On Pro-Football-Reference, while the majority of our statistics are for players, we also have a good amount of coaching data, including team ranks during a coach's tenure as well as coaching history. One of our offseason projects at PFR was to fill out the coaching history of every head coach and coordinator since 1990, and we have pushed that data out for the public eye today.

Some examples:

Tom Cable is currently an assistant head coach and offensive line coach for the Seattle Seahawks, and he's been on the West Coast for the grand majority of his career, ever since he started off as a graduate assistant for Idaho and San Diego State in the late 1980s.

David Shula had an ignominious head coaching tenure for the Bengals of the 1990s, but now we've added in his 1991 year as a WR coach that got him promoted to head coach the ensuing season.

Lane Kiffin has been out of the NFL for a while, but we've added in his latter-day college experience as an offensive coordinator for Alabama and a head coach for Florida Atlantic. Never forget he got his head coaching gig with the Raiders from a college offensive coordinator position, so anything is possible.

To get at least one actually successful coach in here, Dick Vermeil now has his 1970s stints with UCLA as well as his 1969 season as the Los Angeles Rams' special teams coordinator included in his history.

If you have any questions or suggestions, feel free to contact us through our feedback form.

Thanks to the efforts of David Vincent (R.I.P.), Baseball Reference has added originally scheduled dates of games that were made up later in the season or unplayed due to other circumstances. We have now incorporated that information into our team schedules from 1877 up to 2016, with the 2017 and 2018 seasons coming later on.

This information, which is part of the Retrosheet database, also includes the reason for the postponement or cancellation of the game. So now it's easier to know the 2007 Indians played their first "home" series in Milwaukee due to snow in Cleveland. In addition to weather-related postponements, we also mark games that were pushed due to more tragic events, such as the 1968 Pirates and several other teams that season delaying their openers due to the funeral for Martin Luther King Jr.

As a final note, a reminder that the reason there was a second game that had to be forefited on Disco Demolition Night was because of a rainout for a game previously scheduled on May 2, 1979.

With the retirement of Jason Giambi I've seen some talk from people that there are now no longer any MLB players older than them. Since I'm never one to pass up on the opportunity to make a relatively useless tool, I've added a quick Pro Football Reference page to find active NFL players as old or older than you are. Basically, we just need to hope that Adam Vinatieri keeps kicking.

Chase asked where FSU's +42.3 pre-bowl PPG differential ranked among all BCS-bowl teams historically, so I thought I'd run a quick database search:

In light of the Eastern Conference's "embarrassing" showing in games against the West so far this year, here's a rundown of how each conference has fared against the other for every year since 1951 (before 1971, the NBA had Eastern and Western "divisions" which were de facto conferences):

In the early stages of 2013-14, we are indeed seeing an historic level of inter-conference imbalance. The West's 70.8% winning percentage vs. the East is tied for the highest by one conference/division vs the other, matching the mark set by the Eastern Division in 1960.

Powered by the transcendent 59-16 Celtics (who won 10 more games than any other team), the 49-26 Philadelphia Warriors, and the 45-30 Syracuse Nationals, the East dominated a Western Division that boasted only one team -- the 46-29 St. Louis Hawks -- with a record anywhere near .500. (Aside from St. Louis, the other West teams had a combined 74-151 record that season.)

A user wrote in asking how many games each team has played vs. every division since the 2002 expansion set up the NFL's current 8-division alignment. Since we don't currently have that function in the Team Game Finder (though we might someday), I figured I'd just run a quick database search on the subject...

First, records vs. the AFC divisions:

+---------+-----------+--------------+--------------+--------------+--------------+
| team_id | division  |   AFC East   |  AFC North   |  AFC South   |   AFC West   |
+---------+-----------+--------------+--------------+--------------+--------------+
| atl     | NFC South | 11 (6-5-0)   | 12 (7-4-1)   | 12 (5-7-0)   | 12 (10-2-0)  |

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).

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).

Recently, a BBR user posed a question we get on occasion:

"[I] noticed that the team rebound totals for every team appear to be incorrect from 1956-57 to 1967-68. They are correct in 1968-69. For example in 1956-57 it shows the Celtics led the league in rebounds with 4963. When you add up the rebounds for every player on their roster the total comes to 4578. The points and assists totals match exactly. [...] It is only the rebound total that is off, and it is off for every team by a significant margin."

He's right -- you can see this by adding up the team rebound totals for each league-season and comparing it to the sum of individual player rebounds... It changes around 1968:

So what's the deal? Is this a bug in our database?

Actually, no. It's just a matter of accounting by the official scorer, because technically speaking, for every missed shot there has to be a rebound.

Starting in 1968-69 (1967-68 in the ABA), so-called "team" rebounds (rebounds where there was no clear individual who should receive credit) were no longer counted toward a team's overall rebounding total. Before that, "team rebounds" were credited at the team level, but they (obviously) didn't make it into individual rebounding totals. This is what caused the massive discrepancies between teams' rebounds and the sum of their individual players' rebounds.

Nowadays, those "team rebounds" are thrown into their own bucket, neither allocated to individuals nor to teams for the purpose of overall stat totals.

Mystery solved!
