Why Josh Smith just became unemployed

I mean, I know it's more complicated than this, but...

Thanks for the memories, Detroit Josh Smith. Your move, Kemba Walker.

PS - Yep, LeBron James and Kevin Durant are really that intergalactic. James Harden and Stephen Curry are pretty friggin' special, too.

The five most improved NBA offenses - and five that have plummeted

Here's a chart of how every team's offensive efficiency has changed from 2012-13 to 2013-14, as measured by points scored per 100 possessions. (Through the games of Jan 16. Thanks to NBA.com/stats for the data.) The five teams in green have shown the most improvement, while the five in orange have decreased efficiency the most. The NBA average is in purple.

Looking at the 5 most improved:

1. Blazers: Thanks to Wesley Matthews, Damian Lillard and Nicolas Batum, Portland is second in the NBA in both 3-point attempts and percentage. No one else is hitting more than 10 threes a game. And no other team is hitting 82% of their free throws either.
2. Suns: Phoenix had the 2nd-worst offense in the league last year. Now they're in the top ten. How? Losing Michael Beasley helped (a lot). So did spacing the floor with at least 3 shooters all the time. Gerald Green, Eric Bledsoe, Goran Dragic, Channing Frye and Marcus Morris are each taking at least three 3PA per game - and each is hitting at least 35%. Kudos to Jeff Hornacek.
3. Timberwolves: A healthy Kevin Love. Kevin Martin doing K-Mart things. Nikola Pekovic bruising people inside (53% FG). It's a dynamic offense that also doesn't give away possessions (3rd-lowest turnover rate in the NBA).
4. Wizards: The worst offense in the league last season (and especially brutal without John Wall), Washington is now just slightly below-average. When healthy, they're big, athletic, and can space the floor juuuust enough to succeed.
5. Mavericks: Dirk Nowitzki is back to being his hyper-efficient self. Monta Ellis played out of his mind for the first two months. And Jose Calderon is hitting 47% of his threes. Yowza.

And the 5 teams that have plummeted the most on offense:

1. Knicks: Last year, New York led the league by a mile in 3PA, and had the 5th-best 3p%. This year they're 8th in attempts and 17th in percentage from downtown. So they must be trying to make it up inside, right? Nope: dead last in free throw attempts and 22nd in 2P%. This offense has to be elite to compensate for the Knicks' myriad issues on defense. Right now, it's not even leaue-average.
2. Bucks: Wait, is Milwaukee actually missing Brandon Jennings? I don't know if I'd go that far... except that their three highest-usage players (Brandon Knight, O.J. Mayo and Gary Neal) are shooting a combined 41% on all two-pointers. The guards don't get the ball to John Henson and Giannis Antetokounmpo enough, and the entire team avoids the free-throw line like the plague. Yet somehow, even with that overall passivity, the Bucks have the 5th-highest turnover rate in the league. Also, Gary Neal is one of your three highest-usage players??
3. Lakers: First, without Dwight Howard and Kobe Bryant, the Lakers have cratered in offensive rebounding (13th last year, 26th this year) and getting to the line (2nd last year, 14th this time). These are both symptoms of the bigger issue: every possession is a struggle to get a quality shot.
4. Thunder: Turns out it's hard to sustain the most efficient offense in the NBA without Russell Westbrook. And with Kendrick Perkins. And Thabo Sefolosha forgetting how to shoot.
5. Jazz: Given that 5 of the top 6 Jazz players in minutes played are 23 or younger, ranking 23rd in offensive efficiency isn't bad. (The league-worst defense, on the other hand...)

The masters of getting to the free-throw line

Here's a chart of the 25 players who are getting to the free throw line the most this season (as measured by FTA / 36 minutes), and how they're doing once they get there.

Some takeaways:

• Perhaps nothing illustrates the growth on offense of DeMarcus Cousins better than this: in each of his first three seasons in the NBA, Cousins averaged between 6 and 7 FTA / 36 minutes. This year, he's the only qualified player in the NBA averaging over 10 FTA / 36. He's hitting 71% right now, right in line with his career average. If he can pull that up to 75% or higher... good golly, how do you stop him?
• LOL Dwight Howard. Let's start with the good news: he still gets to the charity stripe a ton, and he's hitting free throws at a higher rate than in either of his past two seasons. So that's nice. On the other hand, he's missed 154 FTA so far. No one else on this chart has missed more than 86 (Blake Griffin). Dwight has missed 25 more FTA than Kevin Durant, James Harden, and Kevin Love combined, and that trio has taken 550 more total attempts than Howard.
• Speaking of Durant, he's one made 3P and four FT away from shooting 50% 2P / 40% 3P / 90% FT. Amazingly, each of those percentages is actually down from last season.
• LeBron James started the season red-hot (by his standards) from the stripe, shooting almost 80% through the end of November. Since then, however, he's been just a shade over 70%. His career average is 75%.
• Tony Wroten? Tony Wroten! Philly has to be delighted that he (and his backcourt mate Michael Carter-Williams) are able to get to the line at will, especially when both are still under 21 and barely understand NBA offense. Unfortunately both of them are among the five worst on this chart at hitting their freebies. By the way, Wroten hit 72% last season in Memphis, but his 58% mark this year is exactly in line with what he shot in his lone college season, so I'm going to consider last year the outlier until further notice.
• Check out the teams that have a pair of players on this list, and how they rank in offensive efficiency. The Rockets (with Harden and Dwight) are 4th in the NBA in points per 100 possessions. The Wolves (Love and Kevin Martin) are 5th, the Clips (Blake and Chris Paul) are 7th, the Pelicans (Anthony Davis and Tyreke Evans) are 8th, and the Suns (Goran Dragic and Eric Bledsoe) are 10th. Even the less-heralded Hawks (Jeff Teague and the ever-professional Paul Millsap) are 13th. That's not a coincidence - if you can consistently run two-man actions in the half-court that get you free points, you're well on your way to a powerful offense.
• And finally, I can't not mention Swaggy P. Nick Young is getting to the line on a career-best 32% of his FG attempts, which is propelling him to a career mark in true shooting percentage as well. I understand the numerous criticisms of Mike D'Antoni - many of which are valid - but he's demonstrating again an amazing ability to put limited role players in a position to succeed on offense.

The best rebounders in the NBA, featuring Andre Drummond

Who are the best rebounders in the NBA? Looking at rebounds per game gets us a partial answer, but it doesn't account for a couple of important factors. First, different players get different numbers of opportunities for rebounds. Second, not all rebounds are created equal. Some are uncontested, while others are most definitely not.

The two charts below should give us some more insight. The top chart maps rebounding chances per game against the percentage of those chances that actually get rebounded. (We're including every player who gets at least 14 chances per game.) The second chart looks at the leaders in rebounds per 36 minutes, and breaks those rebounds into uncontested (in purple) and contested (in orange). NBA.com defines "contested" as those rebounds where an opponent is within 3.5 feet of the rebound.

Some takeaways:

• It's probably premature to say definitively that Andre Drummond is the best rebounder in the NBA. But... not by much. He's leading all 29 players in the top chart by pulling in a whopping 73% of rebounding chances. If he's near the ball, he's getting it. Even more impressively, he's doing it the hard way - he's second in total rebounds / 36 mins, and has more contested rebounds AND fewer uncontested rebounds than any of the other top 9 players in that category. What a beast. Oh, did I mention he turned 20 this summer?
• When it comes to board work, Kevin Love dishes out quality and quantity. He's averaging over 21 rebounding chances per game - nobody else in the game earns over 18 chances. That's proof of both his ability to stay on the floor and his incredible nose for the ball.
• If Drummond is the best young rebounder in the game, DeMarcus Cousins certainly isn't far behind.
• Only 29% of Dwight Howard's rebounds this season are contested, compared to 44% for Drummond and 41% for DeAndre Jordan. I have no idea what to make of this, honestly.
• Speaking of Jordan, his improvement on the boards from past seasons has been remarkable. It's partly because he's staying on the floor, playing over 35 mpg after never even breaking 29 mpg in previous season. But he's also grabbing far more rebounds on a per-36-minutes basis (13.0 this year, compared to a career average of 10.8). Combined with Blake Griffin's usual rebounding excellence, the Clips at least have a solid 1-2 punch inside. (Too bad they also have the not-so-solid 3-4-5 punch of Ryan Hollins, Antawn Jamison and Byron Mullens.)
• Shout out to Carmelo Anthony, grabbing almost 70% of his rebounding chances. He's easily setting new career highs in both offensive and defensive rebounding rates, which is doubly impressive given his sky-high usage rate.
• Anderson Varejao. Struggling.

How efficient are the NBA's highest-usage players?

Here are the true shooting %'s for the 25 players with the highest usage rates in the NBA right now (min 240 mins played).

Some takeaways:

• LeBron James is killing the NBA softly with his efficiency. By the way, the modern-era record for TS%  (min 500 FGA) is 70.2%, by Artis Gilmore in 1981-82. The record for non-centers is Cedric Maxwell at just under 68%. LeBron has a great shot at busting that mark - while taking almost 50% more shots than Cornbread did.
• Does Kevin Durant curse the existence of LeBron every day, or is it a weekly ritual? Durant's efficiency is startling and borderline historic... except it's overshadowed by this other guy at every turn. Let's just relish them both.
• Monta Ellis finally does have it all! After posting TS% of 51% and 49% the past two years, Monta is over 59% this year. That's better than Stephen Curry, Tony Parker and Kevin Love. How is this happening? Simply put, he's doing everything better: taking fewer three's, shooting them more efficiently, and getting to the line at a far greater clip than ever before (7 FTA / 36 mins, compared to 4.5 FTA / 36 the past two seasons.) By the way, if this amazing transformation keeps up, this may become one of the strongest points in the Hall of Fame resume of Dirk Nowitzki. (Speaking of Dirk, he just misses the top 25 in usage on this chart, but his TS% is over 60%. That's a hell of a two-headed foundation for an offense.)
• I'm going to excuse Russell Westbrook's inefficiency for now because he's coming back from a serious meniscus injury.He's been over 53% TS each of the past three seasons, and I expect he'll be back there soon.
• What's up with DeMarcus Cousins? After a 28% usage rate last year, he's approaching 35% this year. His shooting isn't horrible, and he's actually passing pretty well (a 16% assist rate), so it'll be interesting to see if he can sustain this new level of volume and efficiency. Has losing Tyreke Evans has been addition by subtraction for DMC?

The greatest rebounders in modern NBA history

Let's look at the best rebounding seasons in modern NBA history (1974-2013) in two different ways.

First, who's dominated rebounding on both ends of the court? In Sheet 1, I've plotted the 48 player seasons that had the highest mix of rebounding on both ends of the court, as measured by DRB% and ORB%. (Those are the percentages of all available rebounds that the player collected while they were on the court.) The size of the circles represents the number of minutes played (min 1500 mins to qualify). Thanks to Basketball Reference for the stats.

Next, I wanted to look just at defensive rebounding dominance over time. Why isolate on just def rebounds? Two reasons:

1. Offensive rebounding opportunities are often determined by the team's scheme. For example, the Doc Rivers-era Celtics teams punted on offensive rebound opportunities almost completely to focus on getting back on D. Kevin Garnett didn't forget how to grab offensive rebounds when he went to Boston. He was simply instructed not to.
2. Players with high usage rates on offense are generally less likely to have offensive rebound chances than someone who's allergic to the ball and just camps out at the basket.

So Sheet 2 shows every player since 1974 who's had multiple seasons of DRB greater than 28%. I'm looking for guys who've dominated the glass year after year.

Takeaways

- When it comes to combined rebounding on both ends, as with most things, Dennis Rodman is on another planet. His 1994-95 season is statistically the best mix of offensive and defensive board work in modern NBA history, and it's not close. But bear in mind he played only 49 games that season, thanks to a mix of butting heads with the Spurs organization and injuries. Personally, I'd put his 1992-93 at the top of his rebounding list. He played over 3300 minutes that season, grabbed over one-third of all defensive rebound chances and 18% of potential offensive boards. It's an amazing combination of stamina, talent and effort.
- Moses Malone, y'all. Young Moses was relatively thin, quite good on the defensive glass... and a preposterous beast on the offensive boards. He started in the ABA at age 19, and led his respective league in total offensive boards eight of his first nine pro seasons. Moses finished his career with just over 7300 off rebs. No one else in modern NBA history has over 4800. (Bear in mind, they didn't keep off reb stats during the Russell-Wilt era.)
- I knew Maurice Reggie Evans had a great rebounding season in 2012-13. I didn't realize his defensive board work was the best in the past 40 years. Hoovering almost 38% of available boards... wow.
- Get / stay healthy, Kevin Love and Dwight Howard. You're both on historic paths if you stay upright.
