Earlier this season, there was some buzz that LeBron James had lost to Kemba Walker for the first time in their 29 head-to-head appearances. However, did you ever consider who LeBron loses most often to? If you set a minimum of 10 head-to-heads (regular season and playoffs), that would be Patrick McCaw, who is 4-1 against James in the regular season and 8-1 against him in the playoffs.

This is now more easily searchable thanks to Basketball-Reference's new Teammates And Opponents tool, located in the Frivolities section of the site. This will produce a list of either every player your choice, in this case, LeBron, has played against, or played with. As an example of the teammates function, here's a link to every player Russell Westbrook has played with. You may be surprised that among players who've been in 50 games with Westbrook, Hasheem Thabeet has the highest winning percentage with him.

So try out our new Teammates and Opponents tool and see what interesting results you can find! If you have any questions or suggestions, feel free to contact us through our feedback form.

On our sites that cover the pro sports, we at Sports Reference make an effort to include portraits of the players being covered, as there is power to attaching a name and stats to a face. With that in mind, we're happy to announce both the addition of headshots for players currently participating in the 2019-20 college basketball season, as well as pictures for 500 major historical players.

If you're subscribed to our College Basketball Stathead daily recap newsletter, you may have noticed we recently added the headshots of the top 5 players for each night to give your inbox a splash of color. (And if you're not subscribed but are interested, sign up here!) Luka Garza, Markus Howard, Xavier Tillman, they've all got their faces on the site now.

As for the historical players, check out Bill Walton when he was playing college ball instead of commentating on it, or Tony Bennett's big smile back when he was shooting threes for Green Bay instead of coaching the Cavaliers. Charles Barkley when he had hair, or David Thompson rocking the 'fro at NC State are also choice additions.

We do plan to incorporate historical coach headshots in the near future as well. If you have any questions or suggestions, feel free to contact us through our feedback form. Thanks for following us!

For April 2017, MLB awarded Reliever of the Month honors to Greg Holland (NL) and Tommy Kahnle (AL) and has kept up this award through the 2019 season. With 3 years of the award in the books, we have added it to Baseball-Reference's repertoire of awards history. This will appear in the Leaderboards, Awards and Honors section of player pages as Monthly Awards. Here's a link to Edwin Diaz, who currently leads with 5 Reliever of the Month honors.

As part of our partnership with StatsBomb, FBref continues to incorporate more advanced statistics for players in the major international leagues. Additions have included expected goals, passing data and plus/minus, which you can read more about in this blog post. We have now added post-shot expected goals for goalkeepers, which uses expected goals on on-target shots to measure the shot-stopping ability of goalkeepers.

This information is available in competitions' advanced goalkeeping page. For example, here is a link to the advanced goalkeeping table for the 2019-20 English Premier League. You can read FBref's xG explainer as well as Statsbomb's PSxG explainer for more information on how these figures are calculated.

You can keep up with the latest additions of competitions coverage and new features here on the Sports Reference Blog, or by signing up for the This Week in Sports Reference mailing list. Feel free to send us any questions or suggestions through our feedback form or FBref's official Twitter account.

The NFL began handing out Player of the Week awards in 1984, but before then the Associated Press handed out their own Player of the Week awards. Thanks to compilation work by John Turney, we now have that award's history from 1963 to 1973. Notably, before 1970 there was an AFL and NFL version of the award. Len Dawson and John Hadl lead the way with 8 AP Player of the Week honors. The AP was also liberal enough with its criteria to award entire units, such as the Raiders Linebackers in Week 2 of 1973, or the entire Fearsome Foursome of Merlin Olsen, Deacon Jones, Lamar Lundy and Roger Brown in Week 14 of 1967.

With the season concluded, we're pleased to report that we've added 2019 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 and All-Pro rosters are finalized. However, there's already some interesting preliminary information to take a look at.

As of now, Lamar Jackson is the clear AV leader at 26, tied for the all-time record with LaDainian Tomlinson's 2006 MVP season. Michael Thomas, Patrick Mahomes, Dont'a Hightower and Dak Prescott round out the top 5.

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. Feel free to send us feedback via our site's form.
