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.
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":
- There are a few games missing from the data that we are working to remedy.
- This release only includes individual players. Teams and a Play Index are under development.
- Corsi and Fenwick numbers are not scaled to 60 minutes as is standard. These will be added in the future.
- 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.
- 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:
With that in mind, we welcome any feedback and look forward to expanding this area significantly in the off-season.

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.

The pitching table is getting pretty wide on the team and player pages, so we've added a new little twist to our player pages (soon to be on team and league pages) where if you hold your mouse over the save column for a pitcher a little box pops up and it will show you the blown saves, save opps, save situations and holds for that pitcher. See the screenshot below.
This data is already on the "More Stats" page linked just above the pitcher's primary stats, but not everyone makes it onto those pages.

This is a subtle one, but as you may know play-by-play and ergo certain split data like platoon info and count data is not complete back to 1914. We have 100% of play-by-play back to 1973 and the 98%+ back to 1954. Details Here.
So we are now allowing you to exclude the split seasons from the Play Index Split Finder where incomplete totals may occur, so a pre 1973 platoon split, or a pre 1988 by count split.
See the location of this checkbox below.

Last night, I added FIP (short for Fielding Independent Pitching) to the site. This is a sabermetric stat for pitchers that approximates ERA without the effect of their team's fielding ability. FIP actually correlates to future ERA better than ERA itself making it a superior indicator of future performance.
The idea is that the pitcher most directly controls the number of walks, home runs and strikeouts that occur and that the batters and fielders have a bigger say on whether balls in play are turned into outs and that most pitchers' Batting Average on Balls in Play (BAbip) reverts to a league average from one year to the next.
FIP is (13*HR + 3*(BB+HBP) - 2*SO)/IP + Constant(year). The constant is set so the yearly avg FIP equals the yearly avg ERA.
FIP can be looked at exactly like ERA and is scaled to exactly the same league average as ERA, but it's range will be slightly smaller.
Often a player with a low FIP and high ERA will improve, while a low ERA and high FIP indicates a likely regression as more hits start falling. I've placed FIP next to ERA to make this comparison more obvious, but if it begins making the ERA lookup too hard, I may move it further right on the pitching tables.
I've also added FIP and K% to the Play Index Season Finder. Right now, I don't believe we will add xFIP given the inconsistency in batted ball data, but that could change.
Player with big gap in FIP and ERA: Ricky Nolasco.

Practice Shot Charts.
NBA.com has really upped the level of detail they've added, so we're trying to respond with the latest and greatest data we can get. We've recently come to an agreement with a number of franchises for access to their practice film and have begun breaking down scrimmage data.
Practice shot charts seem to us the next frontier in basketball analytics. This data will show you who's improving, who isn't, and who is working on new aspects of their game. It's especially useful for players without a lot of playing time.
Before we roll it out sidewide, we've prepared some sample charts.

For many of the Play Index searches, we've added an option that allows you to filter the results by whether the team won the WS, the Pennant or even just made the playoffs. Enjoy.

We've added win probability graphs to every Super Bowl, from I to XLVII, from exciting to not-so-exciting. For years prior to 1999, play times were extrapolated from drive start and end times listed in the NFL Gamebooks for those games. For example, if we know this 8-play Rams drive in Super Bowl XIV started at 7:25 and ended at 3:20 with a touchdown, we estimate that each play took roughly 35 seconds off the clock. These are imperfect estimates (obviously the clock will stop on an incomplete pass or an injury and certain plays take longer to run than others), but they are close enough to allow us to calculate a pretty close approximation of the win probability for that given moment.
