PI Finds: Final 2010 Team Adjusted Rushing Yards per Attempt, SRS-Style

Posted by Neil Paine on January 6, 2011

As a follow-up to the 2010 team passing ratings I posted Tuesday, I ran the same process on team rushing performances. The formula for adjusted rushing yards per attempt was:

ARY/A = (Rush Yds + 18 * Rush TD) / Rush Att

(The 18 comes from Chase's post on the value of TDs.)

Using the PFR Team Game Finder, I plugged every team single-game rushing performance of the 2010 season into the formula above, then adjusted for strength of schedule and game location using an SRS-style recursive loop. The result was a set of ratings that best predicted every game according to these equations:

Home ARY/A = Lg Avg  ARY/A + .5*HFA + Home Rush Offense Rating + Away Rush Defense Rating

Away ARY/A = Lg Avg ARY/A - .5*HFA + Away Rush Offense Rating + Home Rush Defense Rating

Here were the ratings (again, negative is good for defenses):

In a move that's admittedly long overdue, we've added Doug's Approximate Value metric to a variety of places throughout the site:

And as always, you can search for AV leaders using the PFR Play Index's Season Finder (example).

Also, we overhauled the main AV page to make it more user-friendly, added a sub-page for Doug's extended explanation of the method, and created a blog category for AV to make it easier to find past and future posts that feature the stat.

PI Finds: Most Overtime Games by One Team

Posted by Neil Paine on December 1, 2010

Today we have an inquiry from PFR reader Jose:

"No one seems to know the answer to this question: What is the record for most OT games in a season by one team?"

Thanks to an upgrade made to the Play Index Team Game Finder by S-R president Sean Forman, we can now use PFR's site tools to answer this question.

Just go to the Team Game Finder, select "Search for Season Games matching criteria," and check the OT radio button at the bottom left-hand side of the finder interface ("Overtime Game"=Yes). Click "Get Results," and here's what you come up with:

Rk Tm Year W L T W-L% Count
1 Carolina Panthers 2003 4 1 0 0.800 5

PI Finds: Searching for Vick/Eagles Milestones at PFR

Posted by Neil Paine on November 17, 2010

If you were watching the Philly-Washington game on Monday night, you knew that Michael Vick and the Eagles were setting records right & left because the MNF crew pointed them out on-screen as they happened. But do you ever wish you could search for those kinds of milestones yourself? Using the Pro-Football-Reference.com Play Index, you can. Here are some Vick/Eagles milestones I searched for on Tuesday morning, as soon as we loaded the Eagles game into the database:

(Please note that I'm not picking on the Redskins here, or rubbing in their loss -- this is merely a demonstration of our site tools, and the MNF game is a good example because a lot of milestones were reached.)

PI Finds: The Rivers Index

Posted by Neil Paine on November 11, 2010

Last week, I showed you how to set up an "expected W-L" method for a quarterback using the Play Index Team Game Finder, the QB's gamelogs, and a logistic regression formula. I found that our test case, Philip Rivers, should have been expected to win 27.7 games over the last 3 seasons (prior to the Chargers' win over Houston) based on his passing performance, but in actuality only won 24 games, a difference of -3.7 wins. Without context, though, that number doesn't really mean anything -- is that a lot, or a little? Today, I'm going to answer that question by comparing every QB's actual and expected W-L records, something I like to call "The Rivers Index" (in an homage to Doug's Manning and Dungy Indices).

PI Finds: Should Philip Rivers Have Won More Games?

Posted by Neil Paine on November 5, 2010

Using the PFR Play Index's Player Season Finder, you can run custom individual leaderboards across multiple seasons. For instance, here are the NFL leaders in Adjusted Yards per Attempt over the past three years:

Rk Player From To Tm G Cmp Att Yds TD Int AY/A
1 Philip Rivers 2008 2010 SDG 40 827 1270 10912 77 27 8.85
2 Drew Brees 2008 2010 NOR 39 1010 1480 11791 84 39 7.92
3 Aaron Rodgers 2008 2010 GNB 40 856 1346 10483 70 29 7.86
4 Tony Romo 2008 2010 DAL 35 771 1213 9536 63 30 7.79
5 Matt Schaub 2008 2010 HTX 34 796 1198 9552 54 31 7.71
6 Tom Brady 2008 2010 NWE 24 525 801 6076 40 17 7.63
7 Peyton Manning 2008 2010 CLT 39 961 1425 10686 75 30 7.60
8 Ben Roethlisberger 2008 2010 PIT 34 670 1057 8383 48 29 7.60
9 Kurt Warner 2008 2009 CRD 31 740 1111 8336 56 28 7.38
10 Donovan McNabb 2008 2010 TOT 38 771 1291 9440 52 29 7.11

As you can see, the leader (by far) is San Diego's Philip Rivers. In fact, 10th-ranked McNabb is closer to #2 Brees than Brees is to Rivers!

Statistically, it's tough to find a QB since 2008 who can touch Rivers. However, his team hasn't enjoyed the same lofty success: the Chargers are 24-16 over the past 3 years -- a respectable record, but one seemingly out of place next to Rivers' gaudy passing numbers. This disconnect between individual accomplishments and team performance has haunted many a quarterback in the past, and is now is the main reason Rivers isn't held up in the same group as Brady, Manning, Roethlisberger, and Brees as a quarterback. QBs are supposed to win, we're told, not amass seemingly empty stats.

PI Finds: Not Your Typical 6-1 Pats

Posted by Neil Paine on November 1, 2010

Stop me if you've heard this one before: At 6-1, the New England Patriots boast the NFL's top record despite a roster that looks less than overwhelming on paper. So does this mean 2010 will be another one of those patented Patriot seasons where they're somehow on top when the dust clears? Let's go to the PFR Play Index's Team Game Finder and break down the numbers...

Tony Romo’s career stats aren’t as misleading as I thought

Posted by Chase Stuart on August 23, 2010

If you go to PFR's leaderboard page, you can see that Tony Romo ranks 4th all time in yards per pass attempt, and all three quarterbacks ahead of him retired by 1960. Romo also ranks first in net yards per attempt (PFR has NY/A data beginning in 1969, which is the earliest year for which we have complete individual sack data) and first in adjusted net yards per attempt among all players. You can use PFR-'s play index to see a list of the top active quarterbacks in yards per attempt, and I've heard multiple sources cite Romo's incredible career average in that category.

My initial take when I heard such propaganda was that is was incredibly misleading. Why?

1) Romo obviously plays in a much more pass-friendly era than nearly every quarterback in league history.
2) Romo, because he was an undrafted free agent, didn't see the field during his early years. Young quarterbacks tend to play poorly, and sitting on the bench during your first couple of years will help boost your career averages, especially when you have only played for a few seasons. Which brings me to ...
3) Romo just turned 30 years old in April; he hasn't yet played during the final years of his career, when most quarterbacks tend to kill their career averages. For example, the Patriots Steve Grogan retired with a career yards per attempt average of 7.48, but from age 25 to 34, Grogan averaged 7.98 yards per attempt. Romo, unless he retires early, will sink his career averages at least a little bit by the end of his career.
