Today, we're thrilled to announce that Stathead Football has joined our suite of Stathead tools, the most powerful set of sports research tools available to the public. In fact, they're so good that the pros (whether they're running teams or covering them) also swear by them.

Gap Years on Basketball Reference

14th August 2020

Thanks to work from summer intern Amy Huddell and the research of APBR President Emeritus Robert Bradley, Basketball Reference has greatly expanded its database of gap years for NBA players. Specifically we've added 704 new records in addition to the previous gap year data we had on the site. This includes mid-season career interruptions, first-season injuries and situations where they were still on the roster for their final season but did not play.

Often mid-season career interruptions are injury-related, such as Derrick Rose's ACL in 2012-13 or Greg Oden's various knee ailments. Occasionally there are other reasons like Robert Reid in 1982-83 voluntarily retiring to pursue the ministry or Red Morrison in 1956-57 who went into the construction business before making a return the next season. There are a couple of players such as Charlie Paulk and Dick Rosenthal who had gap years due to military service.

Notable end-of-career notes that we've added include Wilt Chamberlain sitting out his final year under contract with the Lakers and Alex Groza being suspended indefinitely for his involvement in the CCNY point shaving scandal.

Another gap year situation is players in international leagues between getting drafted and making their NBA debut, or players extending their careers internationally. Recent examples of this that were added in this batch include Patrick Beverley and Stephon Marbury.

We hope that adding this context to player pages helps people browsing the site understand their careers a little better. Thanks again to Amy Huddell and Robert Bradley for their help with this project. If you have any questions or suggestions, feel free to contact us through our feedback form.

Box Scores Since 1901 Now on Baseball-Reference

24th July 2020

As we were getting ready for 2020 Opening Day, the hard workers at Retrosheet announced their latest update, and we have gotten that new information added to Baseball-Reference as well as our Stathead Baseball tools. The highlight from the latest Retrosheet update is the addition of box scores from 1901 to 1903. This means that we now have box scores for every game in American League history, as the AL's first season was played in 1901. Retrosheet has also uncovered play-by-play accounts for games in 1916 and 1917, extending PBP coverage two more years back, although we should note 100% coverage remains limited to 1973-present. The new play-by-play allows us to further bolster our historical splits and event data.

With game log coverage back to 1901, we now have game logs for the entire careers of Hall of Famers Johnny Evers, Joe Tinker and Mordecai "Three Finger" Brown. We also now have the box score for Christy Mathewson's first no-hitter of his career, on July 15, 1901. Our Stathead Game Finder tools can now search back to 1901 as a result, and Mathewson appears as the 3rd pitcher in that time span to throw a no-hitter before their 21st birthday. Batting and Pitching Event Finder searches have been opened up back to 1916. Of the games we have PBP for in 1916 and 1917, Bill Hinchman leads with 3 walkoff hits in that span. Advanced stats tables that rely on play-by-play will also be extended back to 1916.

If you have any questions about our data coverage, you can always see it here. We're happy to have this new data on our sites and hope you enjoy it as well. Please let us know if you have any comments, questions or concerns.

And thanks again to Retrosheet!

NCAA Tournament Starters Complete Back to 1977

16th July 2020

Thanks in part to work from our intern Ryan Sullivan, College Basketball Reference now has starter and reserve designations for all NCAA Tournament games back to 1977. We previously could only claim 100% starter/reserve data back to 1994. Of course, this supplements our Final Four starter/reserve data which is already complete back to 1955. This data can be searched in our NCAA Tournament Player Game Finder.

Some searches that can be updated with these additions:

- Sean Higgins joins the list of reserve players with 30 points in a game, reaching that mark in the Elite Eight of the 1989 NCAA Tournament. He also joins the list of players with 100 points off the bench in their tourney careers.

- Reggie Theus is one point shy of Donte DiVincenzo for most points scored as a reserve in a single tournament, in 1977 with UNLV.

We hope you enjoy this addition to the site. Please let us know if you have any questions or comments.

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).

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.

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

18th April 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.
