficult things about ranking players in a league with 70+ years of history is that the game has changed a lot over the years. Sure, some of it has to do with the skill and quality of the players. But some of it also has to do with the quality of the balls, the floors, the rims, the training, the travel, the accommodations, available nutrition and pretty much any other variable you can think of. For a better idea of how the league has changed over time, please see this table of league averages for each season in the history of the NBA. As you can see, 2019-20 is the fifth straight season in which a new league-wide eFG% record has been set. There are clearly things at play here beyond just player improvement. Though today's players are certainly more skilled than the ones that produced a league-wide 27.9 FG% in 1946-47 (the first year of the NBA's 'official' forerunner the, BAA, which was objectively worse than the league it eventually merged with, the NBL).

To help bring a bit of objectivity to cross-era comparisons, we have added an Adjusted Shooting table to all player, team and season pages. These tables will show a player's shooting percentages and tendencies, as well as league-wide percentages and tendencies and then scale them. Like OPS+ on our baseball site it will be scaled so that 100 represents a league-average shooter. 125 is 25% better than average and 75 is 25% worse than average. These figures are obtained by taking the player's shooting percentage, dividing it by the league-wide shooting percentages and then multiplying it by 100. So 125 doesn't mean a player was 25 percentage points above average, but 25 percent above average. We are also publishing adjusted versions of 3-point Attempt Rate and Free Throw Rate to give a better idea of how often the player shot 3s or got to the line relative to their era.

Additionally, we have calculated Field Goal Points Added and True Shooting Points Added to show how many points each player scored above or below what a league average player would have scored given an equal number of field goal attempts or true shot attempts, respectively. This is to show which players combined volume and efficiency (or those that combined volume with inefficiency, for that matter).

Baseball Reference Awards Page Revamp

27th May 2020

Baseball-Reference's Awards index covers all the major awards MLB has established over the years. In the past, we had some awards combined, such as MVP and Cy Young, on the same page. We've recently made a change to our Awards page so that each award is now given its own table, which allows for providing more statistical context than we previously did in these sections. For example, here's a link to our updated Cy Young Award page; you'll notice that you can now sort by the different basic pitching stats, if you wanted to take a quick glance at highest ERA (LaMarr Hoyt in 1983) or most innings pitched (Steve Carlton in 1972).

Take a look at our Awards index and scroll through the pages of baseball history at Baseball-Reference.com! Please let us know if you have any comments, questions or concerns.

2010s All-Decade Team + HOF Monitor Updates

12th May 2020

The Pro Football Hall of Fame 2010s All-Decade Team was announced a while back, and Pro Football Reference now lists the team in its Awards section, as well as in the Awards table on player pages for those who were selected. This year's All-Decade team had the peculiarity of being released without a first-team/second-team distinction, the first time that's happened since the 1960s All-Decade team. With that, our Hall of Fame Monitor also made a small change to its methodology to accommodate this; you can read the formula used for that here.

Here's a look at some of the more interesting impacts All-Decade selections might have on Hall of Fame cases:

Running Backs: Adrian Peterson and Frank Gore were already on their way to Canton, but All-Decade selections greatly help LeSean McCoy, Marshawn Lynch and Darren Sproles' future cases. McCoy's HOFm score is now at 80.76, moving him ahead of current top eligible RB Roger Craig. Lynch's score is now 68.94, which puts him just below the lowest-scoring HOFers who played in the 1980s or later. Sproles took a major jump to 64.4 thanks to making the All-Decade team on offense and special teams, and now finds himself in the range of borderliners Ricky Watters and Shaun Alexander.

Wide Receiver: This position is a little more scattered in terms of predicting who ends up making it in, but Calvin Johnson, Julio Jones and Antonio Brown will appreciate having their names in here. Considering his off-the-field meltdown, Brown is the strangest HOF case, but on paper his HOFm score is now at 89.12, which puts him right next to HOFer Art Monk and within sniffing distance of Michael Irvin.

Offensive Line: Jason Peters gets a healthy boost as he approaches the end of his career, his new HOFm score putting him inbetween HOFers Rayfield Wright and Orlando Pace, as well as right next to perennial finalist Tony Boselli. Jahri Evans and Marshal Yanda also got elevated into the mix of HOF guards with this selection.

Defensive Line: Calais Campbell gets some help for his HOF case with this selection, putting himself in the range of the highest borderline defensive ends like L.C. Greenwood and Neil Smith.

We hope you enjoy this addition and use it as a reference in friendly debates to come. Please let us know if you have any comments, questions or concerns.

2020 KBO Stats on Baseball-Reference

7th May 2020

The Korea Baseball Organization had their Opening Day this week, and Baseball Reference will be tracking 2020 KBO stats as the season moves forward. In addition to the current season, we have filled in our site's KBO history. Now we have individual and team batting and pitching statistics back to the league's founding in 1982, as well as fielding statistics back to 2001.

You can now back and look at MLB players who made a stop in KBO, such as Julio Franco's 22-HR, 110-RBI season in 2000 (at age 41!), or Eric Thames' 3 seasons with the NC Dinos before making his MLB return with the Milwaukee Brewers.

As for current players to look out for, you have former Minnesota Twin ByungHo Park, who already hit a home run on Opening Day this week and is hoping to notch another 30-HR KBO campaign under his belt. Keep an eye on veteran Kia Tigers pitcher Hyeon-jong Yang, who had one of his best years in 2019. Recent MLB players who are making their KBO debuts in 2020 include White Sox/Brewers infielder Tyler Saladino and journeyman starting pitcher Dan Straily, his last MLB appearance coming with the Baltimore Orioles.

We're excited to keep track of another active baseball league (check out our 2020 CPBL statistics as well!). Please let us know if you have any comments, questions or concerns.

Game-Level BPM In Play Index + Box Score Mouseovers

4th May 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

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!

2020 CPBL Stats on Baseball-Reference

14th April 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)

13th April 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
