Due to popular demand, we decided to add a dedicated page with the 2013 preseason schedule for every team:

2013 preseason schedule and results

It will also be populated with scores/results as the games are played.

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.

So let those corrections/additions pour in!

For your offseason Friday enjoyment (only a couple more weeks till training camps!) I put together some team travel maps highlighting the distances each team has to go to away games each year (back to 1970). Compare the Browns' 6,578 miles traveled (round-trip) with the 28,268 miles Seattle travels in 2013.

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:

• Pro Football Hall of Fame All-1920s
• Pro Football Hall of Fame All-1930s
• Pro Football Hall of Fame All-1940s
• Pro Football Hall of Fame All-1950s
• AFL Hall of Fame All-1960s
• Pro Football Hall of Fame All-1960s
• Pro Football Hall of Fame All-1970s
• Pro Football Hall of Fame All-1980s
• Pro Football Hall of Fame All-1990s
• Pro Football Hall of Fame All-2000s

We also assembled our own Pro-Football-Reference All-Decade teams using Approximate Value, and list those as well:

• Pro Football Reference All-1960s
• Pro Football Reference All-1970s
• Pro Football Reference All-1980s
• Pro Football Reference All-1990s
• Pro Football Reference All-2000s

Today we're rolling out our newest PFR Play Index tool: the Drive Finder. Similar to the Play Finder tool, this will let you find drives for all types of game situations, featuring all drives from 2000-2012. We include a breakdown of average time, yards, plays, points, and even starting position so you can get an idea of the situation behind each drive. Did you know the 2012 Browns average drive started at their own 30.6 yard line with them trailing by 2.8 points? Well now you do! You can also find:

• all of the Patriots' game-winning playoff drives
• all drives since 2000 which took 20 or more plays
• all 90+ yard comeback drives in 2012

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.
