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.

On Baseball-Reference and Basketball-Reference, we've offered an option to see game logs on a team basis. If you wanted to take a look at the averages of the Miami Heat's 27-game winning streak in 2013, or how the Cardinals did in 2016 when they hit multiple home runs in 9 consecutive games, summable game logs allow you to check the averages during your specified span (done by clicking on two rows to highlight the group of games you're interested in).

Now, we've gone ahead and made that an option for Hockey-Reference and Pro-Football-Reference as well. Want to add up the goal differential during the Columbus Blue Jackets' 16-game winning streak in December 2016? Or maybe take a look at how many yards the Browns gave up in just the second half of 2017? That can now be done with the addition of summable game logs to team pages. Similarly to team game logs on Baseball-Reference and Basketball-Reference, just click on two rows and the site will sum and average the rows highlighted in that range.

Speaking from experience, Pro-Football-Reference has been a godsend to fans of the National Football League who want to investigate and sift through its near-century of history. For that reason, small additions to fill out the league's history are always appreciated, and today we've added in third-team All-Pro selections by The Green Bay Press-Gazette and Collyers Eye Magazine, where available, from 1923 to 1935. In an era where we don't have many of the statistics we can use to evaluate modern players, honors like All-Pro selections become all the more useful to help us understand how good a player was viewed by contemporaries.

Some interesting notes that come from this addition:

1. We get to fill out some additional honors for Pro Football Hall of Famers such as Johnny "Blood" McNally, Joe Guyon and Cal Hubbard. 
2. Cub Buck (aren't names from 100 years ago fun?) gets three consecutive third-team selections added to his ledger. That includes his 1924 season where he not only scored eight extra points and three field goals, but also threw a touchdown to Curly Lambeau. His reign as heaviest player to throw a TD was unrivaled until the likes of Daunte Culpepper and JaMarcus Russell emerged in the 2000s. 
3. Milt Romney was a third-team selection at wingback for his rookie season in 1923. If that name sounds familiar to you, he is indeed a first cousin once removed of former Massachusetts governor Mitt Romney.

So if you're a fan of the NFL's history, then dig into our All-Pro and other Awards and Honors pages and see what other new names and personalities from an era long gone you can discover.

I'm pleased to welcome Alex Bonilla to Sports Reference as a User Affairs Coordinator. He'll be answering user questions, working on our new Stathead.com newsletter and much more. He's on twitter at @AlexChacon_OVA. This hire brings us to ten full-time employees.

To enhance our coverage of NFL Players of the Week, we have also added an NFL Player of the Week leaderboard. As you can see, Tom Brady is the all-time leader in this honor, which dates back to 1984.

I'm pleased to welcome Jaclyn Mahoney and Jay Hutchinson to Sports Reference in the roles of Data Developer. They'll be working behind the scenes to make sure our data is accurate and updated in a timely manner. Their main focus, for now, will be helping us push FBref.com out the door this spring.

I've written a bit about them on our About Page.

With last week's announcement of the 2017 All-Pro teams, we're pleased to report that we've added 2017 Approximate Value (AV) numbers to the site for all NFL players. Note that these numbers are just provisional right now; the final numbers will be released after the Pro Bowl rosters are finalized. However, there's already some interesting preliminary information to dig through.

As of right now, Tom Brady and Todd Gurley are co-AV leaders at 19. For Brady, this represents the best season in NFL history by a player in his 40s. Gurley, meanwhile, is the youngest RB to hit that mark since Steven Jackson in 2006.

Not sure what AV is? To learn more about PFR's attempt to put a single number on each player-season since 1960 (for the purposes of comparing players across position and era), check out this link. For this year's full AV leaderboard, go here.

We have added a new section to the Awards page at Pro Football Reference. We're happy to announce we have added the NFL Network's yearly list of the Top 100 NFL Players, as voted by their fellow players every offseason. These rankings go back to 2011, and feature the statistics each of the players went on to post that season. These rankings can also be found in the Awards section of player pages. We hope you enjoy this addition and please let us know if you have any questions.

Heavy Play Index users, especially those who try to share their findings, may have noticed that the URLs for Play Index queries tend to be very long and unwieldy. Here, for example, is the URL for a simple query of most HRs in a season:

As many an infomercial host has suggested, there simply has to be a better way. Fortunately, there is! Every Play Index tool has a button in the top right that says "Make Tiny URL" Read the rest of this entry
