Play Index Tools Now with Short Surveys & no Ads

8th October 2014

Since we've launched the various Play Index tools on our sites, we've struggled with the best way to monetize what we feel is the deepest and most powerful set of sports data tools anywhere. We know they are useful, our users, the teams, broadcast networks, and newspaper reporters tell us so.

On baseball, we charge an annual fee of $36, but our best guess is that the traffic and audience of the other sites would not be sufficient to make a subscription model worth our while. We have been running traditional banner ads on those pages, but they pay so little and the play index content is niche content (valuable, but niche content) so the traffic will never rise that high on the play index pages. So we have decided to remove all banner advertising and instead run Google consumer surveys on the non-baseball play index pages.

Here's how it works. The first time you run a report each day your results will be obscured and you will be asked to answer a 1-5 question survey. After you answer the survey, your requested report will be shown to you and you won't see another survey for that site on that browser for 24 hours (multi-question surveys are good for 48 hours). These surveys pay us around 5 cents per survey which, while it doesn't sound like much, is about 15 times what we would get from banner ads on those pages. Here is an FAQ if you are wondering how Google uses this information.

Also, if you find these gateway surveys a step too far, consider subscribing to our Ad-Free Access. Starting at $20/year you can surf every Sports Reference page ad and survey free.

If you are wondering what our play index tools are, give them a try. We think you'll enjoy them.

Introducing Shooting Splits With Particular Lineups

8th October 2014

Earlier this week we introduced new advanced search options into our shooting splits tool.

In case you didn't know before, we have detailed shooting data for every player since 2000-01, and detailed splits are available by going to a player's page and hovering your mouse cursor over 'Shooting':

 

shooting_link2

 

Now, you can click on the [+] next to 'show advanced options' and you'll see two new advanced tools.

On the left, type in a player's name and click the search result to add it. In most cases, it will automatically populate as 'As teammate' or 'As opponent'. This will show shooting splits for whoever's page you are on, with the selected player both on and off the court.

In fact, you can even add several players and select custom combinations of 'On' and 'Off'.

Check out how LeBron fared versus Kawhi Leonard in 2013-14 by adding Leonard's name, then clicking on 'Go to Page'.

You can check out the numbers for just the Finals by clicking on the 'Playoffs' link in the results (likewise, you can add any split to your query the same way).

Why did Ruben Patterson call himself "Kobe Stopper". It might be these 2001-2002 numbers when Kobe went 18-63 with Patterson on the court, then 46-96 with him off:

ALSO! The tool on the right lets you compare the player whose page you are on versus any other player, or any other season. It works the same way, that is, begin typing the name in the form and then click a season from the select box that appears.

Then click 'Go to Page' and you'll get a side-by-side comparison of that player's shooting splits versus his own or another player's, in whichever season you selected:

Situational Rate Stats on Hockey-Reference.com

25th September 2014

As part of our plan to continue to add "advanced" stats to the site, we've included new rate stats on the "Additional Stats" pages for players. These new stats are primarily "per 60 minutes" versions of already existing stats, but we also have included a break out of assists to include both 1st and 2nd assists per 60 minutes. The advantage of the "per 60" versions of these stats is that it makes it easier to compare players with wildly varying amounts of ice time.

 

Screen Shot 2014-09-25 at 8.14.59 AM

These stats are available by clicking on the "Additional Stats" link on the player pages:

As always, we appreciate any feedback or questions.

The Real Problem with Baseball’s Defensive Stats

8th September 2014

After reading Jeff Passan's article about WAR and his view of its failings, I got a little hot under the collar and intemperate in my discussion of the issue on twitter.

The defensive metrics are constantly critiqued. I agree that there may be issues with the defensive stats, but my issues aren't the ones brought up by the critics. I believe that the metrics do a decent job of measuring the percent of time a particular ball with a particular hang time has been caught in the past. All you need for that is a stopwatch and a way to mark the play's location on the field. Sure there may be biases in this, but there are biases in who batters and pitchers face or even what umpire they appear against. So this isn't the biggest issue with fielding stats.

It's also true that fielding stats don't correlate quite as strongly year to year as the batting stats do (see chart after break), but there is also a lot more variability in opportunity for fielders than for batters (and more variability in batting stats than people perceive). A batter is going to get 3-6 PA's per game every game. The distribution of balls hit to fielders is much more random. But even this isn't the big issue with fielding stats.

More #FancyStats Features Added to Hockey-Reference.com

3rd September 2014

It's been a while since we last announced new "advanced stats" features to Hockey-Reference, but with the latest shake ups in the hockey stats world, we felt that this was a good time to begin rolling out new features for the more statistically-minded fans out there. This is by no means the only roll out, as there are numerous features to come, but we feel it is better to roll out features as we complete them rather than waiting until they are all done.

That said, here's what we've added:

1) Additional Possession Stats to the Player Additional Stats Page

Screen Shot 2014-09-03 at 12.21.15 AM

We've added Situational TOIRelative Corsi For %, Relative Fenwick For %, On-Ice Save and Shooting %, and Offensive and Defensive Zone Start %. You can find these on any player page after 2006 by clicking on Additional Stats at the top of their regular stats.

Screen Shot 2014-06-05 at 3.26.02 PM

2) A Play Index Finder for Team Advanced Stats

Until we can add additional stats to all of the league and team pages, we've created a simple Finder that allows you to run queries against the team advanced stats. To find this tool, just go to the top-left menu and click play index, then Team Advanced Stats Finder. This report can be run on any or all teams from 2007-2014.

Screen Shot 2014-09-03 at 12.30.12 AM

3) Finally, as a small addition to the play-by-play stats, we've included Faceoff Wins and Losses.

We hope you enjoy these new features and keep checking back often as we add more #FancyStat features as we approach the new season. As always, we appreciate any questions and feedback.

Additional Possession and Play-by-Play Enhancements on Hockey-Reference

17th June 2014

As I mentioned a couple of weeks ago, we continue to work on our possession and play-by-play stats, and we have released the next enhancement, additional situations.

As a brief primer on what the new situations mean:

  • All Situations, Even Strength, Power Play, and Short-Handed are the traditional situations and mean what you expect them to.
  • 5-on-5 is situations where there were five skaters on the ice for both teams. It is similar to Even Strength, but doesn't include 4-on-4.
  • 5-on-5 Close is situations where there were five skaters on the ice for both teams and:
    - The score is within 1 point in the 1st or 2nd Period, or
    - The score is tied in the 3rd Period.
  • 5-on-5 Tied is situations where there were five skaters on the ice for both teams and the score was tied.

When you click on a situational tab, all of the stats on that page are for that situation (Blocks, Hits, Corsi For, etc.).

Where are they?

To find these stats, go to a player's page (one who's played in a game since the 2007-08 season) and you will see a link to "Additional Stats":

Screen Shot 2014-06-05 at 3.26.02 PM

Clicking on that will take you to the Additional Stats pages where you can see these new enhancements.

We welcome any feedback or questions you have about these new features.

Introducing Per 100 Possessions Statistics

17th June 2014

If you've been browsing recently, you've may have noticed that we added per-100 possession statistics tables to the player pages and team pages (and for both the regular season and playoffs). For now, we're able to estimate team possessions going back to the 1973-74 season.

We also have league-wide tables that correspond to those on the player and team pages, with stats for every player, and even totals for all individual team stints for those players that were traded, re-signed, etc. Sometimes users tend to not to find these but they're extremely useful for sorting or exporting and doing your own analysis.

Here's the easiest way to find those tables: Mouseover the 'seasons' link and click on Per Poss on the dropdown menu:

 

per_poss

 

(Similarly, these are available for the playoffs, as well - corresponding links can be found in the 'playoffs' site section)

 

Per-Possession statistics are an easy way to nullify the distorting effects of pace and compare players more easily across teams and eras. For the record, we estimate league pace going back to the 1973-74 season using the formula provided in our statistics glosssary, and estimate it for individual teams going back  to 1950-51 by estimating component statistics.

Beta Play-by-Play Stats Now Available for Players on Hockey-Reference

5th June 2014

We are beginning to release some new stats on Hockey-Reference that we are lumping together into "Play-by-Play Stats". In this initial release, we are including basic counting stats on the player level -- like Hits, Blocks, Takeaways, and Giveaways -- as well as possession stats like Corsi and Fenwick.

Screen Shot 2014-06-05 at 3.27.14 PM

We intend to provide a full introduction to all of these new stats on the site before they come out of beta, but for now take a look at this article over at Grantland. These stats come with a few of caveats, which is why they are being released as "beta":

  1. There are a few games missing from the data that we are working to remedy.
  2. This release only includes individual players. Teams and a Play Index are under development.
  3. Corsi and Fenwick numbers are not scaled to 60 minutes as is standard. These will be added in the future.
  4. The Corsi/Fenwick numbers are only provided for Even Strength situations. Other situations (e.g. SH, PP, 5-on-5 close, etc.) will be provided in the future.
  5. This data only goes back to the 2007-2008 season.

To see these new stats, simply go to a player page of someone that has played since the 2007-08 season and click on the "Additional Stats" tab in their NHL Stats table:

Additional Stats

With that in mind, we welcome any feedback and look forward to expanding this area significantly in the off-season.

Team Positional Comparison Tool–in our opinion it’s pretty cool – Baseball-Reference.com

30th May 2014

Positional differences and performance by position are interesting ways to look at team performance. For instance as Phillies fan I know that CF and LF are hurting the Phillies, but just how much are they hurting relative to the league. This tool answers that question and many many more. (answer: a whole lot of hurt)

You select a year, the league and a stat, and we rank every team at each position by that stat and in some cases a summary of positions. This uses our positional splits to allot stats to positions or in some cases a prorated assignment of WAR and related stats by time played at each position. Now in one table you can see the worst or best team-positions in baseball.

There are some additional tools that allow you to highlight a particular team and mousing over a table cell informs you the players involved in producing that value.

I like this output so much I've also added it to our base league pages just below the pitching stats.
