Pro Football Reference is pleased to announce that it has added full game-by-game (and also year-by-year) Sack Yards Lost data for all passers (NFL, AFL and AAFC) back to 1947, which was the first season Sack Yards Lost were tracked separately and not merely removed from rushing yardage (which is why many passers before 1947 had negative rushing yards).

In June Pro Football Reference extended its game-by-game coverage of player fumbles, fumbles recoveries and fumble return yards back to 1989. Today we're happy to announce that we've added two more seasons of coverage (1988 and 1987) thanks to the research of Ken Pullis. In 1988 Randall Cunningham led the NFL with 12 fumbles. You can now see which games those came in in his game logs for that season. Similarly, you can see Dan Marino's league-leading eight fumble recoveries in his game logs. Fumble return yardage also shows up in the game logs back to 1987. Such as Reggie White's 70-yd return in 1987 against Washington. This information also appears in the box scores.

We've added a brand new stat to PFR. It's Success Rate, one of the coolest and most interesting new advanced stats to enter the football discussion in the last few years.
Success Rate starts with the idea that not all plays in football have the same objective. On first and 10, a two-yard run would be considered a bad result; on third and one, that same two-yard run would be celebrated for moving the chains. This means we can't just use stats like yards to measure how effective an offense is. Instead, Success Rate shows us how effective players and teams are at staying on schedule and creating productive plays.
As a result, a successful play depends on the context. We define it as a play that gains at least 40% of yards required on 1st down, 60% of yards required on 2nd down, and 100% on 3rd or 4th down.
As mentioned, it can be measured for both players and teams, for passing, rushing, and receiving. For example, here are the leaders in 2022 in rushing yards per attempt:
And here are the leaders in rushing success rate:
There's some overlap, of course, but also some key differences. Josh Jacobs averaged 4.9 yards per attempt, outside the top 10, but situationally he was one of the best RBs in the league last year. Meanwhile, Justin Fields averaged the most yards per attempt, but his scrambles and designed runs were less effective at keeping the team on schedule than QBs like Lamar Jackson, Josh Allen, or Jalen Hurts.
Success rate is also in Stathead! Our historical data goes back to 1994, when we first have play-by-play data to calculate this, so you can look up career leaders, single season leaders, rookie leaders, single-game leaders, and more.
This was one of our most requested adds; we love user feedback! If there's something you'd like to see on the site, please let us know!

Thanks to the research of Ken Pullis, Pro Football Reference has added game-by-game coverage of player fumbles for the 1989 season. For instance, you can now see which games all of Randall Cunningham's career-high 17 fumbles occurred in in the 1989 season via his 1989 gamelogs.

Last fall Pro Football Reference added a suite of new punting statistics going back to 1976. We have recently extended many of these statistics back to the 1970 merger thanks to the work of Pete Palmer and Ken Pullis.
This means that we now have coverage for return yards against, net punting yards, net yards per punt, touchbacks and touchback% for all punters back to 1970. Punts inside the 20 coverage, however, still only extends back t0 1976. Bobby Walden's page is a good example of the variable statistical coverage for punters since he punted from 1964 to 1977. You'll notice 1976 and 1977 have the broadest statistical coverage but that 1970-75 is now nearly on par with 1976 and beyond. Pre-merger punting stats, however, remain limited to punts, punt yards, long punts, etc.

Thanks to the work of researcher and former NFL official scorer Pete Palmer and fellow research Ken Pullis, Pro Football Reference has made slight fixes to 150 player single-game passing, rushing or receiving totals in the 1960s. For NFL games, these were generally changes that we made after the fact and impacted some single-game totals for teammates. Most of the fixes were in the AFL from 1960-1965. No team or season NFL statistics were changed.

All our player pages recently received a big update. We added a new table showing every player's performances over their last five games. It looks like this:
Pretty cool! This is on all sites (except FBref, where it's still in development), but right now you can only see it on the sports that are currently in season.

We're excited to announce a new tool for Stathead Football, and it's one of our most-requested features.
The Player Span Finder gives you the power to search for player stats over any consecutive span of games from any point in their career. We've often had users ask for tools to answer questions like "Who had the most passing touchdowns in any 16 game span since the merger". Now, with the Span Finder, you can look that up. Unlike the Streak Finder, it will give you cumulative stats over every game in the span, regardless of if it fits the streak. And unlike the Game Finder, it can search every single possible span.
