Here is a google doc containing every team-season in our database since 1957, including the Head Coach and offensive & defensive coordinators. It also specifies those coaches' preferred offensive or defensive schemes (depending on which side of the ball they specialize in), and attempts to figure out the general offensive family (i.e. Air Coryell, Erhardt-Perkins, etc) each team-season fell into.
THIS IS BY NO MEANS COMPLETE. In fact, it's very much incomplete at this stage -- and that's where you come in. In the comments of this post, or in an email, we'd love to hear corrections and/or additions to the data, if you see an entry about which you know more than we do (and it's a good bet you do). Thanks in advance for your help, and hopefully we can assemble a more complete listing of teams' systems/schemes, which will let us do things like compute splits vs. a certain type of offense or defense, analyze whether 4-3 or 3-4 defenses were better in a given season, etc.
Today, we added a new feature to our popular Approximate Value metric on the site -- AV totals for kickers and punters. (Don't worry, we've warned Doug Drinen, and he hasn't suffered any adverse health side-effects that we know of.)
The methodology is described in tortuous detail on the AV formula page, but we basically looked at salary data to calibrate kicker and punter AV against our existing AV data, and used some simple metrics (kicking points added above average using distance data; punting gross yards per attempt w/ an adjustment for blocks) to measure kicking/punting performance. The best career AVs in each category are as follows:
We're still working out some AV kinks (particularly in terms of All-Pro bonuses) with certain players who played both kicker/punter and another position -- think Lou Groza -- but for the most part we're happy with the results, and we thought it was time special-teamers got their AV due.
Today, we added a small new dataset to the site's Awards Section: All-Decade Teams. We have the official All-Decade Teams from the Pro Football Hall of Fame (and, in the case of the AFL, the AFL Hall of Fame) going back to the 1920s:
In addition, we have added drive breakdowns to all of the boxscore pages since 2000 which include summaries of offensive performance for each drive (look for the "Drives" section midway through the page above the full play-by-play). Now Patriots fans can relive both the thrill of victory and the agony of defeat.
The Play Index is the name we use to refer to PFR's collection of top-notch research tools. Read below for more information on some of the applications we have made available to you, and also check out our blog posts about the Play Index. As always, if you have any suggestions or corrections please fill out our feedback form.
Every Monday, for the rest of the year, we'll be randomly selecting one twitter user who follows any three of our five Sports Reference Twitter accounts to receive a free Baseball-Reference.com Play Index account. If you are already a subscriber, we'll extend you for a year.
Sports Reference uses twitter to tweet out nuggets of information we find, notify users of new features, make occasional commercial messages, and generally enjoy ourselves. Here are the five Sports Reference twitter feeds:
It's the offseason, which means lots of news on the player-movement front. That's why we have newsfeeds on the PFR player pages, showing the latest player news from KFFL, injury reports and links to relevant PFR blog posts. If you have a blog or website with an RSS feed you can add your site to relevant player pages as well. Our Player Linker Tool will take your blog posts as you've written them and run them through a program and add links to PFR player pages where appropriate. So while you don't have the resource to create your own player pages for your site, you can treat us as your site's statistics partner, linking Eli Manning's name to our stats or any player all the way back to Y.A. Tittle and Otto Graham.
