Worst. Monday Night Football Matchup. Ever. (By combined winning percentage)

Posted by Neil on October 21, 2013

Just a quick hit of a post to let you know that tonight's MNF matchup between the 0-6 Giants and the 1-4 Vikings is, in fact, the worst ever this late in the season by combined winning percentage:

It is not, however, the worst by combined PPG margin. That honor belongs to this 1972 game between the 2-5 Patriots and the 1-6 Colts (Baltimore ended up winning 24-17).

Stat Questions: Team Passing Yards vs Individual Passing Yards

Posted by Neil on October 16, 2013

This is a question we get ALL the time... In fact, it's come up twice in my inbox over the last 2 days:

"How is a total of -11 (-1 Dallas and -10 Green Bay) passing yards figured in the Oct 24, 1965 game when Individual stats show Craig Morton for 61 yards and Bart Starr for 42 yards?"

"This query should return this game [...] Elvis Grbac threw for 504 yards, and the Raiders scored 49 points. That game was not returned by the query[.]"

In both cases, it's a question of individual passing totals seemingly not matching up to team totals. And that's because the NFL doesn't define "passing yards" in the same way for teams as it does for individuals.

Confusingly, sack yards do not count against the "passing yards" you see listed next to individual players, but they do count against "passing yards" at the team level. To put it another way, individual passing yards are always presented as GROSS yards (with sack yards not subtracted out), while team passing yards are always presented as NET yards (meaning sack yards are subtracted out).

So despite Morton & Starr's combined GROSS pass yards, there were also 114 combined sack yards in that game, leading to a record -11 total combined NET passing yards in the game. And despite Grbac's 504 GROSS pass yards, he was sacked 4 times for 30 yards, meaning KC only had 474 NET passing yards in the game.

This probably doesn't make a great deal of sense in 2013, but it does come in handy for years before QB sack data was tracked (a.k.a. the history of football up until 1969). Because of this practice, we know how many gross yards a quarterback -- and, therefore, a team -- had, as well as how many net yards they had, since sack totals were recorded for teams (but not players) before 1969. It would make for even more confusion if, starting in 1969, we all of a sudden began defining yardage for individuals differently than it had been defined in the past (though as we saw yesterday, this didn't stop the NBA from abruptly changing how team rebound totals were defined).

So it's a minor inconvenience now, but probably a necessary one from an historical perspective. And hopefully this post will reduce some of the confusion going forward (though I doubt it).

Team and Yearly Splits

Posted by Mike on October 3, 2013

Using the play-by-play data that powers our play finder, I've built detailed season split pages for each team on offense and defense, as well as league total splits and league average splits for the year. Now you can compare your team's performance by field position to the league's, or see which team is best in the fourth quarter. If you can think of a situation you want to see that's not covered here, leave a comment & we'll see what we can do.

We often get emails about some of the more... let's say "esoteric" positional abbreviations in the P-F-R database (the most confusing of which date back to the earliest days of professional football). Here's a handy guide in case you ever get stuck wondering what in the world some of these positions are:

Team Owners & Executives

Posted by Mike on September 20, 2013

Thanks to the research of Neil Paine, we now have lists of team executives and owners dating back to 1936, a page for each executive, and owner/executive lists for each team. These lists are complete for active franchises, though we have partial data for defunct franchises as well.

Drive Finder Play Index Tool

Posted by Neil on September 16, 2013

In case you missed it, here is one of our newest PFR Play Index tools: 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:

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.

Team Travel Maps

Posted by Neil on September 15, 2013

Wondering how far your favorite team has to travel this season? This summer we created 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.
